CSS Transitions and transforms on SVG elements

Question

I am currently trying to rotate an SVG group using a CSS transform and animate it using CSS transitions. I am getting the desired transform but not the animate, any idea on

Answer 1

Fixed it!

The transition was in the wrong place, I had assumed that the transition would descend down to the children elements but apparently not. Also fixed the rotation by animating between 0 and 180 degrees.

Inline SVG
