I am converting my site from XHTML to HTML 5. I was checking my css and have a couple of questions:
1. my template came with a charset declaration at the top of the css and I wonder if that is correct. If it is what would be the correct charset for css on an HTML 5 site? I have UTF-8 on the html pages. I hope that is correct as well.
2. I am getting parsing errors on anything with a #: some examples: Parse Error [|#mainContent *|a:hover]
Parse Error [|#mainContent *|a]
Parse Error [|#mainContent *|td]
Parse Error [|#mainContent *|li]
Parse Error [|#mainContent *|p]
Parse Error [|#mainContent *|blockquote]

and anything with a . some examples:
Parse Error [|.quote]
Parse Error [|.imageLeft]
Parse Error [|.imageRight]

Thanks for the help.
