<h1>stuQuery hexmap</h1>
<p>This is a simple HTML-based hexmapping library that makes use of <a href="index.html">stuQuery</a>. Being created from simple HTML elements, it is easy to style the hexes with CSS. Each hex is accessible via the keyboard too.</p>
<p>As HTML is based on rectangles, we've had to create hexagons using CSS's <code>clip-path</code>. We've simulated a border on each hexagon by nesting two elements and setting the <code>border-color</code> by using <code>background-color</code> on the outer element and <code>border-width</code> by using <code>margin</code> on the inner element</code>.</p>
<p>Make sure to include the relevant CSS and Javascript files in your HTML page:</p>

<h2><a href="#basic">Basic hex map</a></h2>
<p>Let's create a simple hex map. We define the hex map by embedding some <a href="https://odileeds.org/projects/hexmaps/hexjson">HexJSON</a> (that way the raw data is visible if Javascript fails).</p>
