Question

我必须遗漏一些明显的东西。我试图在Bootstrap 4中实现Holy Grail布局的衍生物。

代替标题 - ＆gt;左列，流体中心，右列 - ＆gt;页脚，我希望我的页眉和页脚在Fluid Center Column中。显然，顶部的标题，底部的页脚和中心的流体含量。并且所有列的高度相同。

-----------------------------------------------------
|          |       Header              |            |
|          |---------------------------|            |
|  LEFT    |                           |  RIGHT     |
|  PANEL   |       MAIN CONTENT        |  PANEL     |
|          |                           |            |
|          |                           |            |
|          |---------------------------|            |
|          |       Footer              |            |
-----------------------------------------------------

代码的骨骼如下所示。我正在努力的方法是让页眉和页脚正确显示在流体中心列中。我觉得答案在于FlexBox，但是我无法理解如何做到这一点！

确保中间列为flex-column，然后使用flex-grow:1作为主要内容。在这个例子中，我只在较大的屏幕上使用侧边栏固定宽度，但您可以决定更改它。

<div class="container-fluid h-100">
    <div class="row h-100">
        <!-- left sidebar -->
        <div class="col-md-2 fixed">

        </div>
        <!-- center content -->
        <div class="col fluid d-flex flex-column">
            <nav id="topNav" class="navbar"> 
            </nav>

            <!-- main content -->
            <div class="row flex-grow">

            </div>

            <footer class="navbar navbar-toggleable-xl navbar-faded navbar-light">
            </footer>

        </div>
        <!-- right sidebar -->
        <div class="col-md-2 fixed">

        </div>
    </div>
</div>

CSS

html {
    height: 100%;
}

body {
    min-height: 100vh;
}

/* fixed and fluid only on sm and up */
@media (min-width: 576px) {
    .fixed {
        flex: 0 0 200px;
        min-height: 100vh;
    }
    .col .fluid {
       min-height: 100vh;
    }
}

.flex-grow {
   flex:1;
}

注意：请注意，在classic "holy grail" layout中，术语“固定”是指宽度，不是在position:fixed中的位置。但是，通过一些调整，可以获得固定的宽度和位置。例如，这是一个替代的“圣杯”布局，左侧栏固定宽度和位置：https://www.codeply.com/go/s90QZLC0WT
