Question

所以，我在网上使用了侧边栏菜单。首先，这个侧边栏只有100px，当我将鼠标悬停在它上面时，它会显示所有侧边栏。这是悬停之前和之后的图像：

我的HTML代码：

＆＃13;

   .sidenav {
            height: 100%;
            width: 100px; 
            position: fixed;
            z-index: 2;
            top: 0;
            left: 0;
            background-color: #111;
            overflow-x: hidden; 
            padding-top: 60px; 
            transition: 0.8s;
        }
        
        .sidenav:hover{
           width: 250px;
           transition: 0.8s;
        }
    
    .sidenav a {
        float:left;
        width:100%;
        padding: 8px 8px 8px 32px;
        text-decoration: none;
        font-size: 20px;
        color: #818181;
        display: block;
        opacity: 0;
        transition: opacity 1300ms
    }
    .sidenav:hover a {
        opacity: 1
    }


    .icon{
      display: block;
        position: relative;
        left: 50%;
        top: 50%;
        width: 15px;
        height: 15px;
        float: left;
        border-radius: 50%;
        border: 1px solid red;
        border-top-color: transparent;
        -webkit-animation: spin 2s linear infinite;
        animation: spin 2s linear infinite;
    }

＆＃13;

    <body>
    <div id="mySidenav" class="sidenav"> <!-- CSSnya di 2691 -->
      <br><br>
      <a href="#">Home</a>
      <a href="#">Menu 1</a>
      <a href="#">Menu 2</a>
      <a href="#">Menu 3</a>
      <a href="#">Menu 4</a>
      <a href="#">Menu 5</a>
    </div>
    </body>

＆＃13;

当侧边栏没有悬停时，我的所有链接菜单都会隐藏，并会在悬停时显示。我的问题是如何只在侧边栏没有悬停时显示图标，并在悬停时显示所有图标，我使用此类：所以它仍然显示侧边栏没有悬停，仍然在链接菜单的一行？感谢

您可以使用FontAwesome作为图标。希望它有所帮助。

.sidenav a {
    float: left;
    width: 250px;
    padding: 8px 8px 8px 32px;
    text-decoration: none;
    font-size: 16px;
    display: block;
    line-height: 37px;
    color: transparent;
    transition: 1300ms;
    height: 30px;
    font-family: arial;
    letter-spacing: 1px;
    text-transform: uppercase;
}
i {
    display: block;
    position: relative;
    width: 15px;
    height: 15px;
    float: left;
    border-radius: 50px;
    border: 1px solid red;
    padding: 10px;
    text-align: center;
    line-height: 15px !important;
    color: #fff;
    opacity: 1;
    margin-right: 10px;
    font-size: 15px !important;
}
.sidenav {
    width: 100px;
    left: 0;
    background-color: #111;
    overflow-x: hidden;
    padding-top: 60px;
    transition: 0.8s;
}
.sidenav:hover {
    width: 250px;
    overflow: hidden;
    transition: 0.8s;
}
.sidenav:hover a {
    color: #fff;
}

<script src="https://use.fontawesome.com/7a90a673fc.js"></script>
<div id="mySidenav" class="sidenav"> 
  <br><br>
  <a href="#"><i class="fa fa-bars"></i> Home</a>
  <a href="#"><i class="fa fa-comment"></i> Menu 1</a>
  <a href="#"><i class="fa fa-users"></i> Menu 2</a>
  <a href="#"><i class="fa fa-thumbs-up"></i> Menu 3</a>
  <a href="#"><i class="fa fa-facebook"></i> Menu 4</a>
  <a href="#"><i class="fa fa-close"></i> Menu 5</a>
