/**
|
|
* Redefinition of the mw-ui-icon class from MediaWiki-core.
|
|
*
|
|
* This module attempts to maintain compatibility with the
|
|
* core mw-ui-icon module, while adding more mobile-friendly
|
|
* features like increased touch-area sizes and highlights.
|
|
*
|
|
* - mw-ui-icon = base class. 20px square with icon.
|
|
* - mw-ui-icon + mw-ui-icon-element = icon with padding & pseudo-states.
|
|
* - mw-ui-icon + mw-ui-icon-small = small icon with padding & pseudo-states.
|
|
* - mw-ui-icon + mw-ui-icon-flush-left = negative right-margin.
|
|
* - mw-ui-icon + mw-ui-icon-flush-right = negative left-margin.
|
|
* - mw-ui-icon + mw-ui-icon-before = *deprecated*, icon with text.
|
|
* Labels should be placed in a separate element beside the icon.
|
|
*
