更改字体图标的颜色

font-awesome background colors css html

Haradzieniec · 技术社区 · 6 年前

如何更改图标的内部(白色)颜色 <i class="fa fa-exclamation-triangle"></i> ?

P.S.申请 <i class="fa fa-exclamation-triangle" style="color:red"></i> 不是答案,因为红色适用于外部颜色,而不是内部感叹号白色本身。

字体版本是:4.7.0。

这个图标的感叹号是一个透明的部分,所以一个技巧是在它后面添加一个背景以获得所需的颜色。当然,背景不应该覆盖整个区域,所以我们需要用梯度来覆盖它的一部分。

.fa-exclamation-triangle {
  background:linear-gradient(red,red) center bottom/20% 84% no-repeat;
}

<link rel="stylesheet" href="https://use.fontawesome.com/releases/v5.3.1/css/all.css">
<i class="fas fa-exclamation-triangle fa-7x"></i>
<i class="fas fa-exclamation-triangle fa-4x"></i>
<i class="fas fa-exclamation-triangle fa-2x"></i>

V4也是这样:

.fa-exclamation-triangle {
  background:linear-gradient(red,red) center /20% 70% no-repeat;
}

<link href="https://stackpath.bootstrapcdn.com/font-awesome/4.7.0/css/font-awesome.min.css" rel="stylesheet">
<i class="fa fa-exclamation-triangle fa-5x"></i>
<i class="fa fa-exclamation-triangle fa-4x"></i>
<i class="fa fa-exclamation-triangle fa-2x"></i>

.fa感叹号三角形{
background:linear-gradient(红色,红色)中底/20%84%无重复;

<script defer src="https://use.fontawesome.com/releases/v5.3.1/js/all.js" ></script>
<i class="fas fa-exclamation-triangle fa-7x"></i>
<i class="fas fa-exclamation-triangle fa-4x"></i>
<i class="fas fa-exclamation-triangle fa-2x"></i>

更新

以下是一些图标示例:

.fa-exclamation-triangle {
  background:linear-gradient(red,red) center bottom/20% 84% no-repeat;
}
.fa-ambulance {
 background:
  linear-gradient(blue,blue) 25% 30%/32% 45% no-repeat, 
  radial-gradient(green 60%,transparent 60%) 15% 100%/30% 30% no-repeat,
  radial-gradient(green 60%,transparent 60%) 85% 100%/30% 30% no-repeat;
}
.fa-check-circle {
  background:radial-gradient(yellow 60%,transparent 60%);
}
.fa-angry {
 background: 
  radial-gradient(red 60%,transparent 60%) 25% 40%/30% 30% no-repeat,
  radial-gradient(red 60%,transparent 60%) 75% 40%/30% 30% no-repeat;
}

<link rel="stylesheet" href="https://use.fontawesome.com/releases/v5.3.1/css/all.css">
<i class="fas fa-exclamation-triangle fa-7x"></i>
<i class="fas fa-ambulance fa-7x"></i>
<i class="fas fa-check-circle fa-7x"></i>
<i class="fas fa-angry fa-7x"></i>
