Frosty Jack : CSS Animated UI

Frosty jack

Made an interactive user interface element in CSS. Idea is that the elements take as less space as possible and reveals the labels only on hover, so that the user can be sure that s/he is not guessing the functionality from the icons.
Check it out at the Prabrothers' laboratory.

Total amateur in CSS transitions at work. Please let me know if there's any way I can improve my code/design.

Built for Drops app.
