A fun example of how Profound UI widgets can be totally customized.

This calculator is based off of the stateless rich display file template, and illustrates several interesting things that can be done with Profound.js Spaces:

Setting widget properties in the Designer
Setting other widget properties in a CSS file
Using CSS transition animations with Profound.js Spaces widgets
Making key presses perform the same actions as mouse clicks

The way it works is each button (a styled label, actually) employs onmousedown and onmouseup events to call functions in the main JavaScript code. As numbers are typed, they are concatenated together until an operator button (+, -, etc.) is pressed, whereupon the concatenated number is stored and later used after a second number and operator are entered.

CSS transition animations are used to visually indicate which buttons are being pressed.

Possible iOS Safari Bug

Simple space to demonstrate what appears to be a rendering bug in mobile Safari. Run this space on an iPhone running 12.2 or higher, rotate the phone to landscape, then rotate back to portrait. If the issue occurs, there will be an unusable white space at the bottom of the screen.
