If you fix performace issues like stutter while normally browsing jellyfin while use JellySkin, try adding this to custom css to fix the issue:

@import url("https://cdn.jsdelivr.net/npm/jellyskin@latest/dist/addons/improvePerformance.css");

Warning : This removes the background blur from dialogs, gradient scroll in and out "bars" and animated mesh gradient from login page (replaced by linear gradient animation)

Want to use compact posters instead of normal cards, add this to your custom css:

@import url("https://cdn.jsdelivr.net/npm/jellyskin@latest/dist/addons/compactPosters.css");

Example:

Warning : Compact posters might not look as expected for some screen sizes

Brings back the horizontal section for My Media

@import url("https://cdn.jsdelivr.net/npm/jellyskin@latest/dist/addons/horizontalMyMedia.css");

If you want want to change the default jellyfin gradient accent to some other preset gradient use:

Note : Remember to put gradient css files below the main.css file import. Also this won't affect the login mesh background's colors.
