前提问题：实现可视化大屏的布局

解决过程：使用了display布局，完成了以上布局要求

解决结果：

html:

<div class="moduleShow">
    <!-- 头部区域 -->
    <div class="headerModule"></div>
    <div class="mainModule">
        <!-- 左侧区域 -->
        <div class="leftModule">
            <div class="leftMTop"></div>
            <div class="leftMBottom"></div>
        </div>
        <!-- 中间区域 -->
        <div class="centerModule">
            <div class="centerMTop"></div>
            <div class="centerMCenter"></div>
            <div class="centerMBottom">
                <div class="centerMBL"></div>
                <div class="centerMBR"></div>
            </div>
        </div>
        <!-- 右侧区域 -->
        <div class="rightModule">
            <div class="rightMTop"></div>
            <div class="rightMCenter"></div>
            <div class="rightMBottom"></div>
