It has modified the colors of:

• Backgrounds
• Fonts
• Emojis
• Photos!!!

Issues I’ve tried:

1. Added inside ...
   • eBay strips the tag however retains the tag
2. Added :root, * { color-scheme: solely gentle !necessary; } inside my .css file
3. Modified my CSS guidelines to !necessary
4. Set html, physique { background-color: #ffffff !necessary; }
5. Set html, physique { background-color: #000000 !necessary; background-image: linear-gradient(#ffffff, #ffffff) !necessary; }
6. I observed that eBay wraps my whole description in a
   so I attempted resetting all properties with .x-item-description-child { all: preliminary }

7. Modified the hyperlink to my .css file to make use of ?v=12345, to drive a cache-bust

These adjustments repair Safari however have zero impact on the eBay app.

1. Which browser is the eBay app utilizing underneath the hood?

   • Are they utilizing the wkwebview management?
   • Can eBay use this management be used to inject pressured types? It appears to be attainable
   • If that's the case, how can these be overridden by the web page being displayed by the management - I.E. me?
2. How can I drive the eBay app to respect the colors I've chosen?
   • eBay prevents using JavaScript
3. Alternatively, how can I set my very own darkish theme within the CSS?
   • The same old methodology of @media (prefers-color-scheme: darkish) { .someElement { background: black } } seems to don't have any impact
4. Does this behaviour additionally have an effect on their Android app?
