Question

我正在为我的高中机器人团队制作一个网站，我不熟悉HTML和CSS（bootstrap）。我不希望我的横幅和我的网站中的导航栏之间有空格。如何消除这个空间？

Answer 1

只需将元素的margin-bottom设置为零：

#top-jumbotron { margin-bottom: 0; }

此处示例：http://www.bootply.com/xQvinJhNLN

Answer 2

您可以使用上面显示的CSS。或者，您可以使用Bootstrap随附的类：

<jumbotron class="mb-0">
     <!-- Anything you are putting in the jumbotron -->
</jumbotron>

这些类可以与各种Bootstrap组件一起使用。这是链接：https://getbootstrap.com/docs/4.0/utilities/spacing/

如何在bootstrap中摆脱我的jumbotron底部边缘？
