what is jellyskin fr?

JellySkin is a custom visual theme for Jellyfin, a popular open-source media server application. Jellyfin lets you host your own movies, TV shows, and music and stream them to your devices through a web browser. By default, the Jellyfin web interface looks fairly utilitarian, but this project applies a vibrant, minimal redesign with custom icons and a variety of animations. The goal is to make your personal media library feel more like a polished commercial streaming app and less like a file manager. Applying the theme is straightforward. Jellyfin has a built-in setting where administrators can paste custom CSS, styling instructions that change how a web page looks without altering its underlying content. You copy one provided line of text into the "Custom CSS" box in your server dashboard, save, and the new look applies instantly to everyone using that server. There are no installations or complex configuration files to manage, removing the theme is as simple as deleting that line and saving again. Beyond the base theme, the project offers several optional add-ons you can enable the same way. One add-on switches the media browsing cards to a more compact poster style, which is useful if you want to fit more titles on the screen. Another prioritizes performance by toning down some of the heavier visual effects, which helps if the animations cause stuttering on slower devices. You can also swap the default color scheme for presets like Mauve, NightSky, or Sea, or define your own custom gradient colors. This project is aimed at anyone running a Jellyfin server who wants to spruce up their interface without writing code. The documentation also includes helpful fixes for common issues, such as configuring the Firefox browser to properly display the theme's blurred backgrounds, or installing a metadata plugin so studio logos appear next to your movie titles.
