Actual Result
The radio buttons such as "I have forgotten user name" and "I have forgotten password" are not programmatically grouped and associated with "What is preventing you from logging in?" instruction. As a result it will create bad user experience for screen reader users. Moreover incomplete information is conveyed for them.
Expected result
The screen reader should announce the instruction along with the label for the radio buttons. in this instance, Include the instruction "What is preventing you from logging in?" within <legend> element. Use <fieldset>and <legend> elements to group the instruction and radio buttons.
