当按钮悬停时，我正在尝试更改SVG的颜色。
我尝试使用button:hover + svg，但这似乎不起作用。
当我运行CSS时，SVG会填充为白色，并且当我将鼠标悬停在按钮上时，它不会起作用。我看到它起作用的唯一方法是，如果我不将初始填充设置为橙色，而是将其设置为黑色。
怎么了？

+是CSS兄弟选择器。 .icon-svg不是您按钮的兄弟，而是孩子。
也将div放在button内是无效的，但是大多数浏览器会使其正常显示。我在这里将其更改为跨度。
尝试使用.box-button:hover .icon-svg代替.box-button:hover+.icon-svg。
.box-button {
border: 1px solid orange;
color: orange;
padding: 15px 0px;
text-align: center;
margin: 5px 5px;
width: 90%;
font-size: 1.2rem;
}
.box-button:hover {
background-color: orange;
color: white;
}
.box-button:hover .icon-svg {
fill: white !important;
}
.icon-svg {
fill: orange;
}<button class="box-button">
