issue with CSS media queries(scrollbar)

Question

I am having problem with css media query in Firefox. It works correct in Chrome like I made two DIVs and want a scrollbar. If I decrease the screen size of firefox upto 800p

Answer 1

Firefox & Opera follows W3C spec which is to include scrollbar width in media queries width (the reason might be to avoid infinite loop as described in a comment here), while Webkit does not (possibly coz they think it makes no sense)

There is a workaround (I've only tested this on FF), apparently if you force scrollbar to be visible all the time, then the width will now be consistent with Webkit. Here's the code:

html
{
   overflow:hidden;
   height:100%;
}
body
{
   position:relative;
   overflow-y:scroll;
   height:100%;
   -webkit-overflow-scrolling:touch; /* So iOS Safari gets the inertia & rubber-band effect */
}

If you want to apply this to FF & Opera only, you can resort to CSS hacks:

/* Firefox */
@-moz-document url-prefix()
{
    html
    {
        overflow:hidden;
        height:100%;
    }
    body
    {
        position:relative;
        overflow-y:scroll;
        height:100%;
        /*-webkit-overflow-scrolling:touch;*/
    }
}

/* Opera */
x:-o-prefocus, html
{
    overflow:hidden;
    height:100%;
}
x:-o-prefocus, body
{
    position:relative;
    overflow-y:scroll;
    height:100%;
}

It goes without saying, the caveat is the scrollbar will be visible at all times, which might be an okay compromise.
