Yes, the Valid XHTML link code is not Valid with CSS.
I have tweaked almost every page on all my clients sites to put
validating code for both the HTML and CSS Validators.
Non Valid code in xml docuents with css:
<p>
<a href=""><img
src=""
alt="Valid XHTML 1.0 Strict" height="31" width="88" /></a>
</p>
Validating code through both the HTML and CSS Validators:
<p>
<a href=""><img
style="border:0;width:88px;height:31px"
src="" alt="Valid XHTML 1.0 Strict"
/></a>
<a href="">
<img style="border:0;width:88px;height:31px"
src=""
alt="Valid CSS!" />
</a>
</p>
Since I am always telling people that meeting "standards" is important,
I figure giving you code snippet to ad to the option for a page that
uses CSS as well can't hurt.

If I understand your argument correctly:

The validity of some markup is dependent on the DTD specified in the
Doctype, not the use (or otherwise) or a stylesheet.

The height and width attributes exist for all published versions of
XHTML, including Strict variants. Arguably, they belong there as they
describe the image rather then define its presentation (at least so
long as you use them to specify the actual pixel dimensions of the
image).

Except that when validating against the XHTML Strict DTD the image width
and height attributes cause a failed validation, since they are
not included in the DTD attribute list for images.
by putting them into a style statement the error goes away.

>>From #a_dtd_XHTML-1.0-Strict

<!ELEMENT img EMPTY>
<!ATTLIST img
%attrs;
src %URI; #REQUIRED
alt %Text; #REQUIRED
longdesc %URI; #IMPLIED
height %Length; #IMPLIED <
width %Length; #IMPLIED <
usemap %URI; #IMPLIED
ismap (ismap) #IMPLIED

Width and height are definitely there.

Then why does validating it give errors if they are not in a style element?
the errors came from the CSS validator, I know that the height and width
attributes caused the failure in validation.
