Clicking on the link "Basic HTML data types - Colors", the IE browser does not follow it, IE loads the target page, but doesn't jump to the section Colors on the page.

exaple:

<html>
<head>
<title>Colors link</title>
</head>
<body>
<p>Source: <a href="http://www.w3.org/TR/html4/types.html#h-6.5">Basic HTML data types - Colors</a>
</p>
</body>
</html>
