Question

I am new to BootStrap so learning the ropes and understanding it. I am trying to acheive 100% height in column grid so that it covers 100% height of the page. Right now no heigh

Answer 1

try this:

html,body
{
  height: 100%;
}

If that doesn't work, then use inspect element, and verify that parent elements have 100% height. (Because if they don't - then child elements won't get 100% height unless they are position:absolute or position:fixed
