Vertically center a div.

[Theriex]

I know this has been asked again and again but after much searching on Google and numerous attempts myself, I am unable to come up with a solution that works.

I am trying to center a DIV vertically inside of another DIV. The outer DIV has a height that is set using document.documentElement.clientHieght. The inner DIV's height is variable and unknown.

Any help is appreciated. Thanks

Have a look at this dead centre.

Thanks, I managed to rewrite it from the ground up quickly enough and resolved the issue.
