This is the part that confuses new users. Emby does not have a "Upload Theme" button. You must inject the CSS manually.
Step 1: Get the raw CSS.
If using Ultrachromic, go to the ultrachromic.css file on GitHub and click "Raw". Copy everything.
Step 2: Navigate to Emby Server Dashboard.
Go to http://your-server-ip:8096 > Login as Admin > Settings (Gear icon top right) > Advanced > General.
Step 3: Find the "Custom CSS" box. Scroll down to the "Custom CSS" text area. It is very small, but it works.
Step 4: Paste and Save. Paste your CSS code. Click Save. Restart your Emby Server (via OS or the "Restart" button in Dashboard).
Pro Tip: Emby caches CSS aggressively. After applying a new theme, perform a Hard Refresh in your browser (Ctrl + Shift + R or Cmd + Shift + R). For apps (FireTV, Roku), you may need to close/reopen the app or wait 10 minutes. emby css themes better

Unlike Plex, Emby doesn't have an official marketplace. The community hangs out on GitHub and Reddit (r/emby). Here are the three current gold standards for "better" Emby CSS.
| Do | Don't |
|----|-------|
| Use class names that persist across updates | Target random numeric IDs (#ctl00_...) |
| Group related rules with comments | Override every default style |
| Test in incognito mode (no cache) | Forget to backup your CSS |
| Use prefers-color-scheme for dark/light | Hardcode hex codes without variables |
If CSS feels too fragile, there is another way to make Emby "better" without breaking: Plugins. Custom CSS transforms Emby from utilitarian to visually
Emby defines CSS variables you can override. Add these at the top of your custom CSS:
:root
--theme-primary-color: #e50914; /* Netflix red */
--theme-background-color: #141414; /* Dark gray */
--theme-text-color: #ffffff;
--theme-accent-color: #b81b24;
Experiment with variable names by inspecting the page – not all are documented.
