<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'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> 1. Code a <code><div></code> element; this is the "outer" container, intended to hold all of the grid's cells. Style the div as desired (colors, font size, etc.).</p> <pre><code class="lang-html"><div> </div> </code></pre> <p> 2. Add the <code>mdl-grid</code> MDL class to the div using the <code>class</code> attribute.</p> <pre><code><div class="mdl-grid"> </div> </code></pre><p> 3. For each cell, code one "inner" div, including the text to be displayed.</p> <pre><code class="lang-html"><div class="mdl-grid"> <div>Content</div> <div>goes</div> <div>here</div> </div> </code></pre> <p> 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 "inner" divs using the <code>class</code> attribute.</p> <pre><code class="lang-html"><div class="mdl-grid"> <div class="mdl-cell mdl-cell--4-col">Content</div> <div class="mdl-cell mdl-cell--4-col">goes</div> <div class="mdl-cell mdl-cell--4-col">here</div> </div> </code></pre> <p> 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"><div class="mdl-grid"> <div class="mdl-cell mdl-cell--4-col mdl-cell--8-col-tablet">Content</div> <div class="mdl-cell mdl-cell--4-col mdl-cell--8-col-tablet">goes</div> <div class="mdl-cell mdl-cell--4-col mdl-cell--8-col-tablet">here</div> </div> </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"><div class="mdl-grid"> <div class="mdl-cell mdl-cell--1-col">CS 1</div> <div class="mdl-cell mdl-cell--1-col">CS 1</div> <div class="mdl-cell mdl-cell--1-col">CS 1</div> <div class="mdl-cell mdl-cell--1-col">CS 1</div> <div class="mdl-cell mdl-cell--1-col">CS 1</div> </div> </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"><div class="mdl-grid"> <div class="mdl-cell mdl-cell--6-col">CS 6</div> <div class="mdl-cell mdl-cell--4-col">CS 4</div> <div class="mdl-cell mdl-cell--2-col">CS 2</div> </div> </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"><div class="mdl-grid"> <div class="mdl-cell mdl-cell--6-col mdl-cell--8-col-tablet">CS 6 (8 on tablet)</div> <div class="mdl-cell mdl-cell--6-col mdl-cell--8-col-tablet">CS 6 (8 on tablet)</div> <div class="mdl-cell mdl-cell--6-col mdl-cell--8-col-tablet">CS 6 (8 on tablet)</div> </div> </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"><div class="mdl-grid"> <div class="mdl-cell mdl-cell--2-col mdl-cell--4-col-phone">CS 2 (4 on phone)</div> <div class="mdl-cell mdl-cell--2-col mdl-cell--4-col-phone">CS 2 (4 on phone)</div> <div class="mdl-cell mdl-cell--2-col mdl-cell--4-col-phone">CS 2 (4 on phone)</div> <div class="mdl-cell mdl-cell--2-col mdl-cell--4-col-phone">CS 2 (4 on phone)</div> </div> </code></pre> <h2 id="configuration-options">Configuration options</h2> <p>The MDL CSS classes apply various predefined visual enhancements and behavioral effects to the grid.
