How to select classes with spaces

Question

How do I select a class like class=\"boolean optional\" ?

I have tried this:

.boolean optional {CSS}

.boolean_optional {CSS}
         


        

Answer 1

Classes will never actually have spaces in their name. In your example, that is actually two classes; boolean and optional.

to apply style to an element that has both of those classes, the construct is

.boolean.optional {
 /* CSS */
}

However, IE6 is known to have some issues with this. See this link for more details on known quirks.
