Using Prototype to emulate :last-child on IE6

Usually it's easy to find a CSS hack to deal with Internet Explorer's oddities... not so with the :last-child pseudo element, at least as far as I can tell. But using the Prototype javascript library, I was able to build a suitable replacement in 3 lines of code (it could have been 1 if I didn't care about readability or expandability).

Here's my scenario. I have a list of items, and I'm using CSS to turn them into a simple horizontal menu (see here to explain). To the right of each item, I want a vertical bar (like a |) but properly aligned, and not on the last item. So, I used the following css, putting a right-hand border on all but the last element:

ul.menu {
float: left;
padding: 0;
margin: 0;
list-style: none;

ul.menu li {
float: left;
position: relative;
padding: 0px 5px;
border-right: 1px solid #E00000;

ul.menu li:last-child {
border-right: 0;

<ul class="menu">
<li>First Menu Item</li>

The results: perfect in Firefox, not so in IE6: the last item in the list still has a border, because the :last-child pseudo-element isn't supported.

So, instead, I'm using the following javascript (this won't work without Prototype):

document.getElementsByClassName('menu').each(function(menu) {
$($(menu.immediateDescendants()).last()).setStyle({borderRight: '0'});

Bingo! No border-right on the last menu item, in IE or Firefox. Yay!


LinuxFest Northwest 2007!

The 8th annual LinuxFest Northwest 2007 is rapidly approaching... April 28th & 29th at BTC.

This is the first year that I'll be presenting - on OpenOffice, and digital photography. I hope I don't flop.

See the Press Release for more info.

First. Post. Ever.

Okay... I think enough people listen to me ramble on a regular basis that it's time to make it a bit more formal.

If for no other reason, at least I'll have a place to review and refine my ramblings in a more concrete format than, well, verbally rambling. ;-)
