4 // Checkbox
5 //
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.
12 // Markup:
13 // <div class="mw-ui-checkbox">
14 //   <input type="checkbox" id="kss-example-3">
15 //   <label for="kss-example-3">Standard checkbox</label>
16 // </div>
17 // <div class="mw-ui-checkbox">
18 //   <input type="checkbox" id="kss-example-3-checked" checked>
19 //   <label for="kss-example-3-checked">Standard checked checkbox</label>
20 // </div>
21 // <div class="mw-ui-checkbox">
22 //   <input type="checkbox" id="kss-example-3-disabled" disabled>
23 //   <label for="kss-example-3-disabled">Disabled checkbox</label>
24 // </div>
25 // <div class="mw-ui-checkbox">
26 //   <input type="checkbox" id="kss-example-3-disabled-checked" disabled checked>
27 //   <label for="kss-example-3-disabled-checked">Disabled checked checkbox</label>
