我几乎读过这里所有关于 div 没有并排排列的帖子，但没有一个适用于我。
似乎我在两个街区上都缺少 float:left; 但无论出于何种原因，他们都没有兑现这一点。如果我对右边的容器执行 float:right;，那么它只是将右边的容器推到左边的容器下面。
到目前为止，我已经尝试过 css 属性:
float :左右； 显示:在线； 显示: block ； 左侧导航和右侧容器的宽度
在我看来，“主容器”正在阻止正确的容器向上移动，但是这个 div 位于该容器内。我还尝试了 z-index 和位置。
我做错了什么？

您目前的标记设置如下:
<container>
<left-container>
<left-nav></left-nav>
<right-container></right-container>
</left-container>
</container>
它需要是:
<container>
<left-container>
<left-nav></left-nav>
</left-container>
<right-container></right-container>
</container>
left-container 没有跨越容器的整个宽度。从那里你添加
float: left;
到你的左侧导航和
float: right;
到你右边的容器，你应该准备好了!
