我将以下图形嵌入到标记中:
<div id="svgContainer" >
<svg xmlns="http://www.w3.org/2000/svg"
xmlns:xlink="http://www.w3.org/1999/xlink"
preserveAspectRatio="xMaxYMin meet"
viewBox="0 0 1800 1111">
<defs>
<linearGradient id="gradient" x1="0" y1="00%" x2 ="0" y2="100%">
<stop stop-color="black" offset="0"/>
<stop stop-color="white" offset="1"/>
</linearGradient>
<mask id="masking" maskUnits="objectBoundingBox" maskContentUnits="objectBoundingBox">
<rect y="0.3" width="1" height=".7" fill="url(#gradient)" />
<circle cx=".5" cy=".5" r=".5" fill="white" />
</mask>
</defs>
<foreignObject width="100%" height="100%"
id="coverImageContainer" mask="url(#masking)">
<img id="coverImage" src="/images/v3/eminem-cover.jpg" />
</foreignObject>
</svg>
</div>
在Safari和Chrome上,使用图形中心作为适当的锚点,图形会适当调整大小。但是,在Firefox上,图像会调整大小,因为我已将preserveAspectRatio
元素上的svg
设置为xMinYMax meet
。是什么导致了这种行为的差异?
