| /** |
| * Modified code based on remPolyfill.js (c) Nicolas Bouvrette https://github.com/nbouvrette/remPolyfill |
| * |
| * Customizations: |
| * |
| * 1) Added new method `addCallBackWhenReady` to perform callbacks once the polyfill has been applied (especially useful for |
| * onload scrolling events. |
| * 2) Added REM support. |
