Question

我有这个布局here。我试图让身体内的一切都集中在一起。除了我在链接和下面的代码中尝试过的内容之外，我还尝试在包装器中添加flex-display属性，但这也没有成功。我不完全确定我做错了什么，因为我相信justify-content: center;应该做的蠢事，对吧？

还有一件事：我的<main>上方和下方都有这条丑陋的背景色。如何在不删除<main>标记的情况下解决此问题（这是我发现迄今为止唯一有效的方法）？我应该使用包装器div而不是主标签吗？

Answer 1

从width: 70%元素中删除body。它没有留下任何额外的空间用于居中。

Answer 2

主要部分上方的位是由.summ-box和p标签上的边距引起的。删除边距并用填充替换。

你的身体是70％，它似乎是中心，你的意思是你的身体是100％宽度？

Flexbox：中心主体内容
