我的标题CSS让我很痛苦。它会影响随后发生的事情。我只想在内容中心放置3个链接/按钮。但是当我尝试做到这一点时。无法正常工作。 p
标记或h1
标记无关紧要,始终卡在标头后面。我使用了明确的修复程序,但效果不佳。我不确定为什么下一个div停留在标题后面。而且,当我尝试将CSS赋予行div中的a
标记时。它也没有生效。

将padding-top
添加到您的body
中,并用header
将top
粘贴到top: 0;
。
参见下文:
body {
margin: 0;
font-family: Helvetica, sans-serif;
background-color: #f4f4f4;
padding-top: 80px; /* added padding-top */
}
a {
color: #000;
}
.header {
background-color: #fff;
box-shadow: 1px 1px 4px 0 rgba(0,0,0,.1);
position: fixed;
width: 100%;
top: 0; /* stick to top */
}
.header ul {
margin: 0;
padding: 0;
list-style: none;
overflow: hidden;
background-color: #fff;
}
.header li a {
display: block;
padding: 20px 20px;

似乎您正在尝试使页眉始终位于页面顶部(即使向下滚动),因此您在其CSS中添加了position: fixed
。这种样式使所有其他内容都从页面顶部开始,而不是从标题下面开始。因此,您可以给其下面的div一些margin-top: 80px
,也可以给padding-top: 100px
赋予body
,给top: 0
赋予header
。
如果您不希望在向下滚动时标题保持在页面顶部。那么@Ana Liza Pandac的回答似乎是个好方法。
