First I did set the body bottom margin to 0. I don't know why.
Second the reset part included a margin removal too. Deleted it.
Third removed the calculated body height.
Forth I can now remove the ugly div with class .space. Didn't work too.

Just to have a clener app, move the whole help part into a closed detail
tag.

I had set "margin:0.6em" what lead to arkward behaviour between para-
graphs. It ignored one of top or bottom margin. As it is best practice
to define margins in one direction not in both I changed it to "margin-
bottom:1.2em". See that I doubled the value.

Dialog shows frequency in big letters. Prevent scrolling the body behind
the dialog. Otherwise you can find yourself on another position when
closing.
