Forked from Ideaviate/html5-css3-js-calculator on 9/7/2016
-
Applied 7-segment font from http://www.keshikan.net/fonts-e.html
-
Added "FLIP" button that flips the calculator upside-down so you can read any words you've created
-
Visual tweaks to round corners and button font size
-
My text editor mangled the "divided-by" symbol so I changed it to "/" within the code and specified the HTML entity designator ÷ for display.
This was a small project we did just to play around with some of the latest web tools, such as KnockoutJS. We wanted to design and build something that looked clean, used no images and with a small amount of code.
The result was a simple calculator built with pure CSS and a little bit of JavaScript and Knockout love.
The calculator also has keyboard support through your keyboard numpad.
We published a demo where you can try the calculator online. The demo is also included if you clone the repo.
