How to remove animation in mobile browsers?

Question

Mobile development

When I click on a link or button on a mobile browser, I see the default animation. On Android, a transparent blue background appears. On iOS, a transparent black background. How to remove it?

Answer 1

This is not an animation, but a tapa highlight.
Turned off like this:
-webkit-tap-highlight-color: rgba(0, 0, 0, 0);
