Question

我有一个包含20多个区域（路径和多边形）的SVG地图。每个区域都有一个特定的颜色，在地图的html中设置。

问题是因为CSS样式表而忽略了路径的填充颜色。

这是覆盖它的CSS：

path {
    fill: #20487c;
}

下面是一个示例，显示由于CSS而导致蓝色区域不正确的情况。我无法访问CSS样式表，因此我想知道是否有办法在页面的<body>中更正此问题。

/* This is whats overidding colors*/
path {
    fill: #20487c;
}

path:hover, polygon:hover {
  fill-opacity: 1.00 !important;

}

Answer 1

SVG表示属性与针对相同属性的CSS规则之间的优先级如下：从不太重要到更重要：

用户代理默认样式
SVG演示属性
样式表中设置的CSS规则*
style属性
使用!important关键字
在style属性中设置的CSS规则，带有！important

_{*从第3点开始，正常的CSS选择器重要性规则适用。}

因此，为了在标记中获得更大的重要性，您可以将所有SVG表示属性重写为style属性中的CSS规则：

/* This is whats overidding colors*/

path {
  fill: #20487c;
}

path:hover,
polygon:hover {
  fill-opacity: 1.00 !important;
}

但是，当然，最好的做法是重写有罪的CSS，使其仅针对它应该定位的元素。

CSS正在覆盖SVG地图上路径的填充颜色
