6 // Styling checkboxes in a way that works cross browser is a tricky problem to solve.
7 // In MediaWiki UI put a checkbox and label inside a mw-ui-checkbox div.
8 // This renders in all browsers except IE6-8 which do not support the :checked selector;
9 // these are kept backwards-compatible using the :not(#noop) selector.
10 // You should give the checkbox and label matching "id" and "for" attributes, respectively.
13 // <div class="mw-ui-checkbox">
14 // <input type="checkbox" id="kss-example-5"><label for="kss-example-5">Standard checkbox</label>
16 // <div class="mw-ui-checkbox">
17 // <input type="checkbox" id="kss-example-5-checked" checked><label for="kss-example-5-checked">Standard checked checkbox</label>
19 // <div class="mw-ui-checkbox">
20 // <input type="checkbox" id="kss-example-5-disabled" disabled><label for="kss-example-5-disabled">Disabled checkbox</label>
22 // <div class="mw-ui-checkbox">
23 // <input type="checkbox" id="kss-example-5-disabled-checked" disabled checked><label for="kss-example-5-disabled-checked">Disabled checked checkbox</label>
