# will-change is applied too broadly

`smooth/will-change-overuse` · severity **info** · category Smoothness · detected by `void smooth` and `void audit`

## Why it matters

Every will-change layer costs GPU memory; applying it statically to many elements (or html/body) can make scrolling worse, not better.

## How to fix it

Set will-change only on the few elements about to animate, ideally just before the interaction, and remove it afterwards.

## More smoothness rules

`void smooth` reports 13 rules in this category. How the page feels after it loads: dropped frames during a scripted scroll, long animation frames, INP of real clicks, shifts after input, animated layout properties, idle rAF loops and reduced-motion handling.
