The message isn't optimally clear since it does not explicitly refer to the fact that at this phase, HTML and not CSS being processed. In lexical analysis of HTML markup, "<!-" was encountered, followed by a line break. (That's what '"\n" (10)' refers to, somewhat obscurely: "\n" is a notation for a line break in several programming languages and 10 is the code number of a character that is used as line break character. Neither of these notations is an HTML notation or a CSS notation!) The construct, "<!-" followed by a line break, is not allowed in HTML. In practice, you meant to write "<!--" but forgot the other "-". On the other hand, using <style type="text/css"><!-- and --></style> instead of simple <style type="text/css"> and </style> has been pointless for years, and it's also risky, as you've seen. "No style sheet found" apparently means that after this error, the HTML parser used by "CSS Validator" does not try to extract the style sheet included in the <style> element for analysis as CSS code. The message is misleading, however, since the program may well detect and analyze _other_ style sheets in the document - in other <style> elements or in style="..." attributes - and yet it issues "No style sheet found" prominently and centered at the end of its report, _after_ issuing error messages about those style sheets. -- Jukka "Yucca" Korpela, http://www.cs.tut.fi/~jkorpela/
