<h2 id="introduction">Introduction</h2>
<p>The Material Design Lite (MDL) <strong>grid</strong> component is a simplified method for laying out content for multiple screen sizes. It reduces the usual coding burden required to correctly display blocks of content in a variety of display conditions.</p>
<p>The MDL grid is defined and enclosed by a container element. A grid has 12 columns in the desktop screen size, 8 in the tablet size, and 4 in the phone size, each size having predefined margins and gutters. Cells are laid out sequentially in a row, in the order they are defined, with some exceptions:</p>
<ul>
<li>If a cell doesn&#39;t fit in the row in one of the screen sizes, it flows into the following line.</li>
<li>If a cell has a specified column size equal to or larger than the number of columns for the current screen size, it takes up the entirety of its row.</li>
</ul>
<p>You can set a maximum grid width, after which the grid stays centered with padding on either side, by setting its <code>max-width</code> CSS property.</p>
<p>Grids are a fairly new and non-standardized feature in most user interfaces, and provide users with a way to view content in an organized manner that might otherwise be difficult to understand or retain. Their design and use is an important factor in the overall user experience.</p>
<h3 id="to-include-an-mdl-grid-component-">To include an MDL <strong>grid</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 grid&#39;s cells. Style the div as desired (colors, font size, etc.).</p>
<pre><code class="lang-html">&lt;div&gt;
&lt;/div&gt;
</code></pre>
<p>&nbsp;2. Add the <code>mdl-grid</code> MDL class to the div using the <code>class</code> attribute.</p>
<pre><code>&lt;div class=&quot;mdl-grid&quot;&gt;
&lt;/div&gt;
</code></pre><p>&nbsp;3. For each cell, code one &quot;inner&quot; div, including the text to be displayed.</p>
<pre><code class="lang-html">&lt;div class=&quot;mdl-grid&quot;&gt;
  &lt;div&gt;Content&lt;/div&gt;
  &lt;div&gt;goes&lt;/div&gt;
  &lt;div&gt;here&lt;/div&gt;
&lt;/div&gt;
</code></pre>
<p>&nbsp;4. Add the <code>mdl-cell</code> class and an <code>mdl-cell--COLUMN-col</code> class, where COLUMN specifies the column size for the cell, to the &quot;inner&quot; divs using the <code>class</code> attribute.</p>
<pre><code class="lang-html">&lt;div class=&quot;mdl-grid&quot;&gt;
  &lt;div class=&quot;mdl-cell mdl-cell--4-col&quot;&gt;Content&lt;/div&gt;
  &lt;div class=&quot;mdl-cell mdl-cell--4-col&quot;&gt;goes&lt;/div&gt;
  &lt;div class=&quot;mdl-cell mdl-cell--4-col&quot;&gt;here&lt;/div&gt;
&lt;/div&gt;
</code></pre>
<p>&nbsp;5. Optionally add an <code>mdl-cell--COLUMN-col-DEVICE</code> class, where COLUMN specifies the column size for the cell on a specific device, and DEVICE specifies the device type.</p>
<pre><code class="lang-html">&lt;div class=&quot;mdl-grid&quot;&gt;
  &lt;div class=&quot;mdl-cell mdl-cell--4-col mdl-cell--8-col-tablet&quot;&gt;Content&lt;/div&gt;
  &lt;div class=&quot;mdl-cell mdl-cell--4-col mdl-cell--8-col-tablet&quot;&gt;goes&lt;/div&gt;
  &lt;div class=&quot;mdl-cell mdl-cell--4-col mdl-cell--8-col-tablet&quot;&gt;here&lt;/div&gt;
&lt;/div&gt;
</code></pre>
<p>The grid component is ready for use.</p>
<h4 id="examples">Examples</h4>
<p>A grid with five cells of column size 1.</p>
<pre><code class="lang-html">&lt;div class=&quot;mdl-grid&quot;&gt;
  &lt;div class=&quot;mdl-cell mdl-cell--1-col&quot;&gt;CS 1&lt;/div&gt;
  &lt;div class=&quot;mdl-cell mdl-cell--1-col&quot;&gt;CS 1&lt;/div&gt;
  &lt;div class=&quot;mdl-cell mdl-cell--1-col&quot;&gt;CS 1&lt;/div&gt;
  &lt;div class=&quot;mdl-cell mdl-cell--1-col&quot;&gt;CS 1&lt;/div&gt;
  &lt;div class=&quot;mdl-cell mdl-cell--1-col&quot;&gt;CS 1&lt;/div&gt;
&lt;/div&gt;
</code></pre>
<p>A grid with three cells, one of column size 6, one of column size 4, and one of column size 2.</p>
<pre><code class="lang-html">&lt;div class=&quot;mdl-grid&quot;&gt;
  &lt;div class=&quot;mdl-cell mdl-cell--6-col&quot;&gt;CS 6&lt;/div&gt;
  &lt;div class=&quot;mdl-cell mdl-cell--4-col&quot;&gt;CS 4&lt;/div&gt;
  &lt;div class=&quot;mdl-cell mdl-cell--2-col&quot;&gt;CS 2&lt;/div&gt;
&lt;/div&gt;
</code></pre>
<p>A grid with three cells of column size 6 that will display as column size 8 on a tablet device.</p>
<pre><code class="lang-html">&lt;div class=&quot;mdl-grid&quot;&gt;
  &lt;div class=&quot;mdl-cell mdl-cell--6-col mdl-cell--8-col-tablet&quot;&gt;CS 6 (8 on tablet)&lt;/div&gt;
  &lt;div class=&quot;mdl-cell mdl-cell--6-col mdl-cell--8-col-tablet&quot;&gt;CS 6 (8 on tablet)&lt;/div&gt;
  &lt;div class=&quot;mdl-cell mdl-cell--6-col mdl-cell--8-col-tablet&quot;&gt;CS 6 (8 on tablet)&lt;/div&gt;
&lt;/div&gt;
</code></pre>
<p>A grid with four cells of column size 2 that will display as column size 4 on a phone device.</p>
<pre><code class="lang-html">&lt;div class=&quot;mdl-grid&quot;&gt;
  &lt;div class=&quot;mdl-cell mdl-cell--2-col mdl-cell--4-col-phone&quot;&gt;CS 2 (4 on phone)&lt;/div&gt;
  &lt;div class=&quot;mdl-cell mdl-cell--2-col mdl-cell--4-col-phone&quot;&gt;CS 2 (4 on phone)&lt;/div&gt;
  &lt;div class=&quot;mdl-cell mdl-cell--2-col mdl-cell--4-col-phone&quot;&gt;CS 2 (4 on phone)&lt;/div&gt;
  &lt;div class=&quot;mdl-cell mdl-cell--2-col mdl-cell--4-col-phone&quot;&gt;CS 2 (4 on phone)&lt;/div&gt;
&lt;/div&gt;
