购物车-多元素组合动画css

学习渡一课程多元素组合动画练习。

在我们开发购物车功能时，经常会有点击添加按钮，就会有一个小圆点掉进购物车的动画，如下图所示，今天我们通过css来实现。

首先实现多元素组合动画

直接上代码，可以复制到本地使用：

    <style>
        *{
            padding: 0;
            margin: 0;
        }
        .view{
            width: 400px;
            height: 600px;
            position: relative;
          
            border: 1px solid #dedede;
        }
        .ShoppingCart {
            position: absolute;
            right: 0;
            bottom: 0;
            text-align: center;

        }
        
        .add {
            position: relative;

            animation: move1 0.6s cubic-bezier(0, 0.36, 1, 0.59);
        }
        .ball{
            width: 20px;
            height: 20px;

        }

        @keyframes move1 {

                transform: translateX(350px);
            }
        }
        @keyframes move2 {
            to {
                transform: translateY(510px);
            }
        }
