当指针位于svg图标的任何元素上时，保持鼠标悬停效果

Question

我有一个两种颜色的svg图标，想在鼠标悬停时更改其颜色。

.icotop{
    cursor:pointer;
    position:relative;
    width:30px;
    height:30px;
}

.icotop > .fil0{
    fill:#ccc;
}

.icotop > .fil1{
    fill:white;
}

.icotop:hover{
    fill:red;  // doesn't work
}

.icotop .fil0:hover{
    fill:red;  // this works
}

<svg class='icotop' viewBox="0 0 1.99 1.99">
    <path class="fil0" d="M1.8 1.99l-1.62 0 -0.05 -0.03c-0.06,-0.02 -0.1,-0.07 -0.12,-0.13 -0.02,-0.06 -0.01,-0.23 -0.01,-0.31l0 -0.9c0,-0.15 0,-0.15 0.08,-0.25 0.06,-0.07 0.24,-0.25 0.32,-0.31 0.06,-0.05 0.07,-0.04 0.1,-0.06l1.3 0c0,0 0,0 0.01,0 0.01,0.01 0.02,0.01 0.05,0.02 0.04,0.02 0.08,0.06 0.11,0.11 0.03,0.07 0.02,0.19 0.02,0.27l0 1.18c0,0.15 0.02,0.27 -0.09,0.36 -0.05,0.04 -0.07,0.03 -0.1,0.05z"/>

</svg>

问题在于，当鼠标悬停在fil0上时，fil1的颜色会变回来。

那么当鼠标悬停在fil0的任何元素上时，如何更改icotop的颜色

Answer 1

const path = require('path');
const path2 = "http://example.com/test1/test2/img/1.jpg";
const path3 = "http://example.com/test1/img/1.jpg";

const relativePath = path.relative(path.dirname(path2),path.dirname(path3));
console.log(relativePath); //'../../img'

.icotop{
	cursor:pointer;
	position:relative;
	width:30px;
	height:30px;
}

.icotop > .fil0{
	fill:#ccc;
}

.icotop > .fil1{
	fill:white;
}
/* This */
.icotop:hover .fil0{
	fill:red; 
}
/* instead of these */
.icotop:hover{
fill:red;  
}

.icotop .fil0:hover{
fill:red; 
}
/* end instead of these */

Answer 2

您需要更改CSS规则

.icotop:hover .fil0{ fill:red; // this works }
