xhtml validation issues in wordpress

[dthomas31uk]

Hi guys am trying to get my site validated and have got the following errors. Any ideas how I can rectify this

The default scripting language must be specified for an intrinsic event:
<div class="details" onmouseover="this.className='details2'"
onmouseout="this.className='details'">

I think it has something to do with the content type in my header which I have the following

<meta http-equiv="Content-Type" content="<?php bloginfo('html_type'); ?>; charset=<?php bloginfo('charset'); ?>" />

Any ideas guys???

If you use event attributes (instead of external, unobtrusive scripting, which is what is recommended) you should state which scripting language you use. For a <script> tag it's not necessary, since it's stated in the required type attribute. But for attributes containing script code you should explain what language it is.

You do this with the Content-Script-Type HTTP header (or a meta equivalent):

<meta http-equiv="Content-Script-Type" content="text/javascript"/>

I don't know of any browser that doesn't assume JavaScript for undeclared script code, but the HTML spec says you should be explicit about it.

Using external unobtrusive scripting would be much better, though.

It's the same sort of issue. If you use style attributes instead of external CSS style sheets (<link rel="stylesheet".../>) or internal style sheets (<style>...</style> tags) you should declare the style sheet language with the Content-Style-Type HTTP header or meta equivalent.

<meta http-equiv="Content-Style-Type" content="text/css"/>

Edit:

You posted while I typed.
I'll leave my explanation, though, since it may help someone else who stumbles over the same problem.
