6 // Styling radios in a way that works cross browser is a tricky problem to solve.
7 // In MediaWiki UI put a radio and label inside a mw-ui-radio div.
8 // This renders in all browsers except IE 6-8 which do not support the :checked selector;
9 // these are kept backwards-compatible using the `:not( #noop )` selector.
10 // You should give the radio and label matching "id" and "for" attributes, respectively.
13 // <div class="mw-ui-radio">
14 // <input type="radio" id="kss-example-4" name="kss-example-4">
15 // <label for="kss-example-4">Standard radio</label>
17 // <div class="mw-ui-radio">
18 // <input type="radio" id="kss-example-4-checked" name="kss-example-4" checked>
19 // <label for="kss-example-4-checked">Standard checked radio</label>
21 // <div class="mw-ui-radio">
22 // <input type="radio" id="kss-example-4-disabled" name="kss-example-4-disabled" disabled>
