如何使DIV滚动而不是BODY？ [英] How to make a DIV scrollable instead of BODY?

问题描述

我希望页面的正文 不可滚动，但正文中的DIV应该可滚动。
我的css文件中有此文件：

I want my page's BODY not to be scrollable but a DIV inside the BODY should be scrollable. I have this in my css file:

body {
overflow:hidden
}

.mainSection {
overflow:scroll
}

---

但是它不起作用，并且DIV不会变成scrollabel（它仅显示两个DIV禁用的滚动条） ！

---

but it doesn't work and the DIV doesn't become scrollabel (it just shows two disabled scroll bars for the DIV)!

推荐答案

.mainSection 需要具有高度。否则，浏览器不知道应该考虑溢出。

.mainSection needs to have a height. Otherwise the browser can not know what it should consider overflow.
