Accessibility

The best accessibility is semantic HTML. Most screen readers understand how to parse inputs if they’re correctly formatted. When it comes to checkboxes, there are a few things to keep in mind:

  • All inputs should have an id attribute.
  • Be sure to associate the checkbox label by using the for attribute. The value here is the input’s id.
  • If you have a group of related checkboxes, use the fieldset and legend to group them together.

For more information, please read Gov.UK’s article, "Using the fieldset and legend elements".
