Church theme validation error help

[paulac]

I have a few validation errors on the Church theme I've done for a client:

Line 198 is from the Featured Content Gallery - I've tried several fixes that didn't solve it and have addressed it on their forum but if anyone has new ideas, please share. I'm sure I'm not alone.

# Line 198, Column 25: document type does not allow element "style" here

<style type="text/css">
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).

The rest are from the header.php and footer.php:

# Line 580, Column 7: end tag for "div" omitted, but OMITTAG NO was specified

</body>
You may have neglected to close an element, or perhaps you meant to "self-close" an element, that is, ending it with "/>" instead of ">".

# Info Line 78: start tag was here
><div id="wrap">

# Error Line 580, Column 7: XML Parsing Error: Opening and ending tag mismatch: div line 78 and body
</body>

# Error Line 581, Column 7: XML Parsing Error: Opening and ending tag mismatch: body line 76 and html
</html>

# Error Line 581, Column 7: XML Parsing Error: Premature end of data in tag html line 2
</html>

I'm not all that experienced so any help is appreciated.
