jQuery Before After

A jQuery plugin for adding :before and :after support to browsers without generated content features.

Getting Started

Download the production version or the development version.

For parsing a single stylesheet

<link rel="stylesheet" type="text/css" href="styles.css" />
<script src="jquery.js"></script>
<script src="dist/jquery.beforeAfter.min.js"></script>
<script>
  jQuery(function($) {
    $(document)
      .beforeAfter({
        stylesheet: 'styles.css'
      });
  });
</script>

For parsing all linked stylesheets

<link rel="stylesheet" type="text/css" href="styles-1.css" />
<link rel="stylesheet" type="text/css" href="styles-2.css" />
<script src="jquery.js"></script>
<script src="dist/jquery.beforeAfter.min.js"></script>
<script>
  jQuery(function($) {
    $(document).beforeAfter();
  });
</script>

Documentation

Add the script after your stylesheet and jQuery, then create your css with before and after pseudo class as well as the respective class preceded by a direct child selector >.

#wrapper h1:before, #wrapper h1 > .before

Currently the plugin only supports single characters values being passed through the content property

For example

#wrapper h1:before {
  content: '.'
}
#wrapper h1:after {
  content: '...'
}

Would yield

<div id=#wrapper">
  <div class="before">.</div>
  <div class="after">.</div>
</div>

I'm aware of the problem and will be fixing it in future releases

Supported

• Non-ordinal pseudo selectors :before and :after
• Multiple and single stylesheets
• Single stylesheet configuration option {stylesheet:'styes.css'}
• Single character content: "." content injection

Unsupported

• Multiple ::before and ::after pseudo-elements using ordinals :before(#), :after(#)
• Chained pseudo selectors :first-child:after
• Multiple character content: "..." content injection

Examples

Stylesheet

#wrapper h1:before, #wrapper h1 > .before {
content: ">";
margin-right: 10px;
color: white; }

#wrapper h1:after, #wrapper h1 > .before {
content: "_";
color: white; }

#wrapper p:before, #wrapper p > .before {
font-family: impact;
content: "“";
font-size: 52px;
color: grey;
line-height: auto; }

#wrapper p:after, #wrapper p > .after {
content: "”";
font-family: impact;
font-size: 52px;
color: grey; }

Note the class selectors on the same line as the pseudo class

#wrapper h1:before, #wrapper h1 > .before

While the plugin will not add true pseudo classes you will get containers .before, .after that will behave exactly the same.

Contributing

In lieu of a formal styleguide, take care to maintain the existing coding style. Add unit tests for any new or changed functionality. Lint and test your code using grunt.

Important notes

Please don't edit files in the dist subdirectory as they are generated via grunt. You'll find source code in the src subdirectory!

While grunt can run the included unit tests via PhantomJS, this shouldn't be considered a substitute for the real thing. Please be sure to test the test/*.html unit test file(s) in actual browsers.

Installing grunt

This assumes you have node.js and npm installed already.

1. Test that grunt is installed globally by running grunt --version at the command-line.
2. If grunt isn't installed globally, run npm install -g grunt to install the latest version. You may need to run sudo npm install -g grunt.
3. From the root directory of this project, run npm install to install the project's dependencies.

Installing PhantomJS

In order for the qunit task to work properly, PhantomJS must be installed and in the system PATH (if you can run "phantomjs" at the command line, this task should work).

Unfortunately, PhantomJS cannot be installed automatically via npm or grunt, so you need to install it yourself. There are a number of ways to install PhantomJS.

• PhantomJS and Mac OS X
• PhantomJS Installation (PhantomJS wiki)

Note that the phantomjs executable needs to be in the system PATH for grunt to see it.
