Hi, I want to make an animation with two lines. Basically the two lines should increase their width and form an "X". My problem is the rotation AND the fact that the animation should NOT start in the center of each line but on the "top-left" and "top-right" of the corresponding lines. When I rotate the lines and then perform the width animation strange things happen. I tried to get things work correct by using the "transform-origin" and "transform: translate()" properties but without success. I've attached an GIF with the X animation I want to achieve. Maybe someone can enlighten me since I'm at the very beginning of my animation career ?
