I have a site with an element that is 100vh:
height:100%; /* for older browsers */
height:100vh;
This works fine on the desktop browsers I tested it in, as well as in Chrome on Android.
But both in Firefox on Android and the default Android web browser, the element is somewhat taller than the browser tab, maybe (eyeballed) as tall as the window plus the tab header.
Why is that so, and how do I avoid it?
