Also, HTML keywords such as POST do not need to be quoted.
15 and 60 are not going to be used in a string context, and should not be quoted. The browser will read it anyway, but it is less clear. Save quotes for strings that are used for their string value, such as name, value, href, action, and src.attributes.
I disagree with the above two statements. As part of the XHTML 1.0 standard attribute values are all to be double quoted, it is a good habit to get into. Not quoting numbers is a good habit in Perl or other programming languages, but in an ML they are strings regardless unless you are going to put another data type tag around them designating them as such in which case they cease to be attribute values.
Will it work in most browsers, sure, but that doesn't mean the move to standards compliant coding should be contradicted.
