I’ve seen a very interesting widget in BBC News Client. It’s originally just a
common hamburger sign, but it would transition to an left arrow when the user
slide the sidebar open in clock-wise way and it also transition back to
hamburger when the sidebar is hidden.
This effect reminds me of an interesting pure CSS implementation of hamburger animation. And I’d like to implement this widget in a similar fashion.
