Don’t forget to comment your css

As a beginner, you may tend to think that you shouldn’t waste your time commenting your css and there are many designers who think like that.

But what happens if you have to modify an uncommented css of about 3000 lines, that you worked on some 2-3years ago? Working on a bulky css that has no comments is only trouble.

You don’t have to comment all your styles, you may atleast separate them into large chunks, like
/*-------------------- header ------------*/ , /*----------footer----------*/.
So the next time you are to modify the css, you wont lose time on trying to figure out which class or id you have to modify.
