| <p>HTML and XHTML documents that use frames </p> | ||
| </section><section id="description"><h2>Description</h2> | ||
| <p>The objective of this technique is to demonstrate how framesets can be used to group | ||
| blocks of repeated material. Since most user agents and assistive technology provide a | ||
| way to navigate from frame to frame, using frames to organize elements can provide a | ||
| mechanism for easily bypassing blocks of repeated content. If the site uses framesets, | ||
| organize the blocks of content into separate frames. Make certain that the repeated | ||
| blocks of content appear in the same frame within the frameset of each Web page. In | ||
| addition, each frame element must have a title attribute to describe the content of the | ||
| frame. When frames are properly titled, users can use frame navigation to easily | ||
| navigate between blocks of content.</p> | ||
| <p>This technique is appropriate when framesets are already used to organize the content | ||
| of the page; other techniques are preferred for pages that are not already using | ||
| framesets, because many people using assistive technology have trouble with frames . An | ||
| advisory technique about using noframes is available in <a href="https://www.w3.org/WAI/WCAG21/Understanding/non-text-content">Success Criterion 1.1.1</a>. </p> | ||
| <p>In HTML5 the <code class="el">frame</code> element is marked as obsolete.</p> | ||

| <section class="example"> | ||
|
|
||
| <p>The following example shows the use of two frames to organize content. The source | ||
| of the first frame is the Web page, navigation.html, which contains the HTML for the | ||
| navigation. This frame has a title attribute which identifies it as a navigation | ||
| bar. The second frame contains the main content of the site as indicated by the | ||
| source parameter of main.html and the title attribute, "Main News Content" which | ||
| identifies its function.</p> | ||
|
|
||
| <pre xml:space="preserve"><frameset cols="20%, *"> | ||
| <frame src="navigation.html" name="navbar" title="Navigation Bar" /> | ||
| <frame src="main.html" name="maincontent" title="Main News Content" /> | ||
| <noframes> | ||
| <p>View <a href="noframe.html">no frame version</a>.</p> | ||
| </noframes> | ||
| </frameset> </pre> | ||
