It's primarily used with the <code><link></code> and <code><a></code> tags to provide context and meaning to links.</p> <h2>Common Uses of the `rel` Attribute</h2> <h3>Stylesheets</h3> <p>The most common use is linking stylesheets: <code><link rel="stylesheet" href="styles.css"></code>. This clearly indicates the linked file is a stylesheet.</p> <h3>Alternate Stylesheets</h3> <p>You can define multiple stylesheets using <code>rel="alternate stylesheet"</code>. However, browser support for easily switching between these is limited. A JavaScript-based solution is often necessary for user selection.</p> <pre class="brush:php;toolbar:false"><code> <link href="main.css" media="screen" rel="stylesheet" type="text/css"> <link rel="alternate stylesheet" title="Higher Contrast" href="contrast.css" type="text/css" media="screen"> <link rel="alternate stylesheet" title="Gratuitous CSS" href="hot.css" type="text/css" media="screen"> </code>
