Page Styling

The Widget Framework provides Bootstrap-based styling for AMP pages in the form of a theme called amp. You can modify the supplied amp theme in exactly the same way as you would modify any other theme. Note, however, that AMP imposes restrictions on CSS, so any changes you make to the supplied CSS must be AMP-compliant. For general information about themes and how to work with them, see Themes.

As required by AMP the CSS is included directly in the HTML rather than in an external file.
