Text subpixel rendering
Chrome will by default always render text to align it with the closest pixel.
That means that a text with margin-top: 10px and margin-top: 10.4px will be rendered identically.
This leads to an oscillation effect can make your animations less smooth and more jarring.
To counter this effect, you can render your text with:
- A
transformproperty - An additional
perspective()transform - A
willChange: "transform"CSS property
Notice the difference in this 200x100 video:
Left side of the video<div style={{ transform: 'translateY(' + interpolate(frame, [0, 200], [0, 50]) + 'px)', }} > hi there </div>
Right side of the video<div style={{ transform: 'perspective(100px) translateY(' + interpolate(frame, [0, 200], [0, 50]) + 'px)', willChange: 'transform', }} > hi there </div>
Consider using this optimization only during rendering as excessive will-change: transform will use more resources.
