隐藏导航栏中的图标并仅在悬停时显示文本

时间：2018-02-14 19:11:38

标签： html css

我正在使用带有图标的导航侧边栏，这些图标在悬停时显示文字以及参考JFarrow https://codepen.io/JFarrow/pen/fFrpg

的图标 
ESP

但在我的情况下，当我将鼠标悬停在侧边栏上并仅显示文字时，我想隐藏图标。

我知道最佳方法吗？

您需要将IPageFilter和width:0设置为visibility:hidden上的fa

同样使用.main-menu:hover ...不要在flexbox元素上使用表格。

默认显示无图标，然后添加hover css属性。像这样的东西，

           <li>
                  <a href="http://justinfarrow.com">
                    <i class="fa fa-home fa-2x my_icon"></i>
                    <span class="nav-text">
                        Dashboard
                    </span>
                </a>

            </li>

           <style>
             .my_icon{
                         display :none;
                  }

            .my_icon:hover{
                         display :visible;
                  }
           </style>
