html - Div 100% 的视口(viewport)和内容

Question

我有一个包含 2 列的布局。左栏是导航，最终将成为 Canvas 外导航，右栏将包含页眉、内容和页脚。

右边的背景应该是灰色的，左边的背景应该是红色的。

我需要将两列都扩展到视口(viewport)高度，但如果有更多内容，那么它应该转到 100% 的内容。现在它扩展到视口(viewport)大小的 100%，但不是内容。

我试过使用 height:100%; min-height:100%;

我也在使用 Bootstrap 4。

这是我目前的代码:

HTML:

<div class="container-fluid full-height">
    <div class="row full-height">
        <div class="col-xl-2 col-lg-3 col-md-4 col-sm-5 col-xs-8 bg-grey full-height"></div>
        <div class="col-xl-10 col-lg-9 col-md-8 col-sm-12 col-xs-12 bg-red full-height">
            <header class="bg-red"></header>
            <div class="row"></div>
            <footer class="bg-red"></footer>
        </div>
    </div>
</div>

CSS:

html, body {
    height: 100%;
}
.full-height {
    height: 100%;
}
.bg-red {
    background: #CC181E !important;
}
.bg-grey {
    background: #333 !important;
}

任何人将不胜感激。

Answer 1

将类 row-eq-height 添加到您的行中，使列的高度相等。 删除 full-height 类，您不需要它。 看下面的例子，

html,
body {
  height: 100%;
}
.bg-red {
  background: #CC181E;
}
.bg-grey {
  background: #333;
}
.row-eq-height {
  display: -webkit-box;
  display: -webkit-flex;
  display: -ms-flexbox;
  display: flex;
}

<div class="container-fluid ">
  <div class="row row-eq-height full-height">
    <div class="col-xl-2 col-lg-3 col-md-4 col-sm-5 col-xs-8 bg-grey"></div>
    <div class="col-xl-10 col-lg-9 col-md-8 col-sm-12 col-xs-12 bg-red">
      <header class="bg-red">
        Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has
        survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop
        publishing software like Aldus PageMaker including versions of Lorem Ipsum. Why do we use it? It is a long established fact that a reader will be distracted by the readable content of a page when looking at its layout. The point of using Lorem
        Ipsum is that it has a more-or-less normal distribution of letters, as opposed to using 'Content here, content here', making it look like readable English. Many desktop publishing packages and web page editors now use Lorem Ipsum as their default
        model text, and a search for 'lorem ipsum' will uncover many web sites still in their infancy. Various versions have evolved over the years, sometimes by accident, sometimes on purpose (injected humour and the like). Where does it come from? Contrary
        to popular belief, Lorem Ipsum is not simply random text. It has roots in a piece of classical Latin literature from 45 BC, making it over 2000 years old. Richard McClintock, a Latin professor at Hampden-Sydney College in Virginia, looked up one
        of the more obscure Latin words, consectetur, from a Lorem Ipsum passage, and going through the cites of the word in classical literature, discovered the undoubtable source. Lorem Ipsum comes from sections 1.10.32 and 1.10.33 of "de Finibus Bonorum
        et Malorum" (The Extremes of Good and Evil) by Cicero, written in 45 BC. This book is a treatise on the theory of ethics, very popular during the Renaissance. The first line of Lorem Ipsum, "Lorem ipsum dolor sit amet..", comes from a line in
        section 1.10.32. The standard chunk of Lorem Ipsum used since the 1500s is reproduced below for those interested. Sections 1.10.32 and 1.10.33 from "de Finibus Bonorum et Malorum" by Cicero are also reproduced in their exact original form, accompanied
        by English versions from the 1914 translation by H. Rackham. Where can I get some? There are many variations of passages of Lorem Ipsum available, but the majority have suffered alteration in some form, by injected humour, or randomised words
        which don't look even slightly believable. If you are going to use a passage of Lorem Ipsum, you need to be sure there isn't anything embarrassing hidden in the middle of text. All the Lorem Ipsum generators on the Internet tend to repeat predefined
        chunks as necessary, making this the first true generator on the Internet. It uses a dictionary of over 200 Latin words, combined with a handful of model sentence structures, to generate Lorem Ipsum which looks reasonable. The generated Lorem
        Ipsum is therefore always free from repetition, injected humour, or non-characteristic words etc.
