Prototype: GOV.UK template with spinner

README.md

Sharing a piece of work done as part of a prototype that relies on a mapping service that takes up to 2 minutes to respond.

This is an attempt at a loading page for that prototype.

Original spinner code from: http://projects.lukehaas.me/css-loaders/

The only changes made to it are to match GOV.UK colours, we are also using the govuk_template.

The CSS3 spinning animation degrades to "Loading..." text for older browsers.

<main id="content">
  <h1 class="heading-xlarge">Please wait while we generate your report...</h1>
  <p class="lede">This could take up to 2 minutes.</p>
  <div class="loader">Loading...</div>
</main>
