Question

我想将鼠标悬停在图标上，以便显示before元素，但是每次我将其悬停时，图标都会消失，并且当我将鼠标悬停在图标的右半部分时，什么也没发生。如果我将before更改为after，则效果很好。

.container {
    background-color: lightgray;
    margin: auto;
    width: 500px;
    height: 200px;
    padding: 100px;
}

.icon {
    font-size: 50px;
    cursor: pointer;
    color: red;
}

.icon:hover::before {
    content: '';
    background-color: black;
    padding: 10px;
}

<div class="container">
		<i class="fas fa-exclamation-circle icon"></i>
</div>

将鼠标悬停时将添加黑色背景。您无法休息content，因为那是由FontAwesome用于显示图标的。

.container {
    background-color: lightgray;
    margin: auto;
    width: 500px;
    height: 200px;
    padding: 100px;
}

.icon {
    font-size: 50px;
    cursor: pointer;
    color: red;
}

.icon:hover::before {
    background-color: black;
    padding: 10px;
}

很棒的字体：使用hover :: before时，图标消失了
