html - 将第二个 flex 元素垂直和水平分成两半

Question

谁能告诉我如何像下图那样垂直和水平拆分第二个 flex 元素？

我设法把一个大盒子分成两半，但我没能把它和第二个 flex 元素做成一样。这就是我现在拥有的 -> https://jsfiddle.net/paveu/8c9Ls5s8/

谢谢，

HTML

<div class="desktop">
  <div class="yellow">lorem</div>
  <div class="orange">lorem</div>
  <div class="purple">lorem</div>
  <div class="green">lorem</div>
</div>

CSS

* {
  box-sizing: border-box;
}
main,
div {
  display: flex;
  padding: 1rem;
}

.desktop {
  flex-direction: column;
  flex-wrap: wrap;
  height: 400px;
  width: 100%;
  align-items: center;
  justify-content: center;
  align-content: stretch;

}

.desktop > div {
  flex: 1;
}

div.orange {
  background-color: #FFAD77;
  width: 30%;
  flex: 0 0 70%;
  margin-left: 10px;
}

div.yellow {
  flex: 0 0 100%;
  width: 70%;
  background-color: #FFE377;
}

div.purple {
  width: 30%;
    margin-left: 10px;

  background-color: #FF77C8;
}

@media(max-width: 480px) {
  .desktop > div {
    flex: 1;
    width: 100%;
    margin: 0 auto;
  }
  div.orange {
    order: -1;
    flex: 2;
  }
  div.yellow {
    flex: 5;
  }
  div.purple {
    flex: 1;
  }
}
