Missing bottom margin

[Gandalf]

I have the following page htt ps://gand alf458.co.u k/map1.html

All works fine except the bottom margin isn’t showing. I notice that the body and the container div do not extend to the full length of the page, but I don’t know why. It reminds me of the clearfix probs of olden days.

Try deleting:

html, body {
  height: 100%;
}

Great, thanks!
