Changing CSS for last <li>

I am wondering if there is some way to change a CSS attribute for the last li in a list using CSS. I have looked into using :last-child, but this seems really buggy and I can't get it to work for me. I will use JavaScript to do this if necessary, but I want to know if anyone can think up a solution in CSS.

:last-child is really the only way to do it without modifying the HTML - but assuming you can do that, the main option is just to give it a class="last-item", then do:

li.last-item { /* ... */ }

Obviously, you can automate this in the dynamic page generation language of your choice. Also, there is a lastChild JavaScript property in the W3C DOM.

Here's an example of doing what you want in Prototype:

$$("ul").each(function(x) { $(x.lastChild).addClassName("last-item"); });

Or even more simply:

$$("ul li:last-child").each(function(x) { x.addClassName("last-item"); });

In jQuery, you can write it even more compactly:

$("ul li:last-child").addClass("last-item");

Also note that this should work without using the actual last-child CSS selector - rather, a JavaScript implementation of it is used - so it should be less buggy and more reliable across browsers.

I've done this with pure CSS (probably because I come from the future - 3 years later than everyone else :P )

Supposing we have a list:

<ul id="nav">
  <li><span>Category 1</span></li>
  <li><span>Category 2</span></li>
  <li><span>Category 3</span></li>
</ul>

Then we can easily make the text of the last item red with:

ul#nav li:last-child span {
   color: Red;
}

I usually combine CSS and JavaScript approaches, so that it works without JavaScript in all browsers but IE6/7, and in IE6/7 with JavaScript on (but not off), since they does not support the :last-child pseudo-class.

$("li:last-child").addClass("last-child");

li:last-child,li.last-child{ /* ... */ }

You could use jQuery and do it as such way

$("li:last-child").addClass("someClass");

One alternative for IE7+ and other browsers may be to use :first-child instead, and invert your styles.

For example, if you're setting the margin on each li:

ul li {
  margin-bottom: 1em;
}
ul li:last-child {
  margin-bottom: 0;
}

You could replace it with this:

ul li {
  margin-top: 1em;
}
ul li:first-child {
  margin-top: 0;
}

This will work well for some other cases like borders.

According to sitepoint, :first-child buggy, but only to the extent that it will select some root elements (the doctype or html), and may not change styles if other elements are inserted.
