fill

fill 属性には使われ方により2つの意味があります.  1つは図形やテキストに使われた場合で，その要素を塗りつぶす色を意味します．もう1つはアニメーションに使われた場合で，そのアニメーションの最終状態を定義します．

呈示属性(presentation attribute)として全ての要素に適用可能ですが，実際に影響があるのは次の11の要素です: <altGlyph>, <circle>, <ellipse>, <path>, <polygon>, <polyline>, <rect>, <text>, <textPath>, <tref>, and <tspan>.

アニメーションとしては次の5つの要素で使われています: <animate>, <animateColor>, <animateMotion>, <animateTransform>, and <set>.
