Make DIV fixed inside a scrollable DIV
提问by williamtroup
Does anyone now how to make a DIV inside another DIV that is scroll-able fixed, so that no matter how much I scroll by, the DIV always stays in the same place?
现在有没有人如何在另一个可滚动固定的 DIV 中制作 DIV，这样无论我滚动多少，DIV 始终保持在同一个位置？
Any help would be greatly appreciated.
任何帮助将不胜感激。

Try this out:
试试这个：
<style type="text/css">
.scrollable {
width: 200px;
height: 200px;
background: #333;
overflow: scroll;
}
.fixed {
position: absolute;
top: 180px;
width: 200px;
height: 20px;
background: #fa2;
}
</style>
<div class="scrollable">
im scrollable<br><br>
im scrollable<br><br>
im scrollable<br><br>
im scrollable<br><br>
im scrollable<br><br>
im scrollable<br><br>
<div class="fixed">and I'm fixed</div>
</div>

I would recommend absolutely positioning the div overthe scrollable div. It wont be inthe scrollable div, because it doesn't need to be.
我会建议在div绝对定位在滚动股利。它不会在可滚动的 div 中，因为它不需要。
