html - 如何定位 flexbox 元素

<分区>

我正在制作一个用 flex 类构建的网格系统。这是我第一次使用 flex，所以我不太确定它是如何工作的。

到目前为止我制作的网格 is looking like this .

我希望 flexbox 元素 6 看起来像下图:

目前元素 5 和元素 6 各占 50% 的宽度

item5 和 item6 占了 50% 的宽度。我似乎无法改变这一点。我希望第 5 项占 66% 左右，第 6 项占 33%，但元素周围仍有余量。

有人能看出我做错了什么吗？

<style>

.d-flex {
  display: -ms-flexbox!important;
  display: flex!important
}

.d-inline-flex {
    display: -ms-inline-flexbox!important;
    display: inline-flex!important
}
.flex-wrap {
    -ms-flex-wrap: wrap!important;
    flex-wrap: wrap!important
}
.bg-img {
  background-position: center center;
  background-size: cover;
  background-repeat: no-repeat; }

/* CTA Buttons */

.btn-top-left {
  position: absolute;
  left: 10%;
  top: 10%
}

.btn-top-right {
  
}

.btn-center {
  position: absolute;
  left: 50%;
  top: 50%
}

.btn-bottom-left {
  
}

.btn-bottom-right {
  
}

最佳答案

我不会使用宽度百分比。我将最后 2 个元素包装到另一个 div 中，使其 flex ，然后将 flex:1; 添加到第一个元素并将 flex:2; 添加到第二个元素特定的屏幕宽度。

这也会使宽度响应。底线是，避免百分比，对 flexbox 元素使用 flex: 属性。

.wrapper {
  width: 100%;
  min-height: 150px;
  display: flex;
  justify-content: center;
  align-items: center;
}

.one {
  min-height: 150px;
  flex: 2;
  background: red;
}

.two {
  min-height: 150px;
  flex: 1;
  background: green;
}

<div class="wrapper">
  
  <div class="one"></div>
  <div class="two"></div>
  
</div>
