如何处理滚动条换行

Question

我有一个.sidebar和一个.contentdiv，包裹在一个弹性框中。我想使内容可滚动，同时保持侧边栏固定。

约束

• 我不能使用Javascript
• 容器最大宽度必须为 600 像素

问题

如果我相对定位它，侧边栏和内容都会滚动：小提琴

.flex{
  position: relative;
  display: flex;
  flex-direction: row;
  max-width: 600px;
  margin: auto;
  border: 1px solid green;
}
.flex > *{
    border: 1px solid green;
}
.sidebar{
  width: 200px;
}
.content{
  flex: 1;
  overflow-y: auto;
}
.content p{
  font-size: 48px;
}

如果我绝对定位它，滚动条会离开其美丽的右上角以包裹 600px 容器：小提琴

*{
  box-sizing: border-box;
}
.flex-wrapper{
  position: absolute;
  top: 0;
  left: 0;
  right: 0;
  width: 100%;
  height: 100%;
  max-width: 600px;
  margin: auto;
}
.flex{
  display: flex;
  flex-direction: row;
  border: 1px solid green;
  height: 100%;
}
.flex > *{
    border: 1px solid green;
}
.sidebar{
  width: 200px;
}
.content{
  flex: 1;
  overflow-y: auto;
}
.content p{
  font-size: 48px;
}

我该怎么做才能使滚动条保持在屏幕的右边缘，而不是环绕我的固定宽度div？

无需为此使用 Flexbox，只需删除包装器并给侧边栏一个固定位置即可。

此外，我还使用媒体查询来控制两者的左边缘。

html, body {
  margin: 0;
}
* {
  box-sizing: border-box;
}
.sidebar, .content {
  border: 1px solid green;
}
.sidebar {
  position: fixed;
  top: 0;
  bottom: 0;
  left: calc(50% - 300px);
  width: 200px;
}
.content {
  max-width: 400px;
  margin-left: calc(50% - 100px);
}
.content p {
  font-size: 48px;
}
@media (max-width: 600px) {
  .sidebar {
    left: 0;
  }
  .content {
    margin-left: 200px;
  }
}

  <div class="sidebar">
    <ul>
      <li>Home</li>
      <li>About</li>
      <li>Contacts</li>
      <li>Monkeys</li>
      <lI>Pigeons</lI>
    </ul>
  </div>
  <div class="content">
      <p>
        We have got the best monkeys in entire europe.
      </p>
      <p>
        We have also got some really good pigeons.
      </p>
      <p>
        One pigeon scored more than 1500 in 2016 SAT exams.
      </p>
      <p>
        The monkey was quite jealous of him to be honest.
      </p>

        But they are still besties so far... and will be forever
      </p>
  </div>
