Hide scroll bar, but while still being able to scroll

Question

I want to be able to scroll through the whole page, but without the scrollbar being shown.

In Google Chrome it's:

::-webkit-scrollbar {
    display: none;
}

But Mozilla Firefox and Internet Explorer don't seem to work like that.

I also tried this in CSS:

overflow: hidden;

That does hide the scrollbar, but I can't scroll any more.

Is there a way I can remove the scrollbar while still being able to scroll the whole page?

With just CSS or HTML, please.

Answer 1

Just a test which is working fine.

#parent{
    width: 100%;
    height: 100%;
    overflow: hidden;
}

#child{
    width: 100%;
    height: 100%;
    overflow-y: scroll;
    padding-right: 17px; /* Increase/decrease this value for cross-browser compatibility */
    box-sizing: content-box; /* So the width will be 100% + 17px */
}

JavaScript:

Since the scrollbar width differs in different browsers, it is better to handle it with JavaScript. If you do Element.offsetWidth - Element.clientWidth, the exact scrollbar width will show up.

Or

Using Position: absolute,

#parent{
    width: 100%;
    height: 100%;
    overflow: hidden;
    position: relative;
}

#child{
    position: absolute;
    top: 0;
    bottom: 0;
    left: 0;
    right: -17px; /* Increase/Decrease this value for cross-browser compatibility */
    overflow-y: scroll;
}
