WCAG 2.1 H32: Providing submit buttons (wcag/h32)

WCAG 2.1 technique H32 requires each <form> element to include at least one submit button in order to allow users to interact with the form in a predictable way. For instance pressing enter in an input field to submit.

This rule checks for the presence of:

• <button type="submit">
• <input type="submit">
• <input type="image">

Submit buttons can either be nested or associated using the form attribute.
