On one of my surfs on the internet I stumbled onto a page that showed a technique for styling of html comments in Interent Explorer. I took an interest in it since this is the side effect of IE looking inside any html comments to establish if they are conditional comments.
This text should flow along the right side of the blue, orange and green elements floated left as is seen in all other non IE browsers. The same should happen also with IE since the container doesn't have hasLayout but since I just happened to use the unversial selector to style the floats within the container, part of the style clear:both is applied to a comment.
<div>A float before the container containing another two floats</div>
<div class="container">
<div>A float</div>
<div>A float</div>
<!-- comment -->
</div>
