On a mobile device the accordion heading covers the width of the page but the accordion body (when it is opened) covers only approximately 2/3 of the page width.
1. The problem exists in Chrome and Firefox but not in Android's stock browser.
2. The problem exists in portrait view and not in landscape.
Any idea what causes this and how it could be sorted out?
P.S. I am using the Visual theme which is a responsive theme.
