1. Get the code

Using cdn

The easiest way to get started. Drop this into your page's head section and you're good to go.
<link href="//cdn.rawgit.com/eskilfogelstrom/sigrid/1.0.0/dist/sigrid.min.css" rel="stylesheet" type="text/css">

Using bower

You can also get the latest release using bower. This release contains source files as well as the compiled CSS.
bower install sigrid --save

2. Create a row with some columns

Next just drop in the sigrid classes in your HTML.

<div class="row">
  <div class="col col--4">...</div>
  <div class="col col--4">...</div>
  <div class="col col--4">...</div>
</div>
