Directions

"Outside, rightside" is what the airport guy at the gate says when asked about driving directions to downtown Frankfurt.

Learning Flexbox

Flexbox Froggy is a game that helps you gain practice with flexbox properties. It's a fun game that you should try!

justify-content is a CSS property that aligns items along the main axis. The default main axis is row but you can set it to column with flex-direction: column. So if your main axis is row, then justify-content will align items horizontally. But if you reset it to column, then the alignment will be done vertically. This is an important distinction and one that is not clear in Flexbox Froggy because on their Level 2 page they state that the property aligns items horizontally.

Possible values for this property are flex-start, flex-end, center, space-between, space-around and space-evenly.

When the main axis is the row, flex-start aligns items to the left side of the flex container, with flex-end items align to the right side of the flex container. If main axis is column, then flex-start will align flex items to the top of the flex container and flex-end will align them to the bottom of the container.

With space-between, there is no space to the left of the first item or to the right of the last item. The space between all the items is equal. So items display with equal spacing between them as Flexbox Froggy states.

space-around puts equal spacing between the items but adds space to the left and to the right of the first and last items that is equal to half the space in between items. Flexbox Froggy says that space-around is equal spacing around items.

Then, space-evenly similar to space-around except that the left and the right spacing is equal to the space that is between the items instead of being half.

align-items is a CSS property that aligns items on the cross axis. So there's the main axis that you can set to row or column and your cross axis is the perpendicular to your main axis. If you main is row, then align-items will do the alignment vertically since the cross axis is the perpendicular y-axis.

The values for this property are flex-start, flex-end, center, baseline and stretch. Assuming the default value of row for the main axis, flex-start will align items to the top of their container, flex-end will align items to the bottom of the container, and center will align items to the vertical center of their flex container. Just keep in mind that if the main axis was the column, then flex-start will align items to the left of their container, flex-end will align them to the right.

flex-direction property can be set to row which causes the flex items to be displayed horizontally as a row. If set to column, then flex items are displayed vertically as a column. row-reverse and column-reverse are the same things but in reverse order. The default value for flex-direction is row.

flex-wrap property accepts nowrap, wrap, wrap-reverse. In nowrap, every item fits into a single line, in wrap, items wrap around to additional lines, wrap-reverse does the same in reverse. The default value is nowrap.

flex-basis property sets the size of the flex item along the main axis. If the main axis is row, then it controls the width, if main is column, then it controls the height. It can be set to px, percentages, or any other available units. flex-basis is a property for the flex items.

I wrote a Javascript program to produce the CSS rules for a Flexbox grid system, given a number of columns.

flex-flow property is a shorthand for flex-direction and flex-wrap. To set the main axis to row and set the flex-wrap to wrap, you can write, flex-flow: row wrap.

This file shows the difference flexbox can make for centering both horizontally and vertically (sometimes called the "holy grail" of CSS styling). You can achieve this by setting justify-content and align-items to center. Given flex-direction of row which is the default, first property aligns items horizontally, second property vertically.

Adding a New Property to an Object

In Javascript, you can add new properties to an object using dot notation or square bracket notation.

var myObject = {
      key1: "val1",
      key2: "val2",
      key3: "val3"
};

DOT NOTATION:

myObject.key4 = "val4";

Object { key1: "val1", key2: "val2", key3: "val3", key4: "val4" }

SQUARE BRACKET NOTATION:

With square brackets, it'll want the key name as a string.

myObject["key5"] = "val5";

Object { key1: "val1", key2: "val2", key3: "val3", key4: "val4", key5: "val5" }

Evolution of CSS Layouts

CSS provides a number of properties that affect the layout of elements on the page, including those associated with floats, positioning, inline-block, columns, flexbox and grid. Some of these CSS features are not generally useful for laying out entire pages. Positioning, while it looks promising at first, is problematic when elements have a variable heights based on content from a database for example, making it impossible to know ahead of time where to place each element.

Inline-block is good at flowing blocks next to each other and wrapping to the next line when necessary, but it can’t easily create layouts that span columns/rows. CSS columns are good for one purpose: laying out text in multiple columns, while flowing text from one column to the next, but it is not for page layout. That leaves: floats, flexbox, and grid, which are are the main focus here.

Floats have been the tool of choice for page layout for many years. They have the advantages of universal browser support, and the ability to flow other page elements around them, or below them with clears. Many page layouts can be achieved with floats, but they do not provide for vertical centering, and can’t produce the “holy grail” layout where elements are centered both horizontally and vertically. They are also complex to use, and were not intended for page layout.

Flexbox is a major advance for page layout. It’s not as universally supported in browsers as floats, but support is good and getting better. Flex items in a flex container will adjust their sizes based on the width of the container and available space. The “holy grail” layout is achievable with both horizontal and vertical centering. One disadvantage of flexbox is that it is only one dimensional. It can layout a row for each flex container, and column spanning is possible by using multiple flex containers, but two dimensional layouts with both row and column spanning are harder to achieve and generally require multiple levels of nested flex containers.

Grid is designed to solve the problem of global page layout. Unlike flexbox, it works in two dimensions, allowing you to control both the row and column positioning and spanning of elements. Like flexbox it intelligently resizes boxes based on the size of the container and available space. Browser support is not yet as good as flexbox, but it will be widely supported in the next year or two.

Grid is best for laying out large areas of the page, but for UI elements, or things like image galleries, flexbox is still the tool of choice as it can handle a variable number of elements (e.g. a variable number of images for an image gallery), and is still the best way to perform vertical centering. Thus, the ultimate “best” choice for page layout is a combination of grid and flexbox, with grid controlling the big picture, and flexbox for individual UI elements. At last, floats can now return to their original intended purpose of flowing paragraph text around images!

CSS Grid

I just learned this technique from Jen Kramer. You can use CSS Grid to create a layout that looks like an existing Mondrian painting.

Start with the painting you want to re-create, and identify all the grid lines, both vertical and horizontal. To determine the vertical grid lines, start with number 1 at the far left, then scan across the painting. Anywhere you see the right edge of a box, create the next vertical grid line. Number them in sequence from left to right.

Do the same for the horizontal grid lines. Grid line 1 is at the top of the painting. Then anywhere you see the bottom edge of a box, create the next horizontal grid line.


Now that you have the grid lines defined, you can easily determine the grid-row and grid-column values for each box. For example in the drawing above, box "e" has grid-row: 3/6; and grid-column: 2/3.

Next you need to determine how wide each column is and how tall each row is. Put these dimensions into the properties "grid-template-columns" and "grid-template-rows" of the grid container. When measuring these dimensions be sure to not include the black gaps between the boxes. For example, for row 2/3 in the diagram, measure from the top of box "g" to the bottom of box "b".

You'll also need measurements for the horizontal and vertical gaps between the boxes. Put these measurements into the "grid-gap" property of the grid container.

Next set the background colors of your boxes. The container should have a black background, and various boxes within the container should have their own background colors to match the original painting.

Regular Expressions

/ [^ ] * / g Door County is beautiful year-round

Match a sequence of zero or more characters that are not a space. The /g in the first one
above makes the match global.

/ [^ ] * / Door County is beautiful year-round

Without /g only the first occurrence in the string is matched.

/ .*[ ] / U Door County is beautiful year-round

Match a sequence of zero or more characters that ends with a space. The dot (.) will match any character, including spaces. The * says zero or more. Then there is a space, so the string we are matching must end with a space character. The /U option makes it "ungreedy", so that it matches the first, smallest substring it encounters, rather than the longest substring.

/ ^https?:\ / \ / / http://www.https.com

Match "http://" or "https://" at the beginning of a sequence. s? says match a single s if there's one otherwise skip. The two forward slashes which are special characters have to be escaped with two backward slashes.

Some regex rules:

• Dot (.) matches any character, except newlines. If you provide a /s modifier then it will match newlines too. Example: /^The.*/s would match any sequence of text where the first line starts with the word "The", until it reaches the end of the text being searched.
  
• If you need to explicitly match a dot (aka period), then you need to escape it. Let's change the example above as follows: /^The.*\./s Now it will only match until it encounters a period, which could be on a different line of the text.
  
• The ^ character in the above examples means match from the beginning of the text being searched.
• You can also match at the end of the text being searched with $. So /\.$/ would match any string that ends with a period.
  
• Instead of matching zero or more, you can also match one or more using +
• You can also match zero or one, using ?
• Curly braces let you define a length range you want to match, so you write {minlength,maxlength}. Example: Suppose you want to match a series of the character "a" that has a length between 3 and 6. You can do it like this: a{3,6}
• Square brackets defines a set of characters to match. So [ab] will match either a or b. This could also be written as [a-b]. If you wanted to match any lower case alphabet character, you'd write [a-z].
• You can also use an "or", so that you match one string or another. Suppose you want to match "abc" or "xyz". You write it like this: /(abc)|(xyz)/ Actually the parenthesis are not needed, but are good for making it clear.
• Note that the starting and end slashes / are the delimiters of the regular expression (the start and end). You can place modifiers, like the g after the ending slash to change the way the regular expression is interpreted.

Secure Shell

If you SSH into the command line in your server, or SFTP into your server, or use github, you'll need a SSH key. On your Mac, type cd~/.ssh and you'll be taken to the hidden ssh directory. Hidden files receive a period in the front. A directory listing (ls) will give you the private and public keys, id_rsa and id_rsa.pub. If you already have these keys, you can write over them for the sake of this exercise. First copy both keys in backup files.

Then let's run the keygen command from the terminal: ssh-keygen -t rsa -C "myblog@gmail.com"

which will generate a new set of keys. One of the parameters "rsa" is a type of encryption scheme. ls -l will show the new and the old backup keys.

To add the new key to the ssh-agent: ssh-add id_rsa

Do a "cat id_rsa.pub" and copy the contents of your public key. Then go to your github account, and under Profile, find "Settings" and choose "SSH keys" from the left pane. Add "New Key" then test your new key by doing a pull to make sure everything still works with github. You'll also be copying the new public key over to your server.

To connect to github.com over SSH and test your new key:

$ssh -T git@github.com

If you receive a message telling you that you have successfully authenticated, then all is well.

Chrome Debugging from JSFiddle

I didn't know you could do this. I just learned about it. Bring up the Developer Tools either by pressing Command, Option and J together or choosing View > Developer > Developer Tools. Stay at "Sources", and expand fiddle.jshell.net in the left pane. Choose index which will show you your code.

httpd.exe

is short for HTTP Daemon processes. If you are having port issues with Apache, terminate all the httpd.exe processes. Apache starts up multiple processes because it is expecting to handle multiple incoming requests and hand off the requests to different child processes for faster performance. If you kill off one of the child processes, the httpd parent process will automatically restart the child once it detects that the child is dead. None of this sounds good but that's the terminology and there's even a "daemon" in there. So to kill httpd successfully you have to kill the parent first.

git

To see if Git is installed on your computer: $git

If you don't have git, to install it: http://git-scm.com/downloads

To find out which version of Git that you have: $git --version

"which" tells you where the command is located on the disk so it gives you the path to it. It will only work on executables. To find out where Git is installed: $which git

There's one file called .gitconfig in the home directory with global git settings. To setup username and email key to associate with your commits:
$git config --global user.name "Josephine March"

To make your Git color coded: $git config --global color.ui true

If you change your permissions, git will ignore it if you run this command:
$git config --global core.filemode

Telling git to use nano as your CL text editor. This is very helpful with merges.
$git config --global core.editor nano

To see all the configurations:
$git config --list

To add a single untracked file into the repository:
$git add {filename}

To add all untracked files into the repository:
$git add .
$git add --all

To show what changes have been made:
$git diff

To show what changes have been made in a single file:
$git diff {filename}

Adding a file is staging. If you want to undo a stage:
$git reset HEAD {filename}

If you make changes in a file that's in a git repository and you have not yet staged them, you can reverse the changes with this command:
$git checkout {filename}

d r w x r - x r - x Miné Jan 31 22:00

First slot: Is it a file or directory? Next set of triple slots is for the User, then the next three is for the Group and finally the last 3 spots is for Everyone. File permissions can also be represented using octal notation. r is 4(2^2), w is 2(2^1), and x is 1(2^0). So if it's readable, writeable and executable, it means it's a 7. If a file or directory is readable and executable but not writeable then that's a 5. You can convert between symbolic and octal representation using this tool.

How to Hang a Picture

Never one good with a level, two by fours, and hanging, I consider myself successful if a picture is not noticeably crooked. But if you wanted to do it perfectly, the experts have figured out the science behind hanging pictures:

© cssbakery.com

The rule of thumb is to hang your picture at anywhere between 56” and 60” on center. For 57 inches, "on center” means that the middle of the picture is always 57” from the floor.

Measuring from the floor, mark 57” on the wall. Measure the height of your picture and divide by two. This is your center. Measure the top of your picture to its tightened wire, tw.

Subtract tw from ½ the picture’s height. This number will tell you how far above your initial 57” mark you should place your hook.

Example: A 20” tall photo with a tight wire located 2” below
the top should have a hook placed at 8” above the mark. 10” – 2” = 8”; the hook should be placed 65” off the floor.

CSS Vendor Prefixes

When a new CSS property is being developed, and does not yet have a final, consistent implementation across browsers, you want to write it using vendor prefixes for each browser. That's a total of four statements with vendor prefixes followed by the official, unprefixed property for future use when the new property's implementation is completed.

To review the prefixes, we have: -webkit- for Google Chrome and Safari, -moz- for Firefox, -ms- for Internet Explorer and -o- for Opera. If you are unsure whether a CSS property needs a vendor prefix, there's a website which will answer that question for you.

The picture shows a mountain range on the Pacific Crest Trail. This is a follow up to a question in a previous image grid post. In this post, I have the first image displaying larger than the rest. The only significant difference in the code between this and that earlier post is the CSS rule that allows the first image in the list to be larger (CSS selector: #grid li:first-child img). The same thing could have been accomplished by giving the first li an id and targeting that id with the CSS rule. e.g. id="big-image" and #big-image. The other modification was to change the widths and heights in the CSS to reflect the different image sizes I am using here. Your grid images will likely be self-descriptive and distinct. The reason I used cutups from a single image was for simplicity.

Converting Microsoft Word Docs to XML and Processing with PHP's SimpleXML

In this post, I'll describe how to do automated processing on a set of Microsoft Word documents. The task is to compare an old version of a document to a new version section by section, and generate an output table listing sections that were modified, added, deleted, or stayed the same.

You can do this sort of thing manually in Word by opening up the document and telling Word to compare it with the older version of the document.  Word will show you the diff marks and you could then scroll through the document and record all the section numbers and whether there are changes or not.  Very labor intensive and tedious.  In this case there are dozens of pairs of documents to be compared, and the whole process will need to be repeated every month as new versions of each document are created.  Clearly the manual approach would not work - this has to be automated.

9-Slice Scaling

The CSS3 Backgrounds and Borders spec defines a new property called border-image. This is a powerful new way to draw borders of an element, using an image instead of a fixed color. But the usefulness of this property goes beyond just replacing border colors with parts of an image. It can be used to perform 9-slice scaling. This is a scaling technique where you divide an image into a grid of 9 images, like a tic-tac-toe grid. Then when you perform scaling, some of the 9 sub-images are scaled and others are not. Specifically, the corners are not scaled at all, whereas the non-corner images (the center and four sides) are scaled. This is shown in the diagram above.

Visual Depth: CSS Box Shadow Property

I added a thin line of shadow to two divs in my footer using the CSS box-shadow property which takes 6 parameters, h-shadow, v-shadow, blur, spread, color of shadow and inset. First two parameters are required, the rest are optional. Since I want the shadow to appear as a horizontal line, I'm going to be moving the v-shadow 2 pixels and doing nothing in the x-axis which is the h-shadow. So far, box-shadow: 0 2px. My blur is 2 pixels for the first div, color is self-explanatory, I chose inset to have the shadow fall inside the div. [box-shadow: 0 2px 2px #397896 inset;] To see the effect, scroll down to the footer below or click here.

You can use the Bluprint CSS framework to easily create complex multi-column layouts. Some people are against using CSS frameworks because the class names are not semantic, and are instead used to specify the layout.

Configuring Filezilla to Access SFTP Servers

ileZilla is an open source FTP/SFTP client that lets you drag and drop files between your local machine and your server. I'm going to write the instructions for setting it up. (There is also a Filezilla FTP/SFTP server, but I'm just talking about the client). A quick note for CSS people: I made the dropcap that started this paragraph by floating the red FileZilla bitmap to the left, and then giving it a right margin of 10 and top margin of 4 pixels.

If you are not familiar with FTP/SFTP, these are just protocols for transferring files. The protocols are described in RFC 959 and this Internet draft. A protocol is just a set of rules for how to exchange messages and data between computers.

On a typical Linux server there will be a SSH deamon process that handles incoming SSH and SFTP requests. A deamon process is a Unix/Linux program that's always running. So, Filezilla running on your local machine talks to the deamon process/program running on your server to accomplish the file transfer.

Fonts for the Web: Typekit by Adobe

Typekit Adobe provides online fonts for websites.  You can sign up for different plans here.  Here are the steps for using the service:

1. Go to www.typekit.com and Sign In (upper right).
2. In the pulldown at the upper right, select the site to work with.
3. Click "Launch Kit Editor"
4. Find a font and click "Add to Kit"
5. Now in the typekitEditor, add a selector for the new font and click Add.
6. There may be multiple weights and styles available, if so choose the ones you want. Note that the more you add, the more your kit download will grow in size.
7. In your markup, use the selectors that you added for the font.

Also: If you haven't already embedded the kit code in the section of your page that will be using the fonts, then in the typekitEditor, click "Embed Code" (at upper right). Cut and paste the two script sections into your document head.

To delete a project that you no longer need, go to "Launch Kit Editor". "Kit Settings" link in the upper right corner of the Kit Editor takes you to a page where you are given the option to delete the entire project.

I am using a Typekit font for my blog post headings. Adobe added a grey colored, fixed positioned Typekit colophon badge in the bottom right corner of my blog when I initially set it up. Since I pay for their services, I don't feel the obligation to advertise for them in the blog. To remove their logo, go to "Launch Kit Editor">"Kit Settings">"Colophon Settings" and uncheck "Enable Colophon Badge".

Using Notepad++ to Edit Files on the Server over SFTP

For quick tasks and transfers, FileZilla, an SFTP client, is great but manually uploading local files to the server via standalone FTP/SFTP clients can waste time if there's a lot of back and forth. By configuring the built-in SFTP client within Notepad++, you can edit files directly from the server, validate from the browser - Tools option in Firefox Web Developer Add-on gives you direct access to W3C HTML and CSS Validators - and be finished in a flash.

Notepad++, written in C++, is a source code editor, not a word processor.

SETTING IT UP

• In Notepad++ go to the Plugins menu and select NppFTP->Show NppFTP Window.
• Click on the "gear" icon (6th icon from the left).
• Choose "Profile Settings"
• Click the "Add new" button.
• Enter the name of the new profile and click OK.
• Enter the hostname which is the full URL.
• For connection type choose SFTP.
• Leave port number at 22.
• Enter username and password.
• For Initial remote directory, enter: public_html
• Click "Close"

CONNECTING

Click the connection list icon is NppFTP. and choose the server you want to connect to. The first time you connect to a given server you will be asked if you trust the host key. Say yes. You shouldn't be asked again after the first time. Now you should see the directory structure on the server. Choose a file to edit and double click it. Make your edits, and Save the file. Notepad++ will send the changed file up to the server.

Changing File Associations in Windows

Microsoft Word's been after me, popping up every time I click on a text file. Thinking I’ll be on WordPad, I am taken to the trial version of Microsoft Word instead, which asks me for a key, and registration that I do not have. You are forced to click through a series of buttons before Microsoft lets you go.

Here are the instructions for changing file associations in Windows 7. For Windows 8, see my notes after the list.

From the Start menu:

• Choose “Default Programs”
• Choose “Associate a file type or protocol with a program”
• Wait while it loads...
• Double Click on the extension (e.g. .doc, .rtf).
• Double Click on program to use: e.g. Wordpad.
• If you don’t see the program you want, click the little pulldown icon on the “Other Programs” line, then choose.

The instructions for Windows 8 is the same but finding the Default Programs has changed. Click on the far edge of the task bar which brings up a group of functions that include the magnifying glass. Choose search and type in Default programs. Follow the instructions starting from step 2.

jQuery and jQuery UI

jQuery is a Javascript library that allows you to easily manipulate - compared to writing your own raw Javascript - your HTML document, handle events such as mouse clicks and perform AJAX calls to a server. It hides many cross-browser inconsistencies from you. It's also easy to extend by writing plug-ins.

jQuery UI provides reusable user interface components including things like datepicker, tabbed interface, accordion and dialog boxes. It also makes it easy to create drag and drop functionality. You can customize the appearance of the components - called widgets - using a number of predefined themes or you can roll your own.

When you download these libraries, you have the option of using a minified, smaller version or the more readable version that includes all the whitespace formatting and commentary.

• jQuery UI, currently at 1.8.18

A Simple Plan

"An attempt to rob a jewelry store failed dramatically when the shop owner shot one of the intruders. The men fled the store and jumped into a Ford minivan, where a waiting driver took them around the corner and they all switched to a Chevy Tahoe. The nervous robbers crashed their SUV into a parked car less than half a mile from the store, sending the four occupants running in different directions. All were quickly apprehended by police. The four uninjured suspects ages ranging from 18 to 22 who did not realize that the police station was only four blocks away from the jewelry store, were booked into the local jail." -Yahoo News

Testing in IE7/IE8 using IE Compatibility Mode

Microsoft has never supported installing multiple versions of IE on a single PC. (They do provide some virtual machine images for running older version of IE, but that's not the same as having multiple IE versions on the same Windows OS instance.) To run virtual machines, you have to own Windows 7 Pro or Ultimate, it will not work with Windows 7 Home Premium.

But there is still something that everyone can do: You can tell IE to go into "compatibility mode" where it behaves like an older version of IE. For example, if you are running IE8 or IE9, hit the F12 key to bring up Developer Tools. Now go to the "Browser Mode" pull down menu, and select IE 7. Your page will be re-rendered in IE7 mode.

Writing a Generic CSS Blockquote Class

People do odd things in an emergency and we all have stories of ludicrous situations in an emergency which we laugh afterwards, if we are still alive.

My favorite one is of the third mate of a merchant ship who, after a tremendous explosion and thinking his ship had been torpedoed, leapt naked from his bunk and jammed both his legs down one leg of his shorts, so immobilizing himself that he had to crawl out on deck on his hands and knees. Fortunately the explosion hadn't come from a torpedo but from a closely dropped depth charge.

I wanted to post a funny paragraph from a paperback I've been reading. Since we had covered CSS blockquotes before, I went back to find out how to use that class with my quote.
