    The mask element in CSS allows users to alter the visibility of an item by either partially or fully hidding the item. This is accomplished by either masking or clipping the image at specific points.


    mask: <uri> | none | inherit


    If the value is a URI value, the element pointed to by the URI is used as an SVG mask.


    .target { mask: url(#c1); }
    .anothertarget { mask: url(resources.svg#c1); }

    Gecko notes

    [*] Starting in Gecko 10.0 (Firefox 10.0 / Thunderbird 10.0 / SeaMonkey 2.7), the default color space when handling masks is sRGB; previously, the default (and only supported color space) was linearRGB. This changes the appearance of mask effects, but brings Gecko into compliance with the second edition of the SVG 1.1 specification.
