动画

Layui 内置了几种常见的 CSS3 动画。

示例

  <div class="layui-anim" id="example-anim-element" style="padding: 16px 0;">
  目标元素
</div>
<button class="layui-btn layui-btn-primary" id="example-anim-usage">点击触发动画</button>
<p>旋转动画加自动循环：</p>
<button class="layui-btn">
  <i class="layui-icon layui-icon-loading layui-anim layui-anim-rotate layui-anim-loop"></i>
</button>

<!-- import layui -->
<script>
layui.use(function(){
  var $ = layui.$;
  var elem = $('#example-anim-element');
  var animName = 'layui-anim-down'; // 动画类名
  
  // 通过事件简单演示动画过程
  $('#example-anim-usage').on('click', function(){
    elem.removeClass(animName);
    setTimeout(function(){
      elem.addClass(animName); // 给目标元素追加「往下滑入」的动画
    }); 
  });
});
</script>
  

对需要动画的标签添加 class="layui-anim" 基础类，再追加其他不同的动画类，即可让元素产生动画。
