1 实现思路
实现过程包含顶部的雪糕尖尖部分、中间区域、雪糕小人儿动画部分、底部部分和雪糕棍儿部分。
在这篇教程中，我们将用CSS3制作一个生动的雪糕动画。
- 首先，使用HTML创建雪糕的基础结构，包括雪糕体和雪糕棒。
- 然后，利用CSS3的渐变和圆角属性为雪糕添加颜色和形状。
- 接着，应用关键帧动画（@keyframes）实现雪糕的上下浮动效果，让雪糕看起来栩栩如生。
- 最后，通过CSS的过渡效果（transition）添加一些交互，例如悬停时雪糕会轻微摇摆。让我们开始这个有趣的项目吧！
2 身体部分的实现
这里主要是主体身体的区域部分，主要利用了flex布局、border-radius针对四个边角的圆形实现，box-shadow添加阴影部分。
<!-- HTML5部分 -->
<div class="container"><div class="icecream"><div class="icecream-body"></div></div>
</div>// css3部分
.container {width: 100%;height: 100%;position: relative;display: flex;align-items: center;justify-content: center;
}
.container .icecream {width: 27rem;height: 58rem;display: flex;flex-direction: column;align-items: center;justify-content: center;
}
3 雪糕的尖角顶部实现
这里主要是设定了div元素的高度，设定了色值。重点是父元素的overflow通过hidden的设定，将雪糕顶部不至于超出范围。
<!-- HTML5部分 -->
<div class="icecream-body__slice"></div>// css3部分
.container .icecream .icecream-body__slice {display: flex;border-bottom: 1rem solid #461b19;
}
.container .icecream .icecream-body__slice:nth-child(2n-1) {height: 30%;
}
4 第二区域的实现
凸显雪糕的不同色值，可以让人更有味觉，仍然通过设定高度，设定border-bottom等边框的值，不超出父元素区域，高度适中，要给下面关键区域流出空白区域。
.container .icecream .icecream-body__slice:nth-child(2n-1) {height: 30%;
}
.container .icecream .icecream-body__slice:nth-child(2n) {height: 20%;
}
.container .icecream .icecream-body__slice:nth-child(1) {background: #a9d8ea;
}
.container .icecream .icecream-body__slice:nth-child(2) {background: #ab96db;
}
.container .icecream .icecream-body__slice:nth-child(3) {align-items: center;justify-content: center;background: #fcbad2;
} 
5 中间动画区域实现
中间动画区域，要制作动画，就要有开心的笑脸，笑脸分别由眼睛2个，鼻子一个，眼睛和鼻子分别又有动画展示，还要有鼻涕的流出，体现出六一的儿童氛围。用到的技术点有position定位、transform倾斜、border-radius圆角设定、transform-origin旋转、animation动画等
.container .icecream .icecream-body__slice:nth-child(3) .mouth {position: relative;width: 3rem;height: 2.8rem;margin: 0 1rem;
}
.container .icecream .icecream-body__slice:nth-child(3) .mouth__lip {width: 100%;height: 100%;background: #461b19;border-radius: 30% 30% 50% 50% / 29% 29% 65% 65%;position: absolute;z-index: 1;
}
.container .icecream .icecream-body__slice:nth-child(3) .mouth__saliva {width: 1.5rem;height: 2.5rem;background: #ffffff;border-radius: 1rem;position: absolute;transform-origin: 0 0;z-index: 0;animation: saliva 0.75s cubic-bezier(0.4, 0, 1, 1) infinite alternate;
}
6 尾部雪糕棍儿的实现
尾部雪糕棍儿区域，display: flex;：将雪糕棒子设置为弹性盒模型，以便在需要时可以调整内部元素的布局。border-radius: 0 0 10rem 10rem;：设置雪糕棒子的底部边缘为圆角，使其看起来更加平滑和真实。border: 1.7rem solid #461b19;：设置雪糕棒子的边框，宽度为1.7rem，颜色为深棕色。box-shadow: 2.5rem 2.4rem 0 #d3cec4;：添加阴影效果，使雪糕棒子看起来有深度，颜色为浅灰色，阴影向右和向下偏移。
.container .icecream .icecream-stick {display: flex;height: 25%;width: 10rem;border-radius: 0 0 10rem 10rem;border: 1.7rem solid #461b19;border-top: 0;background: #ffd379;position: relative;box-shadow: 2.5rem 2.4rem 0 #d3cec4;
}
