Mozilla CSS3 and the W3C validation

Your main stylesheets should have the standards version only. Create [stylesheet-name].[browser]fix.css for any browser-specific fixes. (e.g. "main.css" has "main.iefix.css", "main.mozfix.css", etc.) Then, as browsers fix things, you can just reduce/remove the fix files whilst leaving your main stylesheets untouched.
