+# Structure
+
+To use the `RadioGroup` css in `@miljodirektoratet/md-css` as a standalone, without the accompanying React component, please use the following HTML structure.
+
+Class names in brackets [] are optional-/togglable-/decorator- or state dependant classes.
+
+See [Storybook](https://miljodir.github.io/md-components) for examples and more info.

+    <div className="md-radiobutton [md-checkbox--disabled]">

+        <span className="md-radiobutton__selected-dot" />
