I was previously using the CSS from [GitHub - pyxfluff/Blackout · GitHub](https://github.com/pyxfluff/Blackout) to change the background to a deeper black (you can see examples [Blackout - A Theme For OLED Displays](https://meta.discourse.org/t/blackout-a-theme-for-oled-displays/235047) ). It was working fine, but today after I updated all the read topics on the main page have defaulted to the grey color of the underlying theme (unread remains the same). I’ve been trying dozens of changes and none of them have made a difference.

This specifically

`body, .boxed.white, .admin-detail, .admin-controls, .admin-controls .controls, .user-content,.group-details-container,`  
`div.edit-category .edit-category-title-bar, .user-main .about, .user-main .about .details .primary,`  
`.user-main .about .details, .user-stream .item, .user-stream .user-stream-item, .search-container .search-header,`  
`.search-container .search-filters .search-advanced-filters, .search-container .search-bar,`  
`.search-container .search-filters {`  
`background-color:#000!important;`  
`}`

When removed resets the entire background back to the same matching color. So obviously something here isn’t targeting the “read” backgrounds anymore, but nothing I add makes a difference.

Want all the topics in both states to still look like the bottom, not the top . Is this still possible to do? I don’t know what or how to target that and AI just keeps giving me more non-working CSS too when I try to get that to figure it out.
