更改 Font Awesome 图标的颜色 [英] Change the color of Font Awesome's icon

问题描述

如何改变图标的​​内部(白色)颜色<i class="fa fa-exclamation-triangle"></i> ?

How to change the inner (white) color of the icon <i class="fa fa-exclamation-triangle"></i> ?

附言应用 <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，不是内部感叹号白色标志本身.

P.S. Applying <i class="fa fa-exclamation-triangle" style="color:red"></i> is not an answer, as the red color applies to the outer color, not to the inner exclamation white sign itself.

Font Awesome 版本是:4.7.0.

推荐答案

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着色.当然，背景不应该覆盖整个区域，所以我们需要使用渐变来只覆盖它的一部分.

The exclamation mark of this icon is a transparent part, so a trick is to add a background behind it to have the needed coloration. Of couse, the background shouldn't cover the whole area so we need to use a gradient to cover only a part of it.

.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 相同的事情:

The same thing with the V4:

.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

为了使答案更通用，我们还可以考虑多个背景和径向渐变，以便为任何类型的形状着色.诀窍是用背景覆盖透明部分而不溢出.

To make the answer more generic we can also consider multiple background and radial-gradient in order to color any kind of shape. The trick is to cover with the background the transparent part without overflowing.

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>
