我有一个带有图标的容器，该图标应该执行两个功能：
- 具有按钮的作用（可通过键盘/屏幕阅读器等访问）
- 悬停/聚焦时变红
当我直接在标记中使用 SVG 时，悬停效果可以按预期工作，但我无法像使用 img 标签时那样为 SVG 分配按钮角色：
.container {

width: 400px;
background-color: lightblue;
position: relative;
}
.favourite-icon {
position: absolute;
top: 16px;
right: 16px;
}
.favourite-icon:hover {
fill: red;
}
<div class="container">

但是，当我使用 img 标签时，我可以通过 src 属性使用 SVG，为 img 分配按钮角色，但无法在悬停状态下达到预期结果（SVG 保存在其自己的文件并在 src) 中引用：
.container {
height: 500px;
width: 400px;
background-color: lightblue;
position: relative;
}
.favourite-icon {
position: absolute;
top: 16px;
right: 16px;
}
.favourite-icon:hover {
fill: red;
}
<div class="container">
<img src='../icon.svg' class="favourite-icon" role="button" />
</div>
谁能给点建议吗？
将 SVG 视为文档。当您将 HTML 文件包含在
中时，您无法编辑该框架中的 CSS。当您将其作为img而不是 SVG src 代码包含时，它会直接从 src 文档中提取该图像。但是，CSS
过滤器a> 允许我们直接在浏览器中应用一大堆很酷的 Photoshop 式效果。img { max-width: 100%; } img:hover { filter: invert(0.5) sepia(1) hue-rotate(200deg) saturate(4) brightness(1); }
