Was führt dazu, dass CSS-Textanimationen beim Laden übermäßig zittern?

Ich habe jeden Trick ausprobiert, den ich finden konnte, aber die Animation ist immer noch sehr unruhig. Ich habe versucht, einige Ratschläge zu einer anderen Frage zu befolgen, bei denen die Verwendung empfohlen wurde transition 而不是 keyframes 但似乎仅使用 transition Ich muss Javascript verwenden, was ich vermeiden möchte.

Das ist der Clip:

    按照用户@JHeth的建议,我将位置值添加到@Keyframes

    transform: perspective(0px) translate3d(-50px, 15px, 0px) translateZ(0px);

    它成功了。现在动画就像丝绸一样光滑。
