我遇到布局问题,尝试了解浮动以及如何定位元素。我对css / html很新。有人可以帮我理解这种布局是如何工作的。一些问题:
1)无法在不破坏布局的情况下更改页脚高度,页脚似乎被向上推。
2)当我通过chrome检查页面时,页脚div包含在'包装内。当它在代码之外时它就是div。
3)向内容div添加填充似乎也打破了布局

我确实使用+ 200px页脚制作了一个+ 200px的填充内容。除了内容上的display:inline-block
以及内容上的box-sizing: border-box;
之外,我们没有更改任何内容。

没有必要为html提供宽度和高度为100%,而css宽度中的div或div默认为100%。您只能在需要时提及宽度。
为页脚提供高度只需添加清除:两者都是页脚选择器
footer {background-color:orange; clear:both; height:50px;}
这将解决问题1&amp; 2.当您添加填充时,设计会中断,因为每次添加宽度时,它都会保持添加到已经赋予相同div或元素的当前宽度。这可以通过重新调整元素宽度或使用box-sizing:border-box来解决。
