Question

我正在处理网页布局。我创造了这个。 https://codepen.io/iamgonge/pen/paOxxb

我不明白为什么.container .left-side和.right-side元素从浏览器顶部开始而不是在标题下面。布局不应该是header-＆gt; section（hero） - ＆gt; section（one）？我认为这三个div中的任何一个的顶部都在标题之下，但它们不是。我在这里不明白的是什么？

Answer 1

原因是您已将position: fixed;应用于<header>标记。执行此操作时，您必须考虑标题的高度并按下其他元素以恢复布局。
