控制柔性容器中垂直排列的柔性物品的宽度

Question

我试图达到标记为"HALF"的框的效果,仅占据宽度的50%(也就是说它们均匀地共享第一行).

基本要求是它们保留在单个容器中.这有可能实现使用flexbox吗？

我试着玩弄flex-grow,flex-shrink以及flex-basis但是我怕我不理解如何使它工作,或者如果它给出的单容器的要求甚至有可能.

考虑这个小提琴:http://jsfiddle.net/GyXxT/270/

div {
  border: 1px solid;
}

.container {
  width: 400px;
  display: flex;
  flex-direction: column;
}
.child {
  
  height: 200px;
}
.child.half {
  flex: 1 1 10em;
  color: green;
}

.child:not(.half) {

  flex-shrink: 2;
  flex-basis: 50%;
  color: purple; 
}

<div class="container">
  <div class="child half">
    HALF
  </div>
  
  <div class="child half">
    HALF
  </div>
  
   <div class="child">
    FULL
  </div>
   <div class="child">
    FULL
  </div>
  <div class="child">
    FULL
  </div>
   <div class="child">
    FULL
  </div>
</div>

Answer 1

而不是flex-direction: column,您可以尝试使用包装 Flexbox flex-wrap: wrap; 你可以设置:

1. flex-basis: 50% 对于半宽div

2. flex-basis: 100% 对于全宽div

看到我box-sizing: border-box在使用flex-basis时调整宽度.

见下面的演示:

div {
  border: 1px solid;
  box-sizing: border-box;
}
.container {
  width: 400px;
  display: flex;
  flex-wrap: wrap;
}
.child {
  height: 200px;
}
.child.half {
  flex-basis: 50%;
  color: green;
}
.child:not(.half) {
  flex-basis: 100%;
  color: purple;
}

<div class="container">
  <div class="child half">
    HALF
  </div>

  <div class="child half">
    HALF
  </div>

  <div class="child">
    FULL
  </div>
  <div class="child">
    FULL
  </div>
  <div class="child">
    FULL
  </div>
  <div class="child">
    FULL
  </div>
</div>

Answer 2

柔性上浆性能- ,,flex-grow 和-只有沿着工作主轴的柔性容器.flex-shrinkflex-basisflex

由于您的容器是flex-direction: column,主轴是垂直的,这些属性控制高度,而不是宽度.

要在列方向容器中水平调整弹性项目大小,您需要该width属性.

(这里有一个更详细的解释:flex-basis和width之间有什么区别？)

要使用单个容器实现布局,请参阅此问题的另一个答案.

如果要保持列方向,则需要将.half元素包装在自己的容器中.

.container {
  display: flex;
  flex-direction: column;
  width: 400px;
}
.container > div:first-child {
  display: flex;
}
.child.half {
  flex: 1 1 10em;
  color: green;
  width: 50%;
}
.child {
  height: 200px;
  width: 100%;
  border: 1px solid;
}
* {
  box-sizing: border-box;
}

<div class="container">
  <div><!-- nested flex container for half elements -->
    <div class="child half">HALF</div>
    <div class="child half">HALF</div>
  </div>
  <div class="child">FULL</div>
  <div class="child">FULL</div>
  <div class="child">FULL</div>
  <div class="child">FULL</div>
</div>
