No 300ms tap delay

Legacy mobile browsers inserted a 300ms delay on tap events to distinguish between a single tap and a double-tap-to-zoom gesture. That delay makes buttons feel sluggish and unresponsive compared to native apps. Modern browsers eliminate the delay when a correct viewport meta tag is present, but older WebViews and some embedded browsers still apply it. touch-action: manipulation disables the double-tap-zoom gesture on interactive elements, removing the delay explicitly.

If the viewport meta check already passes, no further action is required for modern browsers. For extra coverage on older mobile WebViews, add touch-action: manipulation to buttons, links, and anything with role="button" in your global CSS.

button, a, [role="button"] { touch-action: manipulation; }
