|
|
// Notes:
|
|
//
|
|
// - Usage requires three elements: a hidden checkbox input, a button, and a show / hide target.
|
|
// - By convention, the checked state is considered expanded or visible. Unchecked is considered
|
|
// hidden.
|
|
// - Please see additional documentation in checkboxHack.js for example HTML and JavaScript
|
|
// integration.
|
|
//
|
|
// Example supplemental styles (to be added on a per use case basis):
|
|
//
|
|
// - Animate target in and out from start (left in LTR) to end (right in LTR):
|
|
//
|
|
// .mw-checkbox-hack-checkbox:not( :checked ) ~ .mw-checkbox-hack-target {
|
|
// // Turn off presentation so that screen readers get the same effect as visually
|
|
// // hiding. Visibility and opacity can be animated. If animation is unnecessary, all
|
|
// // of this can be replaced with `display: none` instead to avoid hidden rendering.
|
|
// visibility: hidden;
|
|
// opacity: 0;
|
|
// @timing: @transition-duration-base ease-in-out;
|
|
// .transition( transform @timing, opacity @timing, visibility @timing; );
|
|
// .transform( translateX( -100% ) );
|
|
// }
|
|
//
|
|
// - Show / hide the target instantly without animation:
|
|
//
|
|
// .mw-checkbox-hack-checkbox:not( :checked ) ~ .mw-checkbox-hack-target {
|
|
// display: none;
|
|
// }
|

.mw-checkbox-hack-checkbox {
|

|
|
// Always lower the checkbox behind the foreground content.
