jQuery Mobile provides two different style themes, “a” and “b” – each with different colors for buttons, bars, content blocks, and so on.
<div data-role="page" data-theme="a|b">
For buttons with class=”ui-btn”, use the “ui-btn-a|b” class to style the button either gray (default) or black:
<a href="#" class="ui-btn ui-btn-a|b">Button</a>
