CSS-居中字体超级图标

font-awesome css html

如何将FontAwesome图标居中放置在正方形内?

此时,除facebook图标外,所有图标都或多或少地被放置在右侧,尤其是soundcloude图标。

我一直在使用“w3schools-社交媒体按钮”的例子,似乎当正方形缩小时就会出现这个问题。

.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;
}

<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>

消除不必要的填充(没有为图标留下空间),并让 width / height / line-height 元素的数量决定其布局。

之前:

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

之后:

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

您还可以从 :hover 各州。

现场示例:

.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;
}

<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>

对 ,可以将图标居中。我已经添加了我的代码片段。建议不要为类编写css fa 这个请为相同的添加新类

.decoration-fa{

    border-radius: 50%;
    background: #F0F0F0;
    color: #282828;
    width:18px;
    height:18px;    
}
