css - 当指针位于 svg 图标的任何元素上时保持鼠标悬停效果

Question

我有一个双色 svg 图标，想在鼠标悬停时更改它的颜色。

.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>

问题是因为 fil0 的颜色在鼠标悬停在 fil1 上时变回。

那么当鼠标悬停在 icotop 的任何元素上时，如何更改 fil0 的颜色

Answer 1

.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 */
