问题描述

我有个问题。我正在使用以下代码：

@import url(//netdna.bootstrapcdn.com/font-awesome/4.0.3/css/font-awesome.css);

@import url(https://fonts.googleapis.com/css?family=Titillium+Web:300);

text-align: center;
vertical-align: middle;
font-size:20px;
}


.main-menu:hover,nav.main-menu.expanded {
width:250px;
overflow:visible;
}

.main-menu {

.main-menu li>a {

text-decoration:none;
-webkit-transform:translateZ(0) scale(1,1);

            <li class="has-subnav">
                <a href="#">
                    <i class="fas fa-undo"></i>

            </li>  
        </ul>
    </nav>

    </body>

但正如您所见，导航栏现在与内容重叠。我已经尝试设置areato的位置relative，但这并没有做任何事情。CSS 不是我最喜欢做的事情，我不知道如何在导航栏旁边设置内容。我想要的是导航栏在折叠时不会与内容重叠，但它可以折叠内容，所以当导航栏很小时，该区域中的所有内容都是可见的。

我怎样才能做到这一点？
