在另一个flex内部对齐flex

Question

我正在尝试创建一个移动布局，其中间的左侧导航栏中带有徽标，而人字形文字可以显示和隐藏导航栏的各项（我现在不打算执行此功能）。

但是现在我正在尝试实现以下目标：

+------+---------+---------+
| logo |  lorem  | chevron |
+------+---------+---------+
       | ipsum   |         
       +---------+
       | dolorem |    
       +---------+

我一直在尝试将ul的第一项与图标对齐。

关于在保持html语法的同时如何实现这一目标的任何想法？

Answer 1

在您的.main-nav__list中，添加：

/* Add margin: 0; and height: 300%; */
margin: 0;
height: 300%;

致您的.main-nav__list-item。添加：

/* Add flex-grow: 1; and center items */
flex-grow: 1;
display: flex;
align-items: center;
justify-content: center;
