Making checkbox and radio labels clickable

Question

A large number of (dare I say most?) sites do not make the labels clickable for their checkbox and radio inputs. It seems to be a huge usability gain for very little effort.

Answer 1

No, there are no issues with that, but unfortunately this is one of the most ignored html tags. Agreed, this tag is extremely important for accessibility reasons and what is more when it comes to layouts for small devices such as mobiles, you can't live without this.
