通常，我会做 position: relative 和 left: 500px。但是，Bootstrap 最好的部分是它的响应性。我不想摆脱 Bootstrap 的响应式特性。如何在我的导航栏中将 Bootstrap 中的 li 居中？
请在整页模式下查看片段。我的目标是将两个“链接”移动到 div 的中间。他们都是李氏。我该如何实现？

就这样吧——
添加一个类 .navbar-centre 到包含要居中的链接的 ul。
然后像片段一样添加 css。
@media (min-width: 768px) {
.navbar-nav.navbar-center {
position: absolute;
left: 50%;
transform: translatex(-50%);
}
