how to make column height 100% like ? I have background images I cover a .col div but I was originally adding a height:100vh; to the class which contained the background image. However when I deploy to android then the CSS property is not being registered. This must mean 100vh is not supported in that version. Anyways, is there anyway to set column height to 100%- i also tried 100% with min-height:100% to no avail.
