我有一个这样的css问题：

我有 3 个 div，想象它们都堆叠在一列中（比如有 3 行的表格），顶部和底部有height: 100px;，position: absolute;例如，它们就像页眉和页脚，它们总是粘在顶部和我表格的底部。

整个表单的高度可以根据表单中的其他元素而有所不同，所以我需要我的中间 div 刚好在其他 2 个 div 之间，如果它不适合它的内容，则滚动。

（例如页眉和页脚是100px高度，表单只是500px高度，中间 div 中的文本非常长） <- 此时中间 div 扩展并拉伸整个表单。

我已经尝试了很多方法来解决这个问题，包括元素的定位、边距、填充，但仍然没有成功......有人可以帮助我吗？谢谢！

你可以这样做：jsFiddle

CSS

.header, .footer {
    background-color: green;
    height: 100px;
    width: 100%;
}
.form {
    height: 300px;
    position: relative;
}
.content {
    position: absolute;
    top: 100px;
    bottom: 100px;
    overflow-y: scroll;
}
.footer {
    position: absolute;
    bottom: 0px;
}

这么简单的一点点JS有什么问题？

var form_height=300, footer_height=100, header_height=100;

document.getElementById('content').style.height=form_height - header_height - footer_height +'px';

只需添加您的代码即可：

    <div class="header"></div>
    <div id="content" class="content">

    </div>
    <div class="footer"></div>
</div>

CSS

.header, .footer {
    background-color: green;
    height: 100px;
}

.form {
    height: 300px; 
}

.content {
    overflow-y: scroll; <!-- I want this to fit between header and footer (in this example to get 100px of height) without using any javascript -->
}
