A safer way to vertically fill the viewport

Using min-height: 100vh works great for filling the viewport, but a safer way is to progressively use -webkit-fill-available to account for a long-standing iOS issue with 100vh.

html {
  height: -webkit-fill-available;
}

body {
  min-height: 100vh;
  min-height: -webkit-fill-available;
}

This is by no means a perfect fix, but it’s a little more acceptable if you need docked elements on your page.
