CSS comments

1. CSS comments stop the CSS style rules written within a CSS stylesheet, from being processed while displaying an HTML document in the browser.

2. CSS comments start with "/*" and end with "*/". You can use this both

3. CSS comments can be placed anywhere in a CSS stylesheet.

4. CSS comment can not be nested, i.e. a comment can not hold another comment within it.

5. You can use HTML style comment ( "" ) in a CSS stylesheet also. But it does not have anything to do with CSS comments. This is allowed just to hide style rules from pre-HTML 3.2 user agents ( e.g. browsers ).
