Bootstrap 4.5.3导航栏切换不起作用 [英] Bootstrap 4.5.3 navbar toggle is not working
问题描述
我正在使用由HTML CSS和Bootstrap制成的导航栏.我已经看过youtube上的一些教程，但是当屏幕尺寸减小到最小时，我似乎可以展开切换按钮.由于我开始一个新项目，所以我将所有这些都应用了HTML CSS和Bootstrap，并在本地目录中打开了HTML文件.
I am working on a navbar that was made out of HTML CSS and Bootstrap. I had followed some tutorials on youtube but I can seem to expand the toggle button when the screen size is reduced to the smallest. Since I'm starting a new project, I applied all of this with HTML CSS, and Bootstrap and opened the HTML file in my local directory.

推荐答案
我创建了 codeply 对您来说，您的代码没有错误，您只需要在代码中添加一些< script> .我建议您使用 cdn .
I created a codeply for you, there is no error in your code, you just need to add a few <script>s into your code. I recommend you to use the cdn.
