使用CSS在Flexbox中创建侧边栏 [英] Creating a Sidebar within a flexbox with CSS

问题描述

在我的页面上，我想有一个标题，在它的下面，我想在左侧有一个侧边栏，在右边是一个内容页面.

on my page I want to have a header and below this I want to have a sidebar on the left side and the content page on the right side.

侧边栏的宽度应为X(可能为100像素)，内容页面的其余部分应与整个窗口保持一致.

The sidebar should have a width of X (maybe 100 px) and the content page should have the rest of the full window with.

我开始创建它，但是我的侧边栏和内容页面没有完整的高度.即使将高度设置为100％，也不会填满页面的其余部分.

I started creating this but my sidebar and content page don't have a full height. Even when setting height to 100% the don't fill the rest of the page.

为什么我必须为侧边栏设置最小和最大宽度而不是宽度?设置 width:100px 时，宽度返回70px.

And why do I have to set a min and max width for the sidebar instead of width? When setting width: 100px the width returns 70px.

html {
  height: 100%;
}

body {
  height: 100%;
  margin: 0;
  font-family: Ubuntu;
  background: linear-gradient(#b3ffab, #67fffc);
}

#header {
  height: 30px;
  display: flex;
  align-items: center;
  background: linear-gradient(#444444, #333333);
  color: #bbbbbb;
}

#headerContent {
  margin-left: 10px;
}

#page {
  display: flex;
}

#sideBar {
  min-width: 100px;
  max-width: 100px;
  background: red;
}

#content {
  width: 100%;
  background: blue;
}

<link rel="stylesheet" type="text/css" href="//fonts.googleapis.com/css?family=Ubuntu" />

<div id="header">
  <div id="headerContent">
    Desktop
  </div>
</div>

<div id="page">
  <div id="sideBar">
    <div>
      box 1
    </div>
    <div>
      box 2
    </div>
  </div>
  <div id="content">
    content
  </div>
</div>

推荐答案

您可以灵活设置高度和宽度.

You can set the height and width in a flexible way.

• 高度设置为视口高度减去标题高度的100％.
• 边栏的宽度设置为100px.现在，内容可以扩大以填充屏幕的其余部分.

希望这会有所帮助.
