HTML部分源代码如下：
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <title>弹跳的小球</title> <link rel="stylesheet" href="style.css"> </head> <body> <div class="box"> <div class="ball"></div> <div class="shadow"></div> </div> </body> </html>
CSS部分源代码如下：
