If people commented their CSS it would help others a lot. A comment is to explain why or how you have done the styling. It would help them as well when they go back to the styles two years later and can't remember what they were trying to do. Some things you have done are likely to be obvious but others may be there for reasons which might not stand out. CSS comments are done like this:
/* this is a CSS comment which describes the next style section as being to make parts of a paragraph red */
.redtext {
color:red;
}
You just put a /* at the begging of the comment and */ at the end. In a proper CSS editor the comment will be a different colour to the code to make it stand out.
Anything inside a comment is ignored by the browser. If you want to remove some CSS from a Web page temporarily just make it a comment by wrapping it in /* and */.
