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