CSS Selector that applies to elements with two classes

Question

Is there a way to select an element with CSS based on the value of the class attribute being set to two specific classes. For example, let\'s say I have 3 divs:

Answer 1

Chain both class selectors (without a space in between):

.foo.bar {
    /* Styles for element(s) with foo AND bar classes */
}

---

If you still have to deal with ancient browsers like IE6, be aware that it doesn't read chained class selectors correctly: it'll only read the last class selector (.bar in this case) instead, regardless of what other classes you list.

To illustrate how other browsers and IE6 interpret this, consider this CSS:

* {
    color: black;
}

.foo.bar {
    color: red;
}

Output on supported browsers is:

Hello Foo
       
Hello World
 
Hello Bar
       

Output on IE6 is:

Hello Foo
       
Hello World
 
Hello Bar
       

Footnotes:

• Supported browsers:
  1. Not selected as this element only has class foo.
  2. Selected as this element has both classes foo and bar.
  3. Not selected as this element only has class bar.
     
     
• IE6:
  1. Not selected as this element doesn't have class bar.
  2. Selected as this element has class bar, regardless of any other classes listed.
