Question

我目前正在完成第一年的作业（考试作业）。我有一个绝对定位的文章的问题，这是一个相对定位的文章。为了实现这一点，它似乎必须绝对定位，但是当内容变大时，它不会自动扩展自身的高度。任何人都可以帮助我获得灵活的高度，而不会破坏其余的布局吗？

内容是相对的 content-1等是绝对的。

html

 <div class="content">
        <div class="content-1">
            <article id="info_about"></article>
            <article id="google_map"></article>
            <article id="misc_info" class="clearfix"></article>
        </div>
        <div class="content-2">

        </div>
        <div class="content-3">

        </div>
        <div class="content-4">

        </div>

Answer 1

我不确定为什么要使用单选按钮进行导航。我建议使用简单的jQuery选项卡解决方案http://css-tricks.com/examples/OrganicTabs/重新开始并使用类似的东西，但是我能够通过以下更改让内容与内容一起增长：

<强> HTML 在content-1到content-4中添加一类clearfix。

示例：<div class="content-1 clearfix">

<强> CSS

.content div {
opacity: 0;
-webkit-transition: opacity linear 0.1s;
    -moz-transition: opacity linear 0.1s;
    -o-transition: opacity linear 0.1s;
    -ms-transition: opacity linear 0.1s;
    transition: opacity linear 0.1s;
}

.content-2, .content-3, .content-4{
position: absolute;
top: 0;
}


article#info_about {
width: 530px;
min-height:480px;
background: rgba(0, 0, 0, 0.8);
margin-right: 20px;
float: left;
}

绝对子的相对高度，相对父级
