Psuedo-class to keep div visible on focus / active?
===

I have a div that is hidden until the user clicks on a link. Using the `a:active + div` selector the div is shown. I then have `div:active, div:focus` to keep the div visible.

Whilst making the div appear was simple enough, keeping it visible is the problem I have. If I click on the div (taking the active off the link and placing focus / active on the div) then the div disappears again.

I have tried using `div:hover` and while that shows the div (even after I click on it) when I hover off the div still disappears. Why are `:active` and `:focus` not being applied to my div?
