Calculator - CalcSS3

This is a CSS3 remake of the well known iPhone™ calculator. (No images, only CSS).
This scientific calculator works just like most other calculators of its kind and probably doesn't need any further explanations ;o).
Find some more info/help by clicking the '?' in the left top corner of the calculator's screen or see: Using the Calculator.

CalcSS3 used to be an exercise to learn 'new' features of CSS3 in 2010, but I could not resist making it work... so I did. It is not a best practice example, it is more like a review from back then, but it works quite good. Have fun!
Find CalcSS3 as a Chrome extension at the Google App Store
