Are scroll bars always the same width in different

问题:

I need to make a CSS adjustment to compensate for a scroll bar. So I was wondering- are scroll bars always the same width in different browsers and operating systems?

I have two tables, one above the other, with matching columns widths (set to percentages). One table needs a scroll bar, so I want to add another column in the table above it to compensate for it, so the columns line up.

Scrollbars aren't even counted the same in different browsers, some of them put them inside the frame, while others put them outside (thus making alignment a real pain).

Try to think of a way of presenting the data where it won't matter.

No, and on some systems their width is user configurable.

SWEET!Here's a solution for anyone who has this same problem. This should be cross-browser compatible too.

Just add a scroll bar to the top table as well, with some extra CSS to hide them.

#topTable{
    overflow: scroll;
    padding-right: 16px;
    padding-bottom: 16px;
    margin-right: -16px;
    margin-bottom: -16px;
}

In theory, all you have to do is make the "16px's" match, so you can do this with the same effect:

#topTable{
    overflow: scroll;
    padding-right: 100px;
    padding-bottom: 100px;
    margin-right: -100px;
    margin-bottom: -100px;
}
