描述
See this page, where the anchor points to an SVG. If you ensure that there's no theme in local storage for this page, then if the browser settings are used to switch between dark and light modes (I'm using Firefox), the SVG is styled appropriately to display correctly. However, if I use the theme selector on the page to select dark mode when the browser is set to light mode, the SVG does not display correctly.
The reason is that I style for light mode and use a media query to override some styles, using @media (prefers-color-scheme: dark). However, when the theme selector is used to select dark mode, then some dark-mode CSS is pulled in using the activateTheme() JS function, but from what I can tell this leaves no trace in the markup that we're now in dark mode. If there were e.g. a dark-theme class added to the <body> tag when the page is in dark mode, then I could duplicate the styling using an appropriate selector. My complete styling of the SVG is:
svg {
background-color: transparent !important;
}
line {
stroke: #000000;
fill: none;
stroke-opacity: 1;
}
polygon, rect {
fill: none;
stroke: #000000;
fill-opacity: 1;
stroke-opacity: 1;
}
polygon.filled {
fill: #ff0000;
}
polyline {
fill: none;
stroke-opacity: 1;
stroke: #000000;
}
text {
fill: #000000;
fill-opacity: 1;
stroke: none;
font-family: sans-serif;
font-style: normal;
font-weight: normal;
text-anchor: start;
}
@media (prefers-color-scheme: dark) { /* could duplicate this styling if body.dark-theme */
polygon, rect, polyline, line {
stroke: #ffffff;
}
text {
fill: #ffffff;
}
}
If there is another approach I could use to achieve the desired result (proper styling of the SVG in all cases), please let me know. Otherwise, would you consider adding dark-theme class to the body or other container tag so that I could try and achieve the desired result? Or have I missed somewhere where such a class has been added?

研究方向
首先追蹤主題選擇器和 activateTheme() 函式，了解所選主題如何套用至頁面。向相關頁面容器新增可靠的深色模式標記，然後確認 SVG 樣式可以區分由選擇器選取的深色模式、淺色模式和瀏覽器偏好設定的深色模式。
