【发布时间】：2017-04-04 14:15:08
【问题描述】：

我正在用 Html/Css/JavaScript 设计 Messenger，它们的两个侧面包括联系人，另一侧包括消息。我在两侧添加滚动条，但高度不适合屏幕，显示错误且无响应。

如何将滚动条固定在屏幕上，就像它可以随屏幕移动一样响应？

是的，检查 Jsfiddle:- jsfiddle.net/ggshn2da
@OusmaneMahyDiaw ?????
好的，但这不是完整的解决方案，它只是第二个问题的答案......
现在我不接受了？？

【解决方案1】：

我不明白第一个问题，但对于第二个问题，您只需将该 div 移到外面。

<div class="msb-reply clearfix">
    <textarea placeholder="What's on your mind..."></textarea>
    <button><i class="fa fa-file"></i></button>
    <button><i class="fa fa-camera"></i></button>
    <button><i class="fa fa-paper-plane-o"></i></button>
</div>

谢谢你，请您将文件和相机图标与纸飞机图标分开，拜托....
第一个问题是两边的高度不一样，不适合屏幕，比如Facebook Messenger..
