Question

我一直在尝试学习bootstrap 4，但是我在导航栏上挣扎。我在适当的时间出现了该图标，然后显然做了一些使它弄乱的事情，现在我什至无法显示该图标，而且我也无法使链接下降。

          <button class="navbar-toggler" type="button" data-toggle="collapse"   data-target="#navbarResponsive">

Answer 1

尝试在nav标签上添加“ navbar-light”和“ bg-light”类。缺少背景色。

然后从div ID中删除“＃”。将id =“＃navbarResponsive”更改为id =“ navbarResponsive”

祝你好运
