当 h1 的字体大小发生变化时，将 :hover 属性调整为新的属性

Question

我有一个小问题...当我使用@keyframes 更改了文本的外观时，我不知道如何调整 :hover 字母间距属性...更具体地说：悬停会像这样改变我的 h1 外观：字体大小、位置、字母间距等。字母间距默认为 0rem，但是当我将鼠标悬停在文本上时，它会变为 1rem。效果很好，但我添加了一个动画，它改变了位置，h1 的字体大小，from font-size: 12.5rem;字体大小：5rem；问题是当我悬停时我不知道如何更改字母间距。 font-size为12.5rem时；它看起来不错，但是当动画完成时，字体大小为 5rem，当我将鼠标悬停在它上面时，它看起来很糟糕，字母间距为 1rem。我需要一些帮助...如您所见，它会更改其位置和字体大小，悬停保持为 1 rem，当它具有 font-size12.5rem 时，我想将悬停字母间距从 1rem 更改为0.2rem idk 当我将鼠标悬停在它上面时它的字体大小为 5rem ...我希望你明白我在说什么，顺便说一句，如果我犯了任何语法错误，请随时纠正我，我不是本地人演讲者，有时我在英语方面遇到困难，因此我需要知道我什么时候错了。顺便说一句。

我建议你不要使用 <h1> 标签，因为它在不同的浏览器中有默认的 CSS 值。尽量换成普通的<div>，明确自己想要的样式
