动画复选框用 Font Awesome 替换 SVG

Question

我创建了一个 CodePen here, that animates a checkbox. Currently is using a SVG for the tick, how can I replace it with a font? example。

input[type=checkbox] {
  opacity: 0;
  float: left;
}
input[type=checkbox] + label {
  margin: 0 0 0 20px;
  position: relative;
  cursor: pointer;
  font-size: 16px;
  font-family: monospace;
  float: left;
}
input[type=checkbox] + label ~ label {
  margin: 0 0 0 40px;
}
input[type=checkbox] + label::before {
  content: ' ';
  position: absolute;
  left: -35px;
  top: -3px;
  width: 25px;
  height: 25px;
  display: block;
  background: white;
  border: 1px solid #A9A9A9;
}
input[type=checkbox] + label::after {
  content: ' ';
  position: absolute;
  left: -35px;
  top: -3px;
  width: 23px;
  height: 23px;
  display: block;
  z-index: 1;

您可以这样做，并根据需要调整 left、top 和 font-size 值。

input[type=checkbox] + label::after {
    font-family: FontAwesome;
    content: '\f00c';
}

input[type=checkbox] {
    opacity: 0;
    float:left;
}
input[type=checkbox] + label {
    margin: 0 0 0 20px;
    position: relative;
    cursor: pointer;
    font-size: 16px;
    font-family: monospace;
    float: left;
}
input[type=checkbox] + label ~ label {
    margin: 0 0 0 40px;
}
input[type=checkbox] + label::before {
    content: ' ';
    position: absolute;
    left: -35px;
    top: -3px;
    width: 25px;
    height: 25px;
    display: block;
    background: white;
    border: 1px solid #A9A9A9;
}
input[type=checkbox] + label::after {
    font-family: FontAwesome;
    content: '\f00c';
    position: absolute;
    left: -35px;
    top: -3px;
    width: 23px;
    height: 23px;
    display: block;
    z-index: 1;
    -ms-transition: all .2s ease;
    -webkit-transition: all .2s ease;
    transition: all .3s ease;
    -ms-transform: scale(0);
    -webkit-transform: scale(0);
    transform: scale(0);
    opacity: 0;
}
input[type=checkbox]:checked + label::after {
    -ms-transform: scale(1);
    -webkit-transform: scale(1);
    transform: scale(1);
    opacity: 1;
}

<link rel="stylesheet" href="//maxcdn.bootstrapcdn.com/font-awesome/4.3.0/css/font-awesome.min.css">

<form method="post" action="/">
    <fieldset>
        <input id="ham" type="checkbox" name="toppings" value="ham">
        <label for="ham">Yay or Nay</label>
    </fieldset>
</form>

根据 Using Font Awesome Icons without Tags 你可以这样做：

input[type=checkbox] + label::after {
  content: '\f00c';
  font-family: FontAwesome;
  font-size: 20px;
  position: absolute;
  left: -32px;
  top: 0px;
  width: 23px;
  height: 23px;
  display: block;
  z-index: 1;;
  -ms-transition: all .2s ease;
  -webkit-transition: all .2s ease;
  transition: all .3s ease;
  -ms-transform: scale(0);
  -webkit-transform: scale(0);
  transform: scale(0);
  opacity: 0;
}

你当然要用 <link rel="stylesheet" href="//maxcdn.bootstrapcdn.com/font-awesome/4.3.0/css/font-awesome.min.css">
