用css實現(xiàn)轉動的陰陽太極圖
問：如何用css和html畫出旋轉的陰陽太極圖
需要的知識
1.div標簽的運用 2.id選擇器，后代選擇器， 3.簡單的css樣式長，寬，高，背景顏色，浮動，絕對定位，邊框弧度 4.div的布局特點
靜態(tài)的完成效果
開始
HTML部分
<!DOCTYPE html>

<div></div>
<div></div>
<div></div>
</div>
<div id="八卦-描述">道可道，非常道</div>
</div>
</body>
</html>
HTML部分說明（不要吐槽中文id哈哈哈，純屬為了方便講解）
1.其中最外面的id為八卦-wrapper為包住八卦的最大的div 2.id 為八卦的div為上圖中的八卦 3.八卦里面的div為 下圖指示部分 
CSS部分
CSS部分說明
通過改變每個div的大小顏色，浮動的left，top值，改變每個div的border-redius的值來畫這個八卦圖

注意事項
1.id可以用中文 ，但是文件名和路徑不能（最好不要） 2.一定要注意清楚瀏覽其的默認樣式 3.能不寫死就千萬不要寫死，最好用百分比代替像素（防止用戶改變分辨率造成的bug） 4.父元素relative，子元素absolute 5.注意幾個div的偏移位置，可以加boder: 1px,solid,red;來確定位置后調(diào)試 6.第27行代碼為讓八卦轉起來在靜態(tài)八卦中不起作用
讓八卦轉起來
/*先定義一個@keyframes 命名為x*/
@keyframes x {
from {
transform: rotate(0deg);
}
to {
transform: rotate(360deg);
}
}
/*在id="八卦"中添加樣式 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：手機端的轉動的八卦
在原代碼不變的情況下使用
@media(max-width:500px){ }來設置移動端的樣式。
（其中設置的樣式為當在移動端的時候所展現(xiàn)的樣式，沒有在其中設置的樣式默認使用客戶端的樣式）
