This code on the forum home is giving off XHTML errors...

<!-- Everywhere Sidebar starts-->
<style>
#content_container{width:100%;float:left;margin-right:-205px;padding:10px 0}
#content_container.contentright{float:right;margin-right:0;margin-left:-205px}
#sidebar_container{float:right;width:185px;padding:17px 0;margin-bottom:3em}
#sidebar_button{display:block;margin-top:40px;float:left;margin-left:-28px;_margin:40px 0 0 0;_display:inline-block}
#sidebar_button{float:right;margin-right:-28px}
.sidebarleft #sidebar_button{float:left;margin-left:-28px;margin-right:0}
</style>

The error are:

 Line 2777, Column 7: required attribute "type" not specified
<style>

The attribute given above is required for an element that you've used, but you have omitted it. For instance, in most HTML and XHTML document types the "type" attribute is required on the "script" element and the "alt" attribute is required for the "img" element.

Typical values for type are type="text/css" for <style> and type="text/javascript" for <script>.

 Line 2777, Column 7: document type does not allow element "style" here
<style>

The element named above was found in a context where it is not allowed. This could mean that you have incorrectly nested elements -- such as a "style" element in the "body" section instead of inside "head" -- or two elements that overlap (which is not allowed).

One common cause for this error is the use of XHTML syntax in HTML documents. Due to HTML's rules of implicitly closed elements, this error can create cascading effects. For instance, using XHTML's "self-closing" tags for "meta" and "link" in the "head" section of a HTML document may cause the parser to infer the end of the "head" section and the beginning of the "body" section (where "link" and "meta" are not allowed; hence the reported error).
