Ask for advice

Dear sirs, I'd appreciate you were so kind to give me some advice about :

1- I intend to make a web page based on a CSS page compounded by three columns (embedded style sheet) No html. Only CSS from Glish.com.-
   I've tried to validate it directly from your place but receive "parse error".

Maybe it happens because  submitted the whole page. Including the headings: title, meta tags with keywords and descriptions.

Could you please let me know which would be the parse errors? 
I also received a note which reads: Use valid html. 

Thanks in advance

J. Pizarro
