将页脚放在最底端，仅包含绝对内容

时间：2019-01-21 09:14:27

标签： html css footer positioning absolute

现在，我创建的页面或多或少只包含固定内容和绝对内容。创建第一个视口非常容易，因为它的最大高度为100vh。因此，我用margin-top设置了第二部分的样式：100vh。现在一切正常。但是第二部分不再是100vh的高度。高度或多或少是未知的。

现在，我想创建一个新的部分或页脚。但是问题在于它停留在页面顶部。就像没有其他内容一样。我认为这是因为位置：在所有其他元素上都是绝对的。 另外位置：绝对和底部：0不适用于页脚。然后它只是停留在视口的底部，而不是整个页面的底部。

如何设置下一个样式的样式，使其低于其他内容？

我使用position：absolute的原因是使用CSS创建的固定背景。 也许有一种更聪明的方法来使内容与背景重叠而没有绝对位置？

我认为这是解决问题所需的相关代码：


<div class="first">
    Lorem ipsum first page
</div>

<div class="second">

    <p>Some Images here</p>

将所有内容包装在您所定位的div中：绝对而不是将所有元素都设为绝对。

body {
  padding: 0;
  margin: 0;}
.first {
  color: white;
  height: 100vh;
  width: 100vw;
}

.second {
  margin-top: 110vh;
  color: white;
  width: 100vw;
}

footer {
  background-color: coral;
  z-index: 200;
  height: 10em;
  width: 100vw;
}


.background {
  background: radial-gradient(black 15%, transparent 16%) 0 0, radial-gradient(rgba(255, 255, 255, .1) 15%, transparent 20%) 0 1px;
  background-color: #12364a;
  background-size: 12px 12px;
  width: 100vw;
  height: 100vh;
  min-height: 300px;
  position: fixed;
  overflow: hidden;
  background-attachment: fixed;
  z-index: -1;
  }
  .background:after {

  position: absolute;

  bottom: 0;
  left: 0;
  right: 0;
  margin: auto;

我不知道您为什么要添加这么多的CSS并使其变得困难！我从问题中了解的内容可以通过简单的CSS完成。这是一个示例：

body {
  padding: 0;
  margin: 0;
  background: radial-gradient(black 15%, transparent 16%) 0 0, radial-gradient(rgba(255, 255, 255, .1) 15%, transparent 20%) 0 1px;
  background-color: #12364a;
  background-size: 12px 12px;
  background-attachment: fixed;
  color: #fff;
}

footer {
  background-color: coral;
  height: 10em;
  width: 100%;
}
<div class="first">
  Lorem ipsum first page
</div>
<div class="second">

如果您要在.first和.second之间设置100vh的间隔，则：

body {
  padding: 0;
  margin: 0;
  background: radial-gradient(black 15%, transparent 16%) 0 0, radial-gradient(rgba(255, 255, 255, .1) 15%, transparent 20%) 0 1px;
  background-color: #12364a;
  background-size: 12px 12px;
  background-attachment: fixed;
  color: #fff;
}

.first {
  padding-bottom: 100vh;
}

footer {
  background-color: coral;
  height: 10em;
  width: 100%;
}
<div class="first">
  Lorem ipsum first page
</div>
<div class="second">
  <p>Some Images here</p>
