Customizing the loading screen

After updating map.apps, these modifications have to be applied again.

For example, a gif image is shown in the loading screen instead of the default animation by partially adjusting the index.html as described in the following:

<div id="splashScreen" class="splashScreen">
    <!-- Custom Loading Screen Content in the following line -->
    <div style="background-image: url(http://urltomy.gif);width:100%;height:100%;"></div>
    <div class="launch__title">
        <h4 class="splashHeader">
            <span class="launchLog"></span>
    <div class="launch__bundles">
        <p class="splashBundle">{nbsp}</p>

To show a custom loading screen for a single app, create a custom index.html file inside the app.
