html - 根据剩余空间自动调整 Div 大小(占以下 Div)

Question

我正在尝试将一些 DOM 放在一起，但我真的不确定如何解决以下问题。我基本上需要有一个可见的 .filterArea，并且它上面的区域占用剩余空间。困难在于我希望我的 .filterArea 根据宽度做出响应，但我不知道我预先的总高度。

body {
  background-color: #fff;
}

.mainArea {
  background: red;
  color: white;
}

.filter-area .tags {
  padding: 10px;
}

.tag {
  margin: 5px;
  padding: 5px;
  background-color: #f6f6f6;
  display: inline-block;
}

<div class="container">

  <div class="mainArea">
  <p>
  This is the main area
  </p>
  </div>

  <div class="filterArea" data-bind="component: filterComponent">
    <div class="filter-area">
      <!-- Represent the different tags that can be applied as filters -->
      <div class="tags">
        <div class="tag" data-tag="lessThan" data-bind="click: addTag, dl-filterTagRipple">

        </div>
        <div class="tag" data-tag="between" data-bind="click: addTag, dl-filterTagRipple">
          <span class="name">Between</span>
          <span class="value" data-bind="dl-siformat: arg0">0</span>
          <span class="name">and</span>
          <span class="value" data-bind="dl-siformat: arg1">0</span>
        </div>
        <div class="tag" data-tag="within" data-bind="click: addTag, dl-filterTagRipple">
          <span class="name">Within</span>
        </div>
        <div class="tag" data-tag="empty" data-bind="click: addTag, dl-filterTagRipple">
          <span class="name">Empty</span>
        </div>
      </div>
      <div class="filters scrollable numberFilters filtersEmpty" data-bind="css: filters().length === 0 ? 'filtersEmpty' : ''">
        <div data-bind="dl-filter-scroll-top:$parent"></div>
        <div data-bind="template: { foreach:filters,
                                    name: function(item) { return item.func(); },
                                    afterAdd: showFilter,
                                    beforeRemove: hideFilter  }"></div>
      </div>
    </div>
  </div>

我见过一些解决方案，但它们都依赖于必须知道 .filterArea 的固定高度。在处理完 .filterArea 之后，我可以应用一些 CSS 魔术来根据剩余空间调整顶部部分的大小吗？

Answer 1

您可以使用 CSS flexbox 和一个使用 vh 单位的容器来使总高度成为视口(viewport)的高度。

body {
  background-color: #fff;
}

.container {
   height: 100vh;
   display: flex;
    flex-direction: column;
}

.mainArea {
  background: red;
  color: white;
   flex: 1;
   
}

.filter-area .tags {
  padding: 10px;
}

.tag {
  margin: 5px;
  padding: 5px;
  background-color: #f6f6f6;
  display: inline-block;
}
