我正在尝试添加SVG图像(在本例中为比利时的标志)作为SVG路径的填充(实际上是椭圆)。在悬停时,椭圆的填充必须转换为红色。换句话说,填充SVG必须“淡出”。我尝试用CSS做的方式,但SVG模式和转换似乎都不起作用。我试过Chrome和Firefox。
svg ellipse {
fill: url(#img1);
transition: fill 400ms;
}
svg:hover ellipse {
fill: red;
}

<defs>
<pattern x="0" y="0" id="img1" height="480" width="640" viewBox="0 0 640 480">
<g fill-rule="evenodd" stroke-width="1pt">
<path d="M0 0h213.335v479.997H0z" />
<path fill="#ffd90c" d="M213.335 0H426.67v479.997H213.335z" />
<path fill="#f31830" d="M426.67 0h213.335v479.997H426.67z" />
</g>
</pattern>
</defs>
<rect fill="none" stroke="blue" x="1" y="1" width="640" height="480"/>
<ellipse stroke="black" stroke-width="5" cx="400" cy="200" rx="350" ry="150" />
</svg>

你不能像那样转换fill
,因为两个填充不是可以在两者之间平滑插值的东西。
你需要做的是有两个版本的椭圆,一个在另一个之上。然后淡出或淡出顶部。
.visible-on-hover {
transition: opacity 400ms;
opacity: 0;
}
.visible-on-hover:hover {
opacity: 1;
}
