Font Awesome CSS Pseudo-elements

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

&#13;
&#13;
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%);
}

与课程fa-arrow-right一起添加课程fa

请务必删除您已应用的额外规则。

.fa-arrow-right:before {
