If you have multiple buttons that should sit side-by-side on the same line instead of stacked like the default buttons, wrap the buttons in a container that has a data-inline="true" attribute. This will style the buttons to be the width of their content and float the buttons so they sit on the same line.
<div data-inline="true">
<a href="index.html" data-role="button">Cancel</a>
<a href="index.html" data-role="button">Save</a>
</div>

Cancel SaveIf you want buttons to sit side-by-side but stretch to fill the width of the screen, you can use the content column grids to put normal full-width buttons into 2- or 3-columns.
