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.
Summary
The overflow-clip-box
CSS property specifies relative to which box the clipping happens when there is an overflow.
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.
Initial value | padding-box |
---|---|
Applies to | all elements |
Inherited | no |
Media | visual |
Computed value | as specified |
Animatable | no |
Canonical order | the unique non-ambiguous order defined by the formal grammar |

.scroll { overflow: auto; padding: 0 30px; width: 6em; border: 1px solid black; background: lime content-box; }
.padding-box { overflow-clip-box: padding-box; }
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);
