我在项目上使用了几次Word Awesome SVG。现在我正在尝试创建一个按钮,这样当它悬停在箭头上时,图标右侧会出现指向右侧的图标。当按钮悬停在上方时,只有一个空白方块,图标应该是,并且图标显示在左侧,带有文本。
使用
display:none
删除了按钮文字右侧的空白图标。
如何使图标显示在空白方块中?
这是代码
window.FontAwesomeConfig = {
searchPseudoElements: true
}

.fa-arrow-right:before {
font-family: 'Font Awesome 5 Solid';
content: "\f061";
font-weight: 900;
}
.btn-4 {
border-radius: 50px;
border: 3px solid #fff;
color: #fff;
overflow: hidden;
}
.btn-4:active {
border-color: #17954c;
color: #17954c;
}
.btn-4:hover {
background: #24b662;
}
.btn-4:before {
position: absolute;
height: 100%;
font-size: 125%;
line-height: 3.5;
color: #fff;
-webkit-transition: all 0.3s;
-moz-transition: all 0.3s;
transition: all 0.3s;
}
.btn-4:active:before {
color: #17954c;
}
/* Button 4a */
.btn-4a:before {
left: 130%;
top: 0;
}
.btn-4a:hover:before {
left: 80%;
}
/* Button 4b */
.btn-4b:before {
left: -50%;
top: 0;
}
.btn-4b:hover:before {
left: 10%;
}

要使用font-awesome,你必须定义font-family,并在内容中引入很棒的字体cheatsheet。
字体家族:
font-family: FontAwesome;
内容:
content: '/f2bb' // exemple
Cheatsheet - https://fontawesome.com/cheatsheet
h1 {
margin: 25px auto;
font-size: 40px;
text-align: center;
font-family: sans-serif;
}
.box {
width: 150px;
height: 150px;
background-color: #CD5C5C;
margin: 0 auto;
position: relative;
}
.box::after {
content: "\f0fc";
font-family: FontAwesome;
font-size: 100px;
position: absolute;
top: 50%;
left: 50%;
transform: translate(-50%, -50%);
}
