Answer 1

您应该使用border-top来代替overline,一些padding-top垫了绳子和顶部划线之间的间距.

请注意,使用border-top: 4px solid transparent;它只是transparent border为了保留空间,因为如果您不使用它,您的菜单项将会动摇,:hover因为CSS默认框模型计算border元素外部而不是内部,这将导致元素轻推. .

演示

HTML

<ul>
    <li><a href="#">Hello</a></li>
    <li><a href="#">World</a></li>
</ul>

CSS

ul {
    margin: 40px;
}

ul li {
    display: inline-block;
    padding-top: 5px;
    margin-right: 10px;
    border-top: 4px solid transparent;
}

ul li:hover {
    border-top: 4px solid #f00;
}

控制width使用:before或:after伪,HTML保持如上..

    content: "";
    top: 0;
