Internet Explorer ol numbers appear at bottom of li instead of top as expected

I'm working on a page has an ol with nested p's, div's, and li's. Internet Explorer 6 and 7 both render the numbers for the ol tag after the p element at the end (at the very, very bottom of the li tag) rather than at the top of the outermost li as expected. I'm working on a PowerPC Mac and can't do any testing. Is there some simple CSS hack to make this render the same as it does in Firefox?

You can view the live page here. I know, I'm working on positioning the sidebar. Ignore that for now.

#bordered_wrapper h2 {

ol {

ul {

    clear: right;

li p {
    clear: both;
    margin-bottom: 20px;

    float: right;
    text-align: center;
    margin-bottom: 10px;

.preview_image a {
    text-decoration: none;
}

.preview_image img {
    border-style: none;

.end {
    clear: right;

Congratulations, you are the victim of IE's hasLayout property.

Short version: You've got it easy this time. Changes these rules:

...

ol {
    font-size: 1.1em;
}

...

li.main_item {
    width: 700px;
    clear: right;
}

...

To this:

...

ol {
    font-size: 1.1em;
    width: 700px;
}

...

li.main_item {
    clear: right;
}

...

And it's all good.

Longer version: When you apply certain CSS rules to certain elements, IE 5.5+ gives those elements a property called "hasLayout" that changes how that element is rendered. Since hasLayout was a read-only property with no apparent purpose, it took quite a while before web designers caught on to the issue. Older sites (even Quirksmode.org!) still has pages that suggest twiddling padding, margins, or even using Javascript to fix these issues. If you can at all help it, don't do these things. Instead, see if you can find out what element is incorrectly being given hasLayout, and change the offending CSS so that the element no longer gets hasLayout. If that totally borks your page, use conditional comments to fix it just for IE. Here are some CSS rules that add "hasLayout" to an element that doesn't already have it:

  • position: absolute
  • float: left|right
  • display: inline-block
  • height: any value other than 'auto'
  • zoom: any value other than 'normal' (MS proprietary)
  • writing-mode: tb-rl (MS proprietary)

As of IE7, overflow became a trigger for hasLayout.

  • overflow: hidden|scroll|auto

Longest version: read the following articles.

  1. Here's all the neat things Microsoft would like you do by triggering "hasLayout".
  2. Here's the clean-language version of what web designers thought about hasLayout when they found out what was going on. Some of the same content, but includes CSS hacks and stuff.
