Cognitive issue

Buttons do not have an accessible name

1. Failing elements
<button type=”submit” class=”wpr_submit”>
2. in plain words
When a button does not have an accessible name, screen readers and other assistive technologies announce it as “button”, which provides no information to users about what the button does.

#
3. WHOM DOES THIS AFFECT?
People who use screen readers, including the blind and visually impaired

#
4. HOW TO SOLVE IT:
Option 1 – Do it yourself:
For buttons with visible labels, add text content to the button element. Make the label a clear call to action. For example: <button>Book room</button>

For buttons without visible labels, like icon buttons, use the aria-label attribute to clearly describe the action to anyone using an assistive technology.
