Is it possible to use string concatenation with the content property. I'm trying to display an image before every item in my list, but I want this image to be a link. Here's what I want to do, but I don't know how to do this. If anyone can help me out, that would be great. Thanks.

#side-nav ul li:before {
	position: relative;
	float:right;
	top: 15px;
	content: "<a href='http://url'>" + url('arrow.png') + "</a>";
}

It's not possible, you can't insert anything but plain simple text using the CSS content property. Not even <a>'s.

No, you can't do it like this. CSS will not render the tags you input. Converts it to &lt;

What is the actual URL you want to link to?

It might be "better" to add a new anchor element in script rather than use CSS. After all, you are adding function rather than style.

Here's the script if you want it...

  <script>
  
   var figures = document.getElementsByTagName("li");
   for (var counter = 0; counter < figures.length; counter++) {
    var newLink = document.createElement("a");
    newLink.setAttribute("href", "bob");
    var txtNode = document.createTextNode("Hello. This is a new node.");
    newLink.appendChild(txtNode);
  
    figures[counter].insertBefore(newLink,figures[counter].firstChild)
   }
 
 
  </script>

Ignore the naming convention, I had just written on my site and I have the figure element. You might have to extend the functionality so that other lists are ignored, but I can't be bothered to write that for free... :-)

Well if I use jquery can't I just do it all in jquery? Add both the image and the link after the certain element list item? Thanks.

Css is rendered after the HTML so no
You can try js.

If you already have jQuery, you can change my code (which does the same thing) for jQuery. The selector part of it will be easier if you use jQuery.

var $newLink = $("<a />"),
$existingListItems = $("#side-nav ul li");
$newLink.attr("href","http://url")
.text("Here's my new item")
.css({
position: "relative",
float:"right",	  
  top: "15px"
});
$existingListItems.prepend($newLink)

Please don't use javascript for this.

Or if you do, at least consider what will happen if your user doesn't have js enabled. I don't see why

<ul>
<li><a href="somewhere"><img /></a><p>List element text</p></li>
...
</ul>

Wouldn't work for you, though.

I was assuming he didn't have access to the code behind that renders these elements. Then again, I don't get why he would want a link in the side nav that isn't already there. It's a nav bar... why add an image link in there? If it's for visible purposes, then I would advise adding it as a background image.

Then again, it might help if he listed his actual problem rather than for just a solution to an isolation code issue.

Fair enough. If there's already a link in a <li> and he can't get at the source, appending with js is probably the best way to go.

Thanks guys. Got it working with jquery. Heres the code I used.

$(document).ready(function() {
	$('<img src="/images/big-arrow.png" alt="Arrow" width="22" height="22" border="0" />').appendTo('#side-nav ul li');
  
	$('#side-nav ul li img').css ({
		position: 'relative',
		float: 'right',
		top: '-30px',
		left: '-5px'	  
	});

});
