CSS: Hover one element, effect for multiple elements?

Css Problem Overview

I'm looking for a method for my hovering issue.

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

Now, both classes, image and layer, have borders. Both have different color for normal and hover. Is there way to make it, so if I hover layer class, both layer and image class hovering border color is active? And vise versa?

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>

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).

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>

This is not difficult to achieve, but you need to use the javascript onmouseover function. Pseudoscript:

<div class="section ">
<div class="image"><img src="myImage.jpg" onmouseover=".layer {border: 1px solid black;} .image {border: 1px solid black;}" /></div>
<div class="layer">Lorem Ipsum</div>
</div>

Use your own colors. You can also reference javascript functions in the mouseover command.

Solution 5 - Css

You'd need to use JavaScript to accomplish this, I think.

jQuery:

$(function(){
   $("#innerContainer").hover(
        function(){
            $("#innerContainer").css('border-color','#FFF');
            $("#outerContainer").css('border-color','#FFF');
        },
        function(){
            $("#innerContainer").css('border-color','#000');
            $("#outerContainer").css('border-color','#000');
        }
    );
});

Adjust the values and element id's accordingly :)

Solution 6 - Css

.section:hover > div {
  background-color: #0CF;
}

NOTE Parent element state can only affect a child's element state so you can use:

.image:hover + .layer {
  background-color: #0CF;
}
.image:hover {
  background-color: #0CF;
}

but you can not use

.layer:hover + .image {
  background-color: #0CF;
}

You can also do it like this. for example you have a link attached to another link and you want to show both at hovering at one you can do it simply by specifying each individual's functions then at once at hovering both.

.videoTitle:hover{
     color: #1270cf;
} 
.videoTitle:hover .copy{
     display: block;
}
