隐藏/影响div的标题出现在它之后

问题描述 投票：0回答：2

我的标题css给了我痛苦。它正在影响它之后发生的事情。我只想在内容的中心放置3个链接/按钮。但是当我试着去做的时候。不能正常工作。 p标签或h1标签无关紧要，始终卡在标头后面。我使用了明确的修复，但不是很有效。我不确定为什么下一个div卡在标题后面。而且当我尝试将css给a标签时，它位于行div内。它也没有生效。

将padding-top添加到你的body并用header将top粘贴到top: 0;。

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;
  border-right: 1px solid #f4f4f4;
  text-decoration: none;
}

.header li a:hover,
.header .menu-btn:hover {
  background-color: #f4f4f4;
}

.header .logo {
  display: block;
  float: left;
  font-size: 2em;
  padding: 10px 20px;
  text-decoration: none;
}

/* menu */

.header .menu {
  clear: both;
  max-height: 0;
  transition: max-height .2s ease-out;
}

/* menu icon */

.header .menu-icon {
  cursor: pointer;
  display: inline-block;
  float: right;
  padding: 28px 20px;
  position: relative;
  user-select: none;
}

.header .menu-icon .navicon {
  background: #333;
  display: block;
  height: 2px;
  position: relative;
  transition: background .2s ease-out;
  width: 18px;
}

.header .menu-icon .navicon:before,
.header .menu-icon .navicon:after {
  background: #333;
  content: '';
  display: block;
  height: 100%;
  position: absolute;
  transition: all .2s ease-out;
  width: 100%;
}

.header .menu-icon .navicon:before {
  top: 5px;
}

.header .menu-icon .navicon:after {
  top: -5px;
}

.header .menu-btn {
  display: none;
}

.header .menu-btn:checked ~ .menu {

  transform: rotate(45deg);
}

.header .menu-btn:checked ~ .menu-icon:not(.steps) .navicon:before,
.header .menu-btn:checked ~ .menu-icon:not(.steps) .navicon:after {
  top: 0;
}

好像你试图让标题始终保持在页面顶部（即使向下滚动），所以你在它的CSS中添加了position: fixed。此样式使所有其他内容从页面顶部开始，而不是从标题下方开始。所以你可以给它下面的div给一些margin-top: 80px，或者你可以将padding-top: 100px给body和top: 0给header。

如果您不希望在向下滚动时页眉保留在页面顶部。然后@Ana Liza Pandac回答似乎是一个很好的方法。
