   用栅格化布局做的一个抽奖机,里面的内容可自行修改。

    

 

    下面就开始分享代码:

<!DOCTYPE html>
<html>
	<head>
		<meta charset="utf-8">

			/* 让article变成容器 */

				grid-template-rows: repeat(6, 1fr);
				grid-template-columns: repeat(6, 1fr);
			}
			/* div样式 */
			div {
				border: 1px saddlebrown solid;
				text-align: center;
				line-height: 150px;
			}
			/* 下面是给盒子调样式 */
			div:nth-child(7) {
