Themes manage all the style and the structure of your mobile app.
Themes own four folders:
Header folder contains:
<script src="js/jquery.mobile-1.3.1.min.js"></script>
<link href='http://fonts.googleapis.com/css?family=Meie+Script' rel='stylesheet' type='text/css'>
<link rel="stylesheet" type="text/css" href="js/jquery.mobile.structure-1.3.1.min.css" />
<link rel="stylesheet" type="text/css" href="theme/main.css" />
<script src="https://maps.googleapis.com/maps/api/js?sensor=false"></script>
In layout-templates folder, you can create custom templates for your layouts.
All the template's name have to finish by "-template.html"
In those templates, you simply write HTML contents.
To define "zone" (place where you can add gadget), you just have to add html class zone to a DIV
for exemple:
<div data-role="content">
<div id="zone-corps" class="zone">
</div>
</div>
The gadget style is independant from template
res define all the icon app and screensplash for android and ios.
To update them, you can modify the /web/pockeit/templates/main-header/config.xml (cf https://build.phonegap.com/docs/config-xml) or just update existing pictures (keep the exact same dimensions).
All the style folder will be copy in your mobile app.
The main.css is your entry point. You can import more css files using
@import url("style.css");
You can add image in the style subfolder of your choice and use them in your CSS like thant
background-image:url(img/logo.png);
