CSS Flex Box布局:全宽行和列

Question

各位程序员大家好!

我有一个简单的盒子布局,我很乐意使用flexbox实现,但我简直无法理解.它应该看起来像这个图像.

所以基本上是一行和两列,其中行被固定在高度上,比如100px,但是在一个容器中.到目前为止我的代码是:

#productShowcaseContainer {
  display: inline-flex;
  flex-flow: row wrap;
  height: 600px;
  width: 580px;
  background-color: rgb(240, 240, 240);
}

#productShowcaseTitle {
  display: inline-block;
  height: 100px;
  width: 100%;
  background-color: rgb(200, 200, 200);
}

#productShowcaseDetail {
  flex: 3;
  background-color: red;
}

#productShowcaseThumbnailContainer {
  flex: 2;
  background-color: blue;
}

<div id="productShowcaseContainer">
  <div id="productShowcaseTitle"></div>
  <div id="productShowcaseDetail"></div>
  <div id="productShowcaseThumbnailContainer"></div>
</div>

我知道这可以通过多种方式实现,但我更喜欢使用CSS Flex.

你差不多完成了.但是flex: 0 0 <basis>,为列设置声明会阻止它们增长/缩小; 而<basis>参数将定义列的宽度.

此外,您可以使用CSS3 calc()表达式来指定height与标题高度相关的列.

#productShowcaseTitle {
  flex: 0 0 100%; /* Let it fill the entire space horizontally */
  height: 100px;
}

#productShowcaseDetail,
#productShowcaseThumbnailContainer {
  height: calc(100% - 100px); /* excluding the height of the header */
}

#productShowcaseContainer {
  display: flex;
  flex-flow: row wrap;

  height: 600px;
  width: 580px;
}

#productShowcaseTitle {
  flex: 0 0 100%; /* Let it fill the entire space horizontally */
  height: 100px;
  background-color: silver;
}

#productShowcaseDetail {
  flex: 0 0 66%; /* ~ 2 * 33.33% */
  height: calc(100% - 100px); /* excluding the height of the header */
  background-color: lightgray;
}

#productShowcaseThumbnailContainer {
  flex: 0 0 34%;  /* ~ 33.33% */
  height: calc(100% - 100px); /* excluding the height of the header */
  background-color: black;
}

<div id="productShowcaseContainer">
  <div id="productShowcaseTitle"></div>
  <div id="productShowcaseDetail"></div>
  <div id="productShowcaseThumbnailContainer"></div>
</div>

(由于简洁,省略了供应商前缀)

或者,如果您可以更改标记,例如用附加<div>元素包裹列,则可以在不使用calc()如下的情况下实现:

<div class="contentContainer"> <!-- Added wrapper -->
    <div id="productShowcaseDetail"></div>
    <div id="productShowcaseThumbnailContainer"></div>
</div>

#productShowcaseContainer {
  display: flex;
  flex-direction: column;
  height: 600px; width: 580px;
}

.contentContainer { display: flex; flex: 1; }
#productShowcaseDetail { flex: 3; }
#productShowcaseThumbnailContainer { flex: 2; }

#productShowcaseContainer {
  display: flex;
  flex-direction: column;

  height: 600px;
  width: 580px;
}

.contentContainer {
  display: flex;
  flex: 1;
}

#productShowcaseTitle {
  height: 100px;
  background-color: silver;
}

#productShowcaseDetail {
  flex: 3;
  background-color: lightgray;
}

#productShowcaseThumbnailContainer {
  flex: 2;
  background-color: black;
}

<div id="productShowcaseContainer">
  <div id="productShowcaseTitle"></div>

  <div class="contentContainer"> <!-- Added wrapper -->
    <div id="productShowcaseDetail"></div>
    <div id="productShowcaseThumbnailContainer"></div>
  </div>
</div>

只需使用另一个容器来包装最后两个 div。不要忘记使用 CSS 前缀。

#productShowcaseContainer {
   display: flex;
   flex-direction: column;
   height: 600px;
   width: 580px;
   background-color: rgb(240, 240, 240);
}

#productShowcaseTitle {
   height: 100px;
   background-color: rgb(200, 200, 200);
}

#anotherContainer{
   display: flex;
   height: 100%;
}

#productShowcaseDetail {
   background-color: red;
   flex: 4;
}

#productShowcaseThumbnailContainer {
   background-color: blue;
   flex: 1;
}

<div id="productShowcaseContainer">
   <div id="productShowcaseTitle">1</div>
   <div id="anotherContainer">
      <div id="productShowcaseDetail">2</div>
      <div id="productShowcaseThumbnailContainer">3</div>
   </div>
</div>
