<p>Three ways of showing an SVG. Do any of these show up in Windows High Contrast Mode in IE11/Edge/others? The SVG contains its own <code>style</code> block, and instead of an explicit color value it defines <code>stroke: currentColor</code> which inherits it from the current context's foreground color. This colour is automatically changed when switching into Windows High Contrast Mode, meaning that this SVG will adapt correctly to whatever color/contrast mode (including custom modes) the user has set. In addition, the icon is set to <code>opacity: 0.5</code>, but is changed to <code>opacity: 1</code> if <code>-ms-high-contrast: active</code>.</p>
<p>Note that in Firefox, you need to hard refresh (SHIFT+refresh) after changing into/out of WHCM, as the <code>currentColor</code> seems to be cached somehow persistently even when refreshing. Also, <code>opacity</code> doesn't seem to apply to SVG-based CSS backgrounds.</p>
