javascript - 将字体 ‘Font Awesome’ 升级到版本 5 后图标消失

标签 javascript html css

我已将“Font Awesome”字体升级到版本 5，然后应用程序中的图标消失了。我还有旧的 js 用于向后兼容，但我的复选框不再有图标。

老实说，我不知道这次升级到底发生了什么变化。

谁能帮帮我？

最佳答案

这里有很多地方需要改变。

  • 您正在加载 JS 文件，但如果您在伪元素中包含图标，则最好使用 CSS 链接。

  • 字体名称已从'FontAwesome'更改为Font Awesome\5 Free，您需要添加font-weight: 900 图标也会出现。

这是一个工作示例:

.checkbox {
  padding-left: 20px;
}

.checkbox label {
  display: inline-block;
  position: relative;
  padding-left: 5px;
}

.checkbox label::before {
  content: "";
  display: inline-block;
  position: absolute;
  width: 17px;
  height: 17px;
  left: 0;
  margin-left: -20px;
  border: 1px solid #cccccc;
  border-radius: 3px;
  background-color: #fff;
  -webkit-transition: border 0.15s ease-in-out, color 0.15s ease-in-out;
  -o-transition: border 0.15s ease-in-out, color 0.15s ease-in-out;
  transition: border 0.15s ease-in-out, color 0.15s ease-in-out;
}

.checkbox label::after {
  display: inline-block;
  position: absolute;
  width: 16px;
  height: 16px;
  left: 0;
  top: 0;
  margin-left: -20px;
  padding-left: 4px;
  padding-top: 4px;
  font-size: 11px;
  color: #555555;
}

.checkbox input[type="checkbox"] {
  opacity: 0;
}

.checkbox input[type="checkbox"]:focus+label::before {
  outline: thin dotted;
  outline: 5px auto -webkit-focus-ring-color;
  outline-offset: -2px;
}

  font-family: Font Awesome\ 5 Free;
  content: "\f00c";
