推荐答案
d
是 SVG 2 规范中定义的 SVG几何属性",位于 https://svgwg.org/svg2-draft/paths.html#TheDProperty.Google Chrome 的 Blink 布局引擎是唯一支持此属性的布局引擎,其实现与当前的规范定义不匹配.
d
is an SVG "Geometry Property" defined in the SVG 2 specification at https://svgwg.org/svg2-draft/paths.html#TheDProperty. Google Chrome’s Blink layout engine is the only layout engine to support this property and its implementation doesn’t match the current specification definition.
