CSS selectors - how to select 'for' in CSS?

Question

I\'m using jQuery validation.

When for is now valid, validator is creating those:

<         


        

Answer 1

Any attribute can be selected with CSS or jQuery using the [] notation. CSS applies to any XML-like syntax, not just HTML -- it doesn't know (or care) what attributes are "valid" as long as the structure is well-formed.

.error[for='username'] {

}

or for a "starts with"

.error[for^='userprefix'] {

}
