Sorry to bother you with trivial questions, but I have been away from Web design for a while, and I did a search of the site before posting, in case I could answer my own question.
As I recollect, in early HTML it didn't matter whether you used upper or lower case when writing your HTML code, but I have a strong feeling that lower case is the standard in more recent versions ... or is it in CSS where lower case is preferred?
In summary:
1. which is preferred in HTML/XHTML - uppercase or lowercase?
2. which is preferred in external style sheets - uppercase or lowercase?
Many thanks, James
