<map-style>

The <map-style> element allows map authors to embed CSS into map layers. The CSS can be used to style the geometry of the layer using <map-span>, and by setting the class attribute to the child elements of the geometry.

note

All the Demo's on the documentation pages contain a "CSS" tab which adds the CSS using the <map-style> element dynamically.

    <map-feature>
      <map-featurecaption>Polygon</map-featurecaption>
      <!-- Setting the geometry coordinates to gcrs, as the default is pcrs -->
