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.

15 // <label for="kss-example-3">Standard checkbox</label>

18 // <input type="checkbox" id="kss-example-3-checked" checked>
