Your script is not XHTML 1.0 strict!

Hi,
I ran your test on my site and all is well it passed validation.
Then inserted your script!

I ran your test on style sheets and it passed validation.
Then inserted your script!

....Then I ran your test on my site and it failed!

Your script is wrong... Can you see the error?

<p>
 <a href="http://jigsaw.w3.org/css-validator/">
  <img style="border:0;width:88px;height:31px"
       src="http://jigsaw.w3.org/css-validator/images/vcss" 
       alt="Valid CSS!">
 </a>
</p>

Should be;
<p>
 <a href="http://jigsaw.w3.org/css-validator/">
  <img style="border:0;width:88px;height:31px"
       src="http://jigsaw.w3.org/css-validator/images/vcss" 
       alt="Valid CSS!" />
 </a>
