:after and :before CSS pseudo elements hack for Internet Explorer 7

I am using :after and :before CSS pseudo elements and it is working fine in Internet Explorer 8, and all modern browsers but it is not working fine in Internet Explorer 7. Are there known hacks to work around this in Internet Explorer 7?

with any pure CSS hack it's not possible.

Use IE8.js http://code.google.com/p/ie7-js/

It has support for this. http://ie7-js.googlecode.com/svn/test/index.html

test page also there

after - http://ie7-js.googlecode.com/svn/test/after.html

before - http://ie7-js.googlecode.com/svn/test/before.html

Edit after 1st comment

You can just keep this js for IE6 and 7. other browser will not read it.

<!--[if lt IE 8]>
<script src="http://ie7-js.googlecode.com/svn/version/2.1(beta4)/IE8.js"></script>
<![endif]-->

And if you are already using jQuery in your project than you can use this plugin

I was using IE8.js (http://code.google.com/p/ie7-js/) in a project and I had to remove it because it blocked IE7 between 10/15 secs.

To mantain the content generated with :after and :before pseudo-elements, without IE8.js, I did the following:

   .tabs {
     *zoom: expression( 
          this.runtimeStyle.zoom="1",
          this.appendChild( document.createElement("small") ).className="after"
         );
   }

   .tabs:after,
   .tabs .after {
     content: '';
     display:block;
     height:10px;
     width:100%;
     background:red;
   }

I prefer this way rather than with javascript, because this will keep all selectors in the same place :)

To before and after you can use this:

.tabs {
    *zoom: expression(
        this.runtimeStyle.zoom="1",
        this.insertBefore(
            document.createElement("div"),
            this.childNodes[0]
        ).className="before",
        this.appendChild(
            document.createElement("div")
        ).className="after"
    );
}

...

.tabs::before, .tabs .before {
    display: block;
    width: 10px;
    height: 20px;
    background-color: #eee;
    float: left;
}
.tabs::after, .tabs .after {
    display: block;
    width: 10px;
    height: 20px;
    background-color: #c0c;
    float: left;
}
