Label Tags

A very easily forgotten tag that makes a website more usable. The tag makes for more intuitive clicking for regular users and for those users leveraging screen readers it makes it much easier. Here's an example:

0-25yrs
26-45yrs
45+yrs

Notice how you can change your selection by clicking the text describing the option? Here is the same example without labels:

0-25yrs
26-45yrs
45+yrs
