伙計們，我在 img 標簽中有一個 svg，我希望當我的按鈕帶有“焦點”時，svg 顏色會改變

我對此進行了一些研究，據我所知，我無法做我想做的事，有人知道這是否可能嗎？
如果我嘗試更改 svg 內的顏色，它可以作業，但是焦點必須在 svg 上，而不是在我的按鈕上
簡而言之，當焦點在我的按鈕上時，我想更改 svg 的顏色
.filter-green path:focus{
filter: invert(100%) sepia(0%) saturate(2%) hue-rotate(36deg) brightness(107%)
contrast(101%);
}
.someclassname{
fill: #fff;
}
svg:hover {
fill: #fff;
}
path:hover{
fill: #fff;
}
uj5u.com熱心網友回復：
應該將按鈕上的focus(or hover) 和受影響的元素設定為它的子元素。這里似乎也!important有必要。
.btn:hover svg path {
fill: #ff0000 !important;
transform: scale(2);
