CSS: Hover one element, effect for multiple elements?

Solution 1:

You don't need JavaScript for this.

Some CSS would do it. Here is an example:

<html>
  <style type="text/css">
    .section { background:#ccc; }
    .layer { background:#ddd; }
    .section:hover img { border:2px solid #333; }
    .section:hover .layer { border:2px solid #F90; }
  </style>
</head>
<body>
  <div class="section">
    <img src="myImage.jpg" />
    <div class="layer">Lorem Ipsum</div>
  </div>
</body>
</html>

Solution 2:

This worked for me in Firefox and Chrome and IE8...

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd"> 
<html>
    <head>
        <style type="text/css">
        div.section:hover div.image, div.section:hover div.layer {
            border: solid 1px red;
        }
        </style>
    </head>
    <body>
        <div class="section">
            <div class="image"><img src="myImage.jpg" /></div>
            <div class="layer">Lorem Ipsum</div>
        </div>
    </body>
</html>

... you may want to test this with IE6 as well (I'm not sure if it'll work there).

Solution 3:

I think the best option for you is to enclose both divs by another div. Then you can make it by CSS in the following way:

<html>
<head>
<style>
  div.both:hover .image { border: 1px solid blue }
  div.both:hover .layer { border: 1px solid blue }
</style>
</head>

<body>
<div class="section">

<div class="both">
  <div class="image"><img src="myImage.jpg" /></div>
  <div class="layer">Lorem Ipsum</div>
</div>

</div>
</body>
</html>
