问：如何用css和html画出旋转的阴阳太极图
需要的知识
1.div标签的运用 2.id选择器，后代选择器， 3.简单的css样式长，宽，高，背景颜色，浮动，绝对定位，边框弧度 4.div的布局特点
静态的完成效果
开始
HTML部分
<!DOCTYPE html>
<html lang="zh">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>太极页面</title>
</head>
<body>
<div id="八卦-wrapper">
<div id="八卦">
<div></div>
<div></div>
<div></div>
<div></div>
<div></div>
<div></div>
</div>
<div id="八卦-描述">道可道，非常道</div>
</div>
</body>
</html>
HTML部分说明（不要吐槽中文id哈哈哈，纯属为了方便讲解）
1.其中最外面的id为八卦-wrapper为包住八卦的最大的div 2.id 为八卦的div为上图中的八卦 3.八卦里面的div为 下图指示部分 
CSS部分
CSS部分说明
通过改变每个div的大小颜色，浮动的left，top值，改变每个div的border-redius的值来画这个八卦图

注意事项
1.id可以用中文 ，但是文件名和路径不能（最好不要） 2.一定要注意清楚浏览其的默认样式 3.能不写死就千万不要写死，最好用百分比代替像素（防止用户改变分辨率造成的bug） 4.父元素relative，子元素absolute 5.注意几个div的偏移位置，可以加boder: 1px,solid,red;来确定位置后调试 6.第27行代码为让八卦转起来在静态八卦中不起作用
让八卦转起来
/*先定义一个@keyframes 命名为x*/
@keyframes x {
from {
transform: rotate(0deg);
}
to {
transform: rotate(360deg);
}
}
/*在id="八卦"中添加样式 animation: x 10s linear infinite;*/
#八卦 {
width: 400px;
height: 400px;
border-radius: 200px;
position: relative;
overflow: hidden;
animation: x 10s linear infinite;/*添加此行*/
box-shadow: 0px 0px 5px 0px rgba(0, 0, 0, 1);
}

拓展：手机端的转动的八卦
在原代码不变的情况下使用
@media(max-width:500px){ }来设置移动端的样式。
（其中设置的样式为当在移动端的时候所展现的样式，没有在其中设置的样式默认使用客户端的样式）
