-webkit-mask-attachment Redirect 1

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.


If a -webkit-mask-image is specified, -webkit-mask-attachment determines whether the mask image's position is fixed within the viewport, or scrolls along with its containing block.


-webkit-mask-attachment:  <attachment>[, <attachment>]*


scroll | fixed


If scroll is specified, the mask image scrolls within the viewport along with the block that contains the mask image.
If fixed is specified, the mask image does not scroll with its containing element, instead remaining stationary within the viewport.


body {
    -webkit-mask-image: url('images/mask.png');
    -webkit-mask-attachment: fixed;
