推荐答案
使用CSS在body元素上设置边距

可能您需要 IFRAME
尝试自定义此代码以满足您的需求:

May be you need IFRAME
try to customize this code to fulfill your needs :

The content of IFRAME is rest in another file , so place the center content in that file.
EDIT : As you mentioned that you want to use browser scroll bar the only way that remains is using a very old html tag which is frameset
try making a HTML file like this :
<html>
<frameset rows="25%,50%,25%">
<frame src="frame_a.htm" />
<frame src="frame_b.htm" />
<frame src="frame_c.htm" />
</frameset>
</html>
如果frame_b的内容很大，那么浏览器将向其中添加滚动条，并且我确保它是浏览器自己的滚动条;)如果您希望隐藏边框，请尝试研究一下框架集.
但是我记得几年前他们说过不要使用框架集，因为我们将来不会支持它们，但是我仍然看到它们支持它们！
希望这会有所帮助.
if the content of frame_b is large then the browser will add a scroll bar to it and I ensure you that it is browsers own scrollbar ;) if you want the borders to be hidden, try to research about the framesets.
But I remember that several years ago they said that do not use framesets because we are going to not to support them in the future, but I still see that they support them!
Hope this helps.
