Prevent scroll-bar from adding-up to the Width of page on Chrome

Question

DISCLAIMER: overlay has been deprecated.
You can still use this if you absolutely have to, but try not to.

This only works on WebKit browsers, but I like it a lot. Will behave like auto on other browsers.

.yourContent{
   overflow-y: overlay;
}

This will make the scrollbar appear only as an overlay, thus not affecting the width of your element!

All you need to do is add:

html {
    overflow-y: scroll;
}

In your css file as this will have the scroller whether it is needed or not though you just won't be able to scroll

This means that the viewport will have the same width for both

Probably

html {
    width: 100vw;
}

is just what you want.

You can get the scrollbar size and then apply a margin to the container.

Something like this:

var checkScrollBars = function(){
    var b = $('body');
    var normalw = 0;
    var scrollw = 0;
    if(b.prop('scrollHeight')>b.height()){
        normalw = window.innerWidth;
        scrollw = normalw - b.width();
        $('#container').css({marginRight:'-'+scrollw+'px'});
    }
}

CSS for remove the h-scrollbar:

body{
    overflow-x:hidden;
}

Webkit browsers like Safari and Chrome subtract the scroll bar width from the visible page width when calculating width: 100% or 100vw. More at DM Rutherford's Scrolling and Page Width.

Try using overflow-y: overlay instead.
