An Exotic CSS Hack for Internet Explorer

Here is a less known and rather exotic CSS hack, visible for Internet Explorer based on a rendering bug. Unfortunately, it is visible both in versions 6 and 7, but still it can be useful as a last resort for styling.

And here it comes:

h1
{
 color: green;
.color: red;
}

Internet Explorer 6 and 7 will render <h1>...</h1> in red, while all other browsers will disregard the dot-prefixed property.
