Question

我有一个.sidebar和一个.content div，包含在flexbox中。我想在保持侧边栏固定的同时使内容可滚动。

约束

我无法使用Javascript
容器最大宽度必须为600px

问题

如果我相对定位，侧边栏和内容都会滚动：fiddle

.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，滚动条会留下美丽的右角以包裹600px容器：fiddle

*{
  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;
}

如何让滚动条停留在屏幕的右边缘而不是环绕固定宽度的div？我该怎么做？

Answer 1

不需要使用Flexbox，只需移除包装并将侧栏固定在固定位置。

此外，我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;
  }
}

＆＃13;

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