我有两个问题,第一个是2 CHAINZ
在其父ul
中的位置。我希望它在ul
元素的中间。我尝试使用margin: 0 auto;
和text-align: center;
,但他们不工作,总是留在左边。
第二个是我试图将facebook图标向右移动,我将float: right;
放在那里,但它仍然无法正常工作。你能救我吗?谢谢!
另外,我试图将它放在jsfiddle http://jsfiddle.net/raua0Lku/中,但它无法显示导航栏。但它适用于我的笔记本电脑镀铬。这是为什么......
更新:
我只是做了一些改动,让2 CHAINZ
在中间,但我仍然没有弄清楚如何在右边制作facebook图标..
答案 0 :(得分:1)
试试吧;
<ul class = "navbar-nav navbarmiddle" style="margin: 0 auto; text-align: center;">
2 CHAINZ
</ul>
<ul class = "navbar-nav navbarright" style="float: right;">
<a href=# class="fa fa-facebook"></a>
</ul>
最后,如果你更改css文件,你的网站刷新ctrl + f5。可能存在与缓存相关的问题。

这里是一个干净的解决方案,不需要任何CSS攻击,只能使用本机Bootstrap 4类(单击&#34;运行代码片段&#34;按钮并展开到完整窗口进行检查) :

注意第一个2 CHAINZ
元素如何具有类d-block d-lg-none
,使其出现在较小的屏幕上,但在大(lg)屏幕上消失。
位于中间的另一个2 CHAINZ
元素仅出现在大(lg)屏幕上,但在较小的屏幕上消失。
图标上的ml-auto
类(margin-left:auto)将2 CHAINZ
元素推向中间,始终保持居中。
