Exhibit 5: Empty Buttons
Inaccessible Gallery
Explanation
An empty button means that a screen reader announces a button as such and that it's clickable, but it can't tell users what the button does when there is no text information.
In this demo, buttons have the same text color as the background color. All sighted users can see is a shape indicating that there a two buttons (one is greenish-blue and the other red).
