CSS - 中心字体 - 令人敬畏的图标

Question

如何将FontAwesome图标置于方块内？

此时，除了facebook图标外，所有图标都或多或少地放在右侧，尤其是soundcloude图标。

我一直在使用＆＃34; w3schools - 社交媒体按钮＆＃34;例如，当正方形按比例缩小时，似乎会出现此问题。

＆＃13;

＆＃13;

.fa {
  padding: 15px;
  text-align: center;
  vertical-align:middle;
  text-decoration: none;
  margin: 15px 3px; 
  border-radius: 50%;
  width: 7.5px;
  height: 7.5px;
  font-size: 15px;
  line-height: 7.5px !important;
}

.fa {
  background: #F0F0F0;
  color: #282828;
}


.fa-facebook:hover {
  background: #3B5998;
  color: white;
  line-height: inherit;
}

.fa-youtube:hover {
  background: #bb0000;
  color: white;
  line-height: inherit;
}

.fa-instagram:hover {
  background: #125688;
  color: white;
  line-height: inherit;
}

.fa-soundcloud:hover {
  background: #ff5500;
  color: white;
  line-height: inherit;
}

＆＃13;

<a href="#" class="fa fa-facebook"></a>
<a href="#" class="fa fa-youtube"></a>
<a href="#" class="fa fa-instagram"></a>
<a href="#" class="fa fa-soundcloud"></a>

Answer 1

杀死不必要的填充（不留下图标的空间）并让元素的width / height / line-height确定其布局。

在：

padding: 15px;
width: 7.5px; 
height: 7.5px;
line-height: 7.5px !important;

后：

width: 30px;
height: 30px;
line-height: 30px !important;

您还可以从:hover状态中删除一些冗余样式。

实例：

＆＃13;

＆＃13;

.fa {
  text-align: center;
  vertical-align: middle;
  text-decoration: none;
  margin: 15px 3px;
  border-radius: 50%;
  width: 30px;
  height: 30px;
  font-size: 15px;
  line-height: 30px !important;
}

.fa {
  background: #F0F0F0;
  color: #282828;
}

.fa:hover {
  color: #fff;
}

.fa-facebook:hover {
  background: #3B5998;
}

.fa-youtube:hover {
  background: #bb0000;
}

.fa-instagram:hover {
  background: #125688;
}

.fa-soundcloud:hover {
  background: #ff5500;
}

＆＃13;

<link href="https://cdnjs.cloudflare.com/ajax/libs/font-awesome/4.7.0/css/font-awesome.min.css" rel="stylesheet" />
<a href="#" class="fa fa-facebook"></a>
<a href="#" class="fa fa-youtube"></a>
<a href="#" class="fa fa-instagram"></a>
<a href="#" class="fa fa-soundcloud"></a>

Answer 2

是，您可以将图标居中。 我添加了我的代码段。 建议，请不要为课程fa写css。请为同一个

添加新课程

＆＃13;

＆＃13;

.decoration-fa{
    padding:15px;
    text-align:center;
    text-decoration: none;
    border-radius: 50%;
    background: #F0F0F0;
    color: #282828;
    width:18px;
    height:18px;    
}

.decoration-fa.fa-facebook:hover {
  background: #3B5998;
  color: white;
}

.decoration-fa.fa-youtube:hover {
  background: #bb0000;
  color: white;
}

.decoration-fa.fa-instagram:hover {
  background: #125688;
  color: white;
}

.fa-soundcloud:hover {
  background: #ff5500;
  color: white;
}

＆＃13;

<link href="https://cdnjs.cloudflare.com/ajax/libs/font-awesome/4.7.0/css/font-awesome.min.css" rel="stylesheet"/>
<a href="#" class="fa fa-facebook decoration-fa"></a>
<a href="#" class="fa fa-youtube decoration-fa"></a>
<a href="#" class="fa fa-instagram decoration-fa"></a>
