< ;head>

  <style>
     #container {
        display: flex;
        flex-wrap: wrap;
     }
  </style>

  <div id="container">
      <!-- 这里放置导航栏、内容区域和侧边栏的代码 -->
  </div>

Next , we can place navigation bar, content area and sidebar in the container.

The code for the navigation bar can be written like this:

<nav>
    <!-- 导航栏的内容 -->
</nav>
<!-- 这里放置内容区域和侧边栏的代码 -->

Content area The code for the sidebar can be written like this:

<nav>
    <!-- 导航栏的内容 -->
</nav>
<main>
    <!-- 内容区域的内容 -->
</main>
<!-- 这里放置侧边栏的代码 -->

The code for the sidebar can be written like this:

<nav>
    <!-- 导航栏的内容 -->
</nav>
<main>
    <!-- 内容区域的内容 -->
</main>
<aside>
    <!-- 侧边栏的内容 -->
</aside>

Now, we can add styles to the Flex container and Flex items.

html, body {

margin: 0;
padding: 0;
height: 100%;

}

container {

display: flex;
flex-wrap: wrap;
height: 100%;

}

nav, main, aside {

flex: 1;
padding: 10px;

}

nav {

background-color: #f1f1f1;

}

main {

background-color: #e1e1e1;

}

aside {

background-color: #d1d1d1;

}
