I had set "margin:0.6em" what lead to arkward behaviour between para-

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.
