css - Bootstrap 4 - 全高抽屉

Question

我正在开发一个使用 Bootstrap 4 的应用程序。此外，我正在使用 material design framework .我需要这个应用程序占据整个屏幕并使用作为框架一部分的抽屉。我可以通过使用 flexbox 成功地让应用程序占据整个屏幕。但是，我似乎无法让抽屉占据所有可用高度。您可以在 this Fiddle 中查看问题. Fiddle 中的代码如下所示:

<div id="app" class="d-flex flex-column h-100">
  <nav class="navbar sticky-top banner">
    <a class="navbar-brand" href="#">My App</a>
  </nav>

  <div class="d-flex flex-column flex-grow">
    <div class="h-100 flex-grow">
      <div class="bmd-layout-container bmd-drawer-f-l bmd-drawer-overlay">
        <div id="appDrawer" class="bmd-layout-drawer bg-faded">
          <div class="container">
            <header>Hello</header>
            <p>
              This is a longer block of information text.
              Regardless of how long this block of text is,
              the drawer should extend all the to the footer.
            </p>
          </div>
        </div>

        <main class="bmd-layout-content">
          <div class="container">
            <h1>
            Hello
            </h1>

                <button class="btn btn-primary btn-raised" data-toggle="drawer" data-target="#appDrawer">Show Info</button>

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


    <footer>
      <p>Thank you for visiting!</p>
    </footer>
</div>

如何让抽屉占满 nav 和 footer 区域之间的整个高度？

谢谢

一种方法是使包裹 .bmd-layout-container 的元素成为具有 flex-direction: column 的 flex parent，然后设置生成的 .bmd-layout-canvas 类到 flex-grow: 1。

$(document).ready(function () { $('body').bootstrapMaterialDesign(); });

body, html {
    height: 100%;
}

.flex-grow {
    flex: 1 0 auto;
}

.bmd-layout-canvas {
  flex-grow: 1;
}
