当 h1 的 font-size 发生变化时，将 :hover 属性调整为新属性

Question

我有一个小问题...当我使用 @keyframes 更改文本的外观时，我不知道如何调整 :hover letter-spacing 属性...更具体：hover 改变了我的h1 的外观如下：字体大小、位置、字母间距等。字母间距默认为 0rem，但当我将鼠标悬停在文本上时，它变为 1rem。效果很好，但是我添加了一个动画，它改变了 h1 的位置，字体大小，从 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。当它的 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，当我将鼠标悬停在具有 1rem 字母间距的动画上时，它看起来很糟糕。我需要一些帮助...请，因为您可以看到它的位置和字体大小发生了变化，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，有时我的英语很困难，因此我需要知道我什么时候错了。谢谢顺便说一句。

我建议你不要使用<h1> 标签，因为它具有不同浏览器的默认 CSS 值。尝试将它们替换为普通的<div>，并明确您想要的样式。
