This is a simple HTML-based hexmapping library that makes use of stuQuery. Being created from simple HTML elements, it is easy to style the hexes with CSS. Each hex is accessible via the keyboard too.
As HTML is based on rectangles, we've had to create hexagons using CSS's clip-path. We've simulated a border on each hexagon by nesting two elements and setting the border-color by using background-color on the outer element and border-width by using margin on the inner element.
