        <p>Set a style of the whole map during the map instantiation</p>
    </div>
    <p>This example shows how to set a map style during the map loading. The vector layer uses the 'normal.day' style by default, the style
      can be changed to the user defined while the map is loading.

    <h3>Code</h3>
    <p>The code below created a new <codeph>H.map.Style</codeph> instance that loads and parses the user's style 'dark.yaml'. After that
      the style is set on the current vector provider.
