Dropdown menu without javascript - html

Question

I have a menu with tabs, and on hover of a tab a list of things appear at the bottom of the tab. Then, I wanted to do that the list of thing go down with a transition( before it was display:block). My problem is that when the transition will start, the top of the list must be a certain multiplication ( the width of a tab * the number of tabs ). But I don't want any javascript.
Is there a way to do that ?
