html - 导航栏项目在悬停时变大？

Question

我对一些按钮进行了一些更改，现在我的导航栏项目在悬停时变得更大，这是一种不希望的行为。

将鼠标悬停在导航栏中的徽标上时，此行为更加明显。

Answer 1

这是因为footer.css第 38 行：

li.footer_nav_links a:focus, a:hover {
    font-size: 12px;
    color: rgb(2, 214, 158);
    text-decoration: none;
}

摆脱font-size: 12px那里，它会没事的。也许，您a:hover以通用方式使用，因此<a>在悬停时会影响所有标签。你的意思是li.footer_nav_links a:hover？

li.footer_nav_links a:focus, li.footer_nav_links a:hover {
    font-size: 12px;
    color: rgb(2, 214, 158);
    text-decoration: none;
}
