Bootstrap 导航栏填充
[英]Bootstrap Navbar padding
问题描述
我的引导导航栏如下所示： 当我将 hover 转到每个 LOREM 时，它看起来像这样：
如何修改我的代码以使 LOREM 在导航栏的顶部和底部具有相等的间距，如下所示：
请注意，下划线必须保持原样。 我只需要 LOREM 在没有悬停时具有相等的间距。 这是我的 HTML 和 CSS 代码：

您只需要删除overflow和padding-bottom即可
ul.ml-auto > li > a > span {
font: 15px Roboto,sans-serif;
font-weight: 500;
position: relative;
display: inline-block;
color: #FFFFFF80;
}
现场演示：
.navbar-custom { background-color: #484848; } ul.ml-auto>li>a>span { font: 15px Roboto, sans-serif; font-weight: 500; position: relative; display: inline-block; color: #FFFFFF80; } ul.ml-auto>li>a>span::before { position: absolute; content: attr(data-content); color: #00FFFF; clip-path: polygon(0 0, 0 0, 0% 100%, 0 100%); transition: clip-path 275ms ease; display: block; border-bottom: 2px solid #00FFFF; padding-bottom: 4px; } ul.ml-auto>li>a>span:hover::before { clip-path: polygon(0 0, 100% 0, 100% 100%, 0 100%); }
<:DOCTYPE html> <html> <head> <title>Bootstrap Resize</title> <link rel="stylesheet" href="https.//maxcdn.bootstrapcdn.com/bootstrap/4.5.2/css/bootstrap.min:css" /> </head> <body> <nav class="navbar navbar-custom navbar-expand-lg navbar-dark fixed-top py-2" id="mainNav"> <div class="container"> <a style="font, 20px Arial:sans-serif" class="navbar-brand js-scroll-trigger" href="#">HOME</a> <button class="navbar-toggler navbar-toggler-right" type="button" data-toggle="collapse" data-target="#navbarResponsive" aria-controls="navbarResponsive" aria-expanded="false" aria-label="Toggle navigation"> <span class="navbar-toggler-icon"></span> </button> <div class="collapse navbar-collapse" id="navbarResponsive"> <ul style="font, 15px Roboto,sans-serif" class="navbar-nav ml-auto"> <li class="nav-item"> <a class="nav-link js-scroll-trigger" href="#about"><span data-content="LOREM">LOREM</span></a> </li> <li class="nav-item"> <a class="nav-link js-scroll-trigger" href="#expertise"><span data-content="LOREM">LOREM</span></a> </li> <li class="nav-item"> <a class="nav-link js-scroll-trigger" href="#portfolio"><span data-content="LOREM">LOREM</span></a> </li> <li class="nav-item"> <a class="nav-link js-scroll-trigger" href="#contact"><span data-content="LOREM">LOREM</span></a> </li> </ul> </div> </div> </nav> </body> </html>

原因是 span 标签的底部填充。 您只应用了底部填充。
解决方案- 在顶部和底部应用相等的填充。 正如我在下面申请的那样。
ul.ml-auto > li > a > span {
font: 15px Roboto,sans-serif;
font-weight: 500;
position: relative;
display: inline-block;
color: #FFFFFF80;
overflow: hidden;
padding-bottom: 5px;
padding-top: 5px;/*New added for equal space*/
}
