Checkpoints - Do not use "onmousedown" without "onkeydown"
Why is this important?
The onmousedown behavior is used to provide a style change on an element upon clicking on mouse button. We need to consider that there are users who cannot use a mouse and are using a keyboard instead. In this instance the website should have a corresponding style change onkeydown to provide a similar experience for keyboard users.
How can I resolve this issue?
Add onkeydown when you use onmousedwon
What topics do this checkpoint affect?
Accessibility (WCAG 2 Level A, 2.1.1)
Can you explain how this checkpoint works?
This checkpoint examines the entire HTML source code and reports if the onmousedown event is used without an onkeydown event
