Question

当链接悬停时，我正在尝试使用下划线。但是，您会注意到下划线不会与下面的线齐平。有人可以解释或告诉我如何更改此CSS工作，所以当链接悬停时，3px行位于跨越页面的1px行的顶部。谢谢

<!DOCTYPE html>
<html>
<head>
<style>
.menu {
    font-family: "Helvetica Neue", verdana, arial; 
    position:fixed; 
    background:transparent;
    width:100%; 
    top:100px; 
    left:0; 
    height:25px;       /* decide on this as some stage */
    padding: 0;
    text-align:center;
    font-size: 12px;
    font-weight: 600;  /* decide on this as some stage */
    padding-top: 10px;  /* decide on this as some stage */
    border-bottom: 1px solid #ccc;
    border-top: 1px solid #ccc;
}

.ty-menu__items {
    position: absolute;
    list-style-type: none;
    margin: 0;
    padding: 0;
    overflow: hidden;
    width:100%;
    text-align: center;
}

.ty-menu__item {
    display: inline-block;
    padding-right: 50px;
    padding-left: 50px;
    }

a:link, a:visited {
    display: block;
    width: 100%;
    font-weight: light;
    color: #494949;
    background: transparent;
    text-align: center;
    text-decoration: none;
    text-transform: uppercase;
}

a:hover, a:active {
    background: transparent;
    border-bottom: 3px solid #494949; /* decide on this as some stage */
    color: #494949; /* decide on this as some stage */
}

Answer 1

我在你的悬停中添加了一个填充底部，看起来像3px一样位于1px的顶部。

a:hover, a:active {
    padding-bottom:8px;
    background: transparent;
    border-bottom: 3px solid #494949; /* decide on this as some stage */
    color: #494949; /* decide on this as some stage */
}

如果我认为我理解

，我就把它改成了

.menu {
    font-family: "Helvetica Neue", verdana, arial; 
    position:fixed; 
    background:transparent;
    width:100%; 
    top:100px; 
    left:0; 
    height:35px;       /* decide on this as some stage */
    padding: 0;
    text-align:center;
    font-size: 12px;
    font-weight: 600;  /* decide on this as some stage */
    padding-top: 10px;  /* decide on this as some stage */
    border-bottom: 1px solid #ccc;
    border-top: 1px solid #ccc;
}

.ty-menu__items {
    position: absolute;
    list-style-type: none;
    margin: 0;
    padding: 0;
    overflow: hidden;
    width:100%;
    text-align: center;
}

.ty-menu__item {
    display: inline-block;
    padding-right: 50px;
    padding-left: 50px;
    }

a:link, a:visited {
    display: block;
    width: 100%;
    font-weight: light;
    color: #494949;
    background: transparent;
    text-align: center;
    text-decoration: none;
    text-transform: uppercase;
}

a:hover, a:active {
    padding-bottom:1px;
    background: transparent;
    border-bottom: 3px solid #494949; /* decide on this as some stage */
    color: #494949; /* decide on this as some stage */
}

即我更改了.menu：height
