Technique ARIA21: Using aria-invalid to Indicate An Error Field

[madisilvesagile]

In the example:

<div>
    <label for="email">Email (required)</label>
    <input type="text" name="email" id="email">
  </div>

Type should be email
See correct version:

<div>
    <label for="email">Email (required)</label>
    <input type="email" name="email" id="email">
  </div>

There's 3 markup examples all of them have the same mistake.

not a "mistake". it's perfectly valid to use type="text" even for emails in your markup (noting also that these techniques were created about a decade before type="email" even existed)
