But actions are more than deploy and publish. That’s what’s so cool about them. They’re containers all the way down, so you could quite literally do pretty much anything — the possibilities are endless!

How to create very cool effects with a rarely used feature: When you use eight values specifying border-radius in CSS, you can create organic looking shapes.

Using negative grid lines allows us to place items relative to the end of the grid. This is especially useful if we have a large grid – it means we don’t have to work out the exact line number from the start, we could simply place it from the end.
