Fast Int Math + Bitwise Hacks For JavaScript
/**
* Bitwise Mathematics Utilities
*
* A collection of fast bitwise operations for integer mathematics.
* These functions prioritize performance over readability and should be used
* when micro-optimizations are critical (game engines, real-time applications).

Survey of screenshot-based CSS testing tools

Currently considering https://github.com/webdriverio/webdrivercss

Core Goals:

  • Can test in up-to-date versions of all major browsers
  • Can test on up-to-date versions of all major OSes
  • Can test in IE9 (because Bootstrap v4 will support IE9+)
  • Don't want to have to setup/maintain our own cluster of VMs running all the necessary OSes (and all the versions of Windows)
  • Workflow for management of reference/baseline/norm screenshots

Be aware that every rendering engine has its own implementation of prefixed properties. As extensions are made part of the standard, the unprefixed identifier is then substituted.

Prefixed style properties

-ms-accelerator

The -ms-accelerator property sets or retrieves a string that indicates whether the object represents a keyboard shortcut.

-ms-accelerator: false | true
