I boiled this down to as few code as I could without loosing function. You have to run this in Firefox, Chrome has an already reported and confirmed bug involved.

I have a question regarding :focus. I want to have a button/text that shows <div class="contentbox2"> when clicked, but i’m really struggling with that. I tried several ways but i can only make the contentbox show up when clicked and not “connect” it with the button.
