这是一个类似动画的结帐操作，仅使用CSS完成。我试图在文本显示后更改圈子的内容以勾选&#10003; - 是否有任何方法可以使用css中的内容标记更改内容。

答案 0 :(得分：2)

将内容（1,2,3个数字）更改为:after个伪元素并在其中设置内容。然后，将其应用于每个圆圈。有了这个，您可以通过更改content:"";将它们包含在动画中 改变＆＃34;检查＆＃34;无论你需要什么。

＆＃13;
＆＃13; 
.mf-loader-circle:after {
  position: absolute;
  width: 100%;
  height: 100%;
  left: 50%;
  top: 50%;
  transform: translate(-50%, -50%);
}
#one:after {
  content: "1";
  -webkit-animation: check1 3s;
  -webkit-animation-fill-mode: forwards;
}
#two:after {
  content: "2";
  -webkit-animation: check2 3s;
  -webkit-animation-delay: 2s;
  -webkit-animation-fill-mode: forwards;
}
#three:after {
  content: "3";
  -webkit-animation: check3 3s;
  -webkit-animation-delay: 3s;
  -webkit-animation-fill-mode: forwards;
}
@-webkit-keyframes check1 {

以下是变更摘要：

  • 从HTML中删除了您圈子中的内容。
  • 为您的所有圈子创建了一个:after伪元素。
.mf-loader-circle:after {
  position:absolute;
  width:100%;
  height:100%;
  left:50%;
  top:50%;
  transform:translate(-50%, -50%);
}

在这里，我使用2D变换将数字定位在中心position:absolute;

  • 使用元素＆＃39;将每个content:"";属性设置为必要的数字。的ID。

  • 为不同的数字创建动画，例如：

#one:after {
  content:"1";
  -webkit-animation: check1 3s;
  -webkit-animation-fill-mode: forwards;
}
@-webkit-keyframes check1{
  from {
    content:"1";
  }
  to {
    content:"check";
  }
}

注意：添加相应的供应商前缀。

答案 1 :(得分：1)

您可以使用:before使用content: 'number';分配每个号码。然后，您可以通过在50%将颜色更改为白色，然后为其指定复选标记值，在关键帧中平滑地设置检查过渡动画。

对于此解决方案，您只需要定义1个关键帧动画。

CSS更改

  • 使用content显示您的数字而不是html内部。

  • 设置关键帧动画，延迟（第一个除外）和填充模式。

    .mf-loader-circle#two:before {
  content: '2';
  animation: changeLetter 2s;
  animation-delay: 1.5s;
  animation-fill-mode: forwards;
}

  • 将颜色更改为白色，然后为其指定复选标记。

    @keyframes changeLetter {
  50% {
    color: white;
  }
  100% {
    content: "\2713";
  }
}
