我在浏览器侧面的div中有一个菜单，我想将它保持在固定位置。但是，菜单可能会超出某些屏幕的高度，并导致无法访问的链接。所以我想在这种情况下使菜单滚动。不幸的是，组合
position：fixed; 溢出：auto; （或滚动）并不真正起作用。即滚动条淡出（不可移动）。有没有办法？ 在此先感谢

菜单类似于在此页面上向右转。只有一点点大。如果您打开该页面并降低浏览器窗口的高度，则部分菜单仍将无法访问。这就是我想要避免的。 并且不，我的解决方案在IE，Chrome，Opera或Firefox中不起作用。
解决方案将这些添加到你的声明：
top：0; bottom：0; / *或高度：100％; * /您可以用较大的值替换零以增加页边距。
I have a menu in a div on the side of the browser and I would like to keep it in the fixed position. However, the menu may exceed height of some screens and that would result inaccessible links. So I would like to make the menu scrollable in such a case. Unfortunately the combination
position: fixed; overflow: auto; (or scroll)doesn't really work. I.e. the scrollbar is faded out (immovable). Is there a way? Thanks in advance
EDIT
The menu is similar to the one to the right up on this page. Only a bit larger. If you open that page and decrease the height of your browser window, part of the menu remains inaccessible. That's what I want to avoid. And no, my solution doesn't work in IE, Chrome, Opera or Firefox.
解决方案Add these to your declarations:
top: 0; bottom: 0; /* or height: 100%; */You can replace the zeroes with larger values to add margins.
