html - 黑匣子姿势练习

我有这张图片，我需要回复。
我已经完成了大部分代码，但是在做黑匣子时遇到了一些麻烦。
它必须是：
-在“ redbox”顶部
-在“ bluebox”后面
-在“ blueinbox”顶部

body {
    padding-top: 0 !important;
    padding-bottom: 0 !important;
    padding-top: 0 !important;
    padding-bottom: 0 !important;
    margin:0 !important;
    width: 100% !important;
    -webkit-text-size-adjust: 100% !important;
    -ms-text-size-adjust: 100% !important;
    -webkit-font-smoothing: antialiased !important;
}
.container {
    background-color: #e1e1e1;
    height: 200px;
    width: 400px;
    border: 0;
    margin: auto;
    display: table;
    margin-top: 20px;
    position: relative;
}
.redbox {
    background-color: #fff;
    height: 120px;
    width: 120px;
    margin: 20px 20px 0 0;
    display: table;
    right: 0;
    border-style: solid;
    border-width: 1px;
    border-color: red;
    border-radius: 5px;
    position: absolute;
}
.bluebox {
    background-color: #fff;
    height: 120px;
    width: 120px;
    margin: 60px 60px 0 0;
    display: table;
    right: 0;
    border-style: solid;
    border-width: 1px;
    border-color: blue;
    position: absolute;
    border-left-style: dashed;
}
.blueinbox {
    background-color: #00aeef;
    height: 80px;
    width: 80px;
    margin: 20px 20px 0 0;
    float: right;
}
.ninja {
    color: #fff;
    font-family: "Open Sans", Arial, sans-serif;
    letter-spacing: 2px;
    position: absolute;
    top: 50%;
    left: 50%;
    margin-right: -50%;
    transform: translate(-50%, -50%)
}

<body>
    <div class="container">
        <div class="redbox">
        </div>
        <div class="bluebox">
            <div class="blueinbox">
                <div class="ninja">
                    <p>NINJA!</p>
                </div>
            </div>
        </div>
    </div>

</body>
