How to combine different units in CSS
Nope, not anymore, thought so too. Its finally here and ready. For any modern browser you can now safely do things like:
top: calc(50% - 25px);
right: calc(25% + 50px);
bottom: calc(50% + 25px);
left: calc(25% - 50px);
Works with the other units too. Hooray.
Praise the lord!
