<h2 id="introduction">Introduction</h2>
<p>The Material Design Lite (MDL) <strong>card</strong> component is a user interface element representing a virtual piece of paper that contains related data &mdash; such as a photo, some text, and a link &mdash; that are all about a single subject.</p>
<p>Cards are a convenient means of coherently displaying related content that is composed of different types of objects. They are also well-suited for presenting similar objects whose size or supported actions can vary considerably, like photos with captions of variable length. Cards have a constant width and a variable height, depending on their content.</p>
<p>Cards are a fairly new feature in user interfaces, and allow users an access point to more complex and detailed information. Their design and use is an important factor in the overall user experience. See the card component&#39;s <a href="http://www.google.com/design/spec/components/cards.html">Material Design specifications page</a> for details.</p>
<h3 id="to-include-an-mdl-card-component-">To include an MDL <strong>card</strong> component:</h3>
<p>&nbsp;1. Code a <code>&lt;div&gt;</code> element; this is the &quot;outer&quot; container, intended to hold all of the card&#39;s content.</p>
<pre><code class="lang-html">&lt;div&gt;
&lt;/div&gt;
</code></pre>
<p>&nbsp;2. Inside the div, code one or more &quot;inner&quot; divs, one for each desired content block. A card containing a title, an image, some text, and an action bar would contain four &quot;inner&quot; divs, all siblings.</p>
<pre><code class="lang-html">&lt;div&gt;
  &lt;div&gt;
  ...
  &lt;/div&gt;
  &lt;div&gt;
  ...
  &lt;/div&gt;
  &lt;div&gt;
  ...
  &lt;/div&gt;
  &lt;div&gt;
  ...
  &lt;/div&gt;
&lt;/div&gt;
</code></pre>
<p>&nbsp;3. Add one or more MDL classes, separated by spaces, to the &quot;outer&quot; div and the &quot;inner&quot; divs (depending on their intended use) using the <code>class</code> attribute.</p>
<pre><code class="lang-html">&lt;div class=&quot;mdl-card&quot;&gt;
  &lt;div class=&quot;mdl-card__title&quot;&gt;
  ...
  &lt;/div&gt;
  &lt;div class=&quot;mdl-card__media&quot;&gt;
  ...
  &lt;/div&gt;
  &lt;div class=&quot;mdl-card__supporting-text&quot;&gt;
  ...
  &lt;/div&gt;
  &lt;div class=&quot;mdl-card__actions&quot;&gt;
  ...
  &lt;/div&gt;
&lt;/div&gt;
</code></pre>
<p>&nbsp;4. Add content to each &quot;inner&quot; div, again depending on its intended use, using standard HTML elements and, optionally, additional MDL classes.</p>
<pre><code class="lang-html">&lt;div class=&quot;mdl-card&quot;&gt;
  &lt;div class=&quot;mdl-card__title&quot;&gt;
    &lt;h2 class=&quot;mdl-card__title-text&quot;&gt;title Text Goes Here&lt;/h2&gt;
  &lt;/div&gt;
  &lt;div class=&quot;mdl-card__media&quot;&gt;
    &lt;img src=&quot;photo.jpg&quot; width=&quot;220&quot; height=&quot;140&quot; border=&quot;0&quot; alt=&quot;&quot; style=&quot;padding:20px;&quot;&gt;
  &lt;/div&gt;
  &lt;div class=&quot;mdl-card__supporting-text&quot;&gt;
    This text might describe the photo and provide further information, such as where and
    when it was taken.
  &lt;/div&gt;
  &lt;div class=&quot;mdl-card__actions&quot;&gt;
    &lt;a href=&quot;(URL or function)&quot;&gt;Related Action&lt;/a&gt;
  &lt;/div&gt;
&lt;/div&gt;
</code></pre>
<p>The card component is ready for use.</p>
