我希望导航栏的底部分隔符与页面的其余部分对齐。就像重构UI一样here
但是,当我在导航栏内的容器中添加边框时,边框会扩展到so之类的内容之外。
<nav class="navbar navbar-expand-lg">
<div class="container" style="border-bottom: 3px solid blue;">
<a class="navbar-brand" href="/index...
我可以在navbar-element外部添加一个容器,并在其中添加一个<hr>
元素,但这似乎是一种不好的做法。
向导航栏添加水平分隔符以与页面其余部分的内容对齐的一种优雅且“正确”的方法是什么?

如果您添加一个row
元素并为其添加样式,而不是向您的container
添加样式,则可以解决您的问题。
示例:
<nav class="navbar navbar-expand-lg">
<div class="container">
<div class="row" style="border-bottom: 3px solid blue;">
<a class="navbar-brand" href="/index...
row
的左侧和右侧将填充15px
。由于div已嵌套,因此应该减小border-bottom
的宽度。
选项二(不更改其下方元素的布局):
<div class="container">
<div class="row" style="border-bottom: 3px solid blue;"></div>
<a class="navbar-brand" href="/index...
或者您可以使用自定义样式<hr>
,但该选项没有任何问题。

您应该在nav标签而不是其他分区处进行操作,因为这样做可以同时更改所有内容和导航的页边距,并以相同的方式对齐。
