17 * Viewport height fix for mobile browsers.
18 *
19 * Mobile browsers subtract the address bar from 100vh inconsistently.
20 * We set --vh and --vvh on :root so CSS can use calc(var(--vh) * 100)
21 * instead of 100vh.
22 *
23 *   --vh  : 1/100 of window.innerHeight  (layout viewport)
24 *   --vvh : 1/100 of visualViewport.height (visible area, shrinks when keyboard opens)
25 *   --vvot: visualViewport.offsetTop (non-zero when page is zoomed/scrolled)
