CSS Selector that applies to elements with two classes


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:

<div class="foo">Hello Foo</div>
<div class="foo bar">Hello World</div>
<div class="bar">Hello Bar</div>

What CSS could I write to select ONLY the second element in the list, based on the fact that it is a member of both the foo AND bar classes?


Solution

  • 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 Internet Explorer 6, 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 snippet:

    * {
      color: black;
    }
    
    .foo.bar {
      color: red;
    }
    <div class="foo">1. Hello Foo</div>
    <div class="foo bar">2. Hello World</div>
    <div class="bar">3. Hello Bar</div>
