如何更改图标的内部(白色)颜色 JwtModule吗?

P.S。应用EmailAuthModule并不是答案,因为红色适用于外部颜色,而不适用于内部感叹号白色符号本身。

“真棒”字体版本是:4.7.0。

此图标的感叹号是透明的,因此,可以在其后面添加背景以具有所需的颜色是一个技巧。当然,背景不应该覆盖整个区域,因此我们需要使用渐变来覆盖其中的一部分。

.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>

与V4相同:

.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>


还有SVG版本:

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

为使答案更通用,我们还可以考虑多个背景和径向渐变,以便为任何形状着色。诀窍是在背景上覆盖透明部分而不会溢出。

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>

Temani Afif的答案很好!这是另一种方法;

.fa-exclamation-triangle{
  position: relative;
  z-index:0;
}
.fa-exclamation-triangle:after{
  content: ' ';
  width: 20%;
  height: 70%;
  position: absolute;
  top: 15%;
  left: 40%;
  background: red;
  z-index: -1;
}
<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>
