I'm trying to do this layout:

The point is that the controls are vertically fixed in height, but some on the left have an arbitrary height control associated with them. I do this: first, there is a panel with display: block elements (vertical), inside I put a horizontal one into which I place a block with a fixed height and an arbitrary one. I tried to set the vertical-align: middle , but then this "line" becomes high and the distance between the main controls increases. How to avoid it?
