html - 使用 Flexbox 使盒子并排 CSS

Question

我正在努力使 explanation 和 participation 类是 flexboxes，但彼此并排。而在它们下方，benefits 和 requirements 将相互堆叠。

我尝试使用flex-direction:row;作为explanation和participation部分，然后切换到flex- direction: column; 对于其余部分，但这不起作用。我需要帮助来弄清楚这是可以做到的。另外，我无法更改我的 HTML。

.main {
  display: flex;
}

.benefits {
  flex-direction: column;
}

.requirements {
  flex-direction: column;
}

<main class="main" id="zen-supporting" role="main">
  <section class="explanation" id="zen-explanation" role="article">
    <h3>What's This About?</h3>
    <p>There</p>
  </section>

  <section class="participation" id="zen-participation" role="article">
    <h3>Participation</h3>
    <p>Download</p>
  </section>

  <section class="benefits" id="zen-benefits" role="article">
    <h3>Benefits</h3>
    <p>Why participate?</p>
  </section>

  <section class="requirements" id="zen-requirements" role="article">
    <h3>Requirements</h3>
    <p>gtgtgtg</p>
  </section>

Answer 1

您可以使用 wrapping flexbox 并使用 flex-basis 来调整布局 - 请参见下面的演示:

main{
   display: flex; 
   flex-wrap: wrap; /* wrapping flexbox */
   /* flex-direction is row by default - so not specified */
}

.explanation, .participation{
   flex-basis: 50%; /* occupy half a row (flex line) */
}

.benefits, .requirements{
   flex-basis: 100%; /* occupy the whole row (flex line) */
}

main > section { /* styling for illustration */
  border: 1px solid;
  box-sizing: border-box;
}

<main class="main" id="zen-supporting" role="main">
  <section class="explanation" id="zen-explanation" role="article">
    <h3>What's This About?</h3>
    <p>There</p>
  </section>

  <section class="participation" id="zen-participation" role="article">
    <h3>Participation</h3>
    <p>Download</p>
  </section>

  <section class="benefits" id="zen-benefits" role="article">
    <h3>Benefits</h3>
    <p>Why participate?</p>
  </section>

  <section class="requirements" id="zen-requirements" role="article">
    <h3>Requirements</h3>
    <p>gtgtgtg</p>
  </section>
</main>
