顾名思义，十五拼图就是将游戏画面中的数字从上到下，从左到右按顺序从1到15排列下来，看起来很简单，但是玩起来不容易。

css代码

body {
  font-family: cursive;
  font-size: 14pt;
  text-align: center;
}

#puzzlearea {
  height: 400px;
  margin: 0 auto;
  position: relative;
  width: 400px;
}

.highlight {
  border-color: red;
  cursor: pointer;
}

.puzzletile {
  background-image: url("../background.jpg");
  border: 5px solid black;
  position: absolute;
}

.highlight, #output {
  color: red;
}

.puzzletile, #output {
  font-size: 40pt;
}
