Non-standard
      This feature is non-standard and is not on a standards track. Do not use it on production sites facing the Web: it will not work for every user. There may also be large incompatibilities between implementations and the behavior may change in the future.
The overflow-clip-box CSS property specifies relative to which box the clipping happens when there is an overflow. It is short hand for the overflow-clip-box-inline and overflow-clip-box-block properties.
/* Keyword values */ overflow-clip-box: padding-box; overflow-clip-box: content-box; /* Two values */ overflow-clip-box: padding-box content-box; overflow-clip-box: content-box content-box; /* Global values */ overflow-clip-box: inherit; overflow-clip-box: initial; overflow-clip-box: unset;
Note: On Gecko, by default, padding-box is used everywhere, but <input type="text"> and similar use the value content-box. Prior to Firefox 29, this behavior was hardcoded; since then it uses this property that can be used elsewhere too. Note that this property is activated by default only in the UA stylesheet and chrome contexts.

}
function scrollSomeElements() {
  var elms = document.querySelectorAll('.scroll');
  for (i=0; i < elms.length; ++i) {
    elms[i].scrollLeft=80;
  }
}
var elt = document.queryElementsByTagName('body')[0];
elt.addEventListener("load", scrollSomeElements, false);
This property has been proposed to the W3C CSSWG; it is not yet on the standard track but, if accepted, should appear in CSS Overflow Module Level 3.
