Elements on edges

How to use it

Take an element that usually sits inside another element, and move it so that it sits somewhere on the edge.

When to use it

You might have an action that affects the contents inside a container (e.g. expands the container), which would work well hanging from the edge (like a pull tab).

You can also do this for visual interest. e.g. a button icon normally sits inside the edges, but if you have it overlap the edges the button will stand out.

What to watch out for

If the main element casts a shadow, the element overhanging the edge might also need to cast a shadow.

Since this changes the shape of the group overall, it can make layout harder.
