The radio button renders in every supported browser.
The radio button itself renders as the standard browser control. Style Editor changes can be made to the corresponding label.
There is no editability for radio button groups in the style editor.
If radio buttons are used with a label to the left, they have to be used in combination with the label control which points to the assigned radio button. This ensures, that screen readers are aware of the relationship between the both elements and can read the correct label to the according radio button.
