<p>The <code>.container</code> class centers content on the page and restricts it to a maximum width.</p>
</div></code></pre>
<p>Kraken also includes a simple, mobile-first grid system built with CSS Grid.</p>
<p>It's designed to be a starting point you can modify and build on (or delete altogether) depending on your project. Modify as needed.</p>
<h3 id="fraction-based-layouts">Fraction-based layouts</h3>
<p>Kraken uses fraction-based grids, because it makes the math of grid-based layouts easier.</p>
<p>To create a grid, add a <code><div></code> with a <code>.row</code> class. You can create grids within a row by creating <code><div></code> elements with the <code>.grid-*</code> class.</p>
<div class="row">
<div class="grid-third grid-highlight">.grid-third</div>
<div class="grid-two-thirds grid-highlight">.grid-two-thirds</div>

<h2 id="typography">Typography</h2>
<p>Kraken uses relative sizing (ems and %, not pixels) for everything.</p>
<p>The <code>body</code> has a base <code>font-size</code> of <code>100%</code>, which is <code>16px</code> on browsers with default font settings. All other sizes are in ems. Changing the <code>font-size</code> on the <code>body</code> element will adjust the typographical scale for the entire site.</p></p>

<p><em>Because Kraken uses relative sizing, you should always apply <code>.text-large</code> and <code>.text-small</code> classes to a <code>span</code> element and not directly to a <code>p</code>.

<h3 id="visibility">Visibility</h3>
<p>Hide content using the <code>[hidden]</code> attribute.</p>
<pre><code class="language-html"><div hidden>This is removed from the markup.</div></code></pre>
<p>If you have text that you don't want displayed on screen, but that should still be in the markup for screen readers (for example, a search form label), simply apply the <code>.visually-hidden</code> class.</p></p>
<pre><code class="language-html"><form>
<label class="visually-hidden">Search this site</label>
<input type="text" placeholder="Search this site...">
<input type="submit">
</form></code></pre>
<p>For visually hidden content that should become visible on focus (such as a <a href="http://webaim.org/techniques/skipnav/">skip nav link</a> for sighted users navigating by keyboard), add the <code>.focusable</code> class.</p>
<pre><code class="language-html"><a class="visually-hidden focusable" href="#main">Skip to content</a></code></pre>
<h2 id="tabindex--focus-styles">Tabindex & Focus Styles</h2>
<p>Focusable elements should <em>always</em> have <code>:focus</code> styles on them. You can customize them, but don't remove them altogether.</p>
<p>If you need to programmatically add focus to an element that's not normally focusable (like a <code>div</code>), you need to give it a <code>tabindex</code> attribute of <code>-1</code>. However, this also applies <code>:focus</code> styles, which are likely not desired or needed in these rare edge cases.</p>
<p>Kraken removes the default outline from items with <code>[tabindex="-1"]</code>.</p>
