Using calc() in IE11 transforms by stacking
Say you wanna do this:
transform: translateY(calc(100% - 50px));
This would be great, but in IE11 you're outta luck, no calc support in transform yet.
But, you can do this:
transform: translateY(100%) translateY(-50px);
Whaaaaat? Yes, you can actually stack transformations and thereby do the same thing. Hooray.
