Adjacent sibling selectors
Adjacent sibling selectors will pick the sibling right away following a component.
As an example,
Windows 7 Key, you could wish to target an <h3> aspect, but only <h3> elements that right away follow an <h2> factor. This is a commonly used instance,
Office 2007 Enterprise, as it has a real-world application. There is often too much space between <h2> and <h3> elements when they appear quickly after each other. The code would be:
<body>
<h2>Heading 2 <em>text</em></h2>
<h3>Heading 3 text</h3>
<p>This is <em>text</em> and more <strong>text</strong></p>
</body>
The document tree would be:
Using the following rule,
Office 2007 Key, you can target any <h3> that follows an <h2>:
h2 + h3 margin: -1em;
Adjacent sibling selectors also work for inline elements such as <em> and <strong>
Using the subsequent rule,
Office 2007 Keygen, you can target <strong> text that follows <em> text:
em + strong color: blue;
Adjacent sibling selectors are not supported by Windows Internet Explorer 5,
Microsoft Office 2007 Professional, 5.5 and 6, but are supported by most other standards-compliant browsers.
