CSS VALIDATOR

HI,

I was wondering if you can help me.  A web page I'm working (http:// 
mcsherryimages.co.uk/columns.html) on validates as XHTML, but when I  
try to validate the css I'm told to first validate the XML.

It says

Please, validate your XML document first!

Line 29

Column 111

Element type "input" must be followed by either attribute  
specifications, ">" or "/>".

and this is confusing because there already is a "/>".

What is to be done?

yours sincerely,



Andy Hull
