困了累了敲代码，提神醒脑--写一些推箱子小游戏

好久没敲代码了，前几天也睡不好，怎么办，折腾自己一下就好了，反正头发多。而且我这个初学者哪能在乎头发哪，距离强者的路还远得很。

我也不是很想写，主要是闲的无聊，再加上技术差，就更不想写了，可是这整宿整宿的睡不着觉，难受啊，白天还贼精神，估计哪天我就猝死了。好了，我把我的代码发一下，很乱，一开始写的全是bug，改了好长时间才改好，这都由于我还是个初学者。

这是HTML：

<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <meta http-equiv="X-UA-Compatible" content="ie=edge">
    <title>Document</title>
    <link rel="stylesheet" href="push.css">
</head>
<body>
    <div>

        <p></p>
        <p></p>
    </div>
</body>
<script src="push.js"></script>

　　

这是CSS：（写的不好看）

*{
    margin: 0;
    padding: 0;
}
div{
     400px;
    height: 280px;
    border: solid 40px #222;
    position: absolute;
    top: 100px;
    left: 300px;
    border-radius: 50px;
    background-color: rosybrown;
}
.wall{
    box-sizing: border-box;
    border-radius: 2px;
     40px;
    height: 40px;
    position: absolute;
    background: red;
    border: white 2px solid;
}
.target{
    box-sizing: border-box;
    border-radius: 50%;
     40px;
    height: 40px;
    position: absolute;
    background: brown;
    border:#222 2px solid;
}
.box{
    box-sizing: border-box;
    border-radius: 4px;
     40px;
    height: 40px;
    position: absolute;
    background: #333;
    border:#222 2px solid;
    font-size: 32px;
    color: white;
    line-height: 28px;
    text-indent: 4px;
    letter-spacing: 10px;
    z-index: 2;
}
img{
    display: block;
    box-sizing: border-box;
    border-radius: 2px;
    position: absolute;
     40px;
    height: 40px;
    top: 120px;
    left: 120px;
    position: absolute;
    z-index: 3;
}

function missionSucess(obj1,obj2){
    var n=0;
    for(var i = 0;i<obj1.length;i++){
        for(var j=0;j<obj2.length;j++){
            if(obj1[i].offsetLeft==obj2[j].offsetLeft&&obj1[i].offsetTop==obj2[j].offsetTop){
                n++;
                console.log(n);
                if(n==obj1.length){
                    alert("YOU WIN!");
                }
            }
        }
    }
}

　　可以执行一下missionSuccess（），让游戏更完整一些。不过我只是个初学者，都是想到哪就桥到哪。出现bug了再去改，而且格式不符合规范，还在改进。

我最想做的就是能睡个好觉，不要半夜睡不着或是半夜醒过来，我才二十出头。不想刚挣点钱就开始留遗产。
