<p>The Material Design Lite (MDL) <strong>footer</strong> component is a comprehensive container intended to present a substantial amount of related content in a visually attractive and logically intuitive area. Although it is called &quot;footer&quot;, it may be placed at any appropriate location on a device screen, either before or after other content.</p>
<p>An MDL footer component takes two basic forms: <em>mega-footer</em> and <em>mini-footer</em>. As the names imply, mega-footers contain more (and more complex) content than mini-footers. A mega-footer presents multiple sections of content separated by horizontal rules, while a mini-footer presents a single section of content. Both footer forms have their own internal structures, including required and optional elements, and typically include both informational and clickable content, such as links.</p>
<p>Footers, as represented by this component, are a fairly new feature in user interfaces, and allow users to view discrete blocks of content in a coherent and consistently organized way. Their design and use is an important factor in the overall user experience.</p>
<h3 id="to-include-an-mdl-mega-footer-component-">To include an MDL <strong>mega-footer</strong> component:</h3>
<p>&nbsp;1a. Code a <code>&lt;footer&gt;</code> element. Inside the footer, include one <code>&lt;div&gt;</code> element for each content section, typically three: <em>top</em>, <em>middle</em>, and <em>bottom</em>.</p>
<pre><code class="lang-html">&lt;footer&gt;
  &lt;div&gt;
  ...
  &lt;/div&gt;
  &lt;div&gt;

  ...
  &lt;/div&gt;
&lt;/footer&gt;
</code></pre>
<p>&nbsp;1b. Add the appropriate MDL classes to the footer and divs using the <code>class</code> attribute.</p>
<pre><code class="lang-html">&lt;footer class=&quot;mdl-mega-footer&quot;&gt;
  &lt;div class=&quot;mdl-mega-footer__top-section&quot;&gt;
  ...
  &lt;/div&gt;
