Allows customisation of the loading icon used in JavaScript mode. Receives the default SVG markup:

<svg version="1.1" class="age-gate-loading-icon" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" x="0px" y="0px" width="40px" height="40px" viewBox="0 0 40 40" enable-background="new 0 0 40 40" xml:space="preserve">

  <path d="M26.013,10.047l1.654-2.866c-2.198-1.272-4.743-2.012-7.466-2.012h0v3.312h0 C22.32,8.481,24.301,9.057,26.013,10.047z">
    <animateTransform attributeType="xml"
      attributeName="transform"
      type="rotate"
      from="0 20 20"
      to="360 20 20"
      dur="0.5s"
      repeatCount="indefinite"/>
  </path>
</svg>

Which would normally output:

As this is an SVG, it’s appearance can be altered with CSS:

.age-gate-loading-icon {
    fill: green;
}
