HotbarCustomizer
by FischFGF
HotbarCustomizer lets players restyle the hotbar at the bottom of the screen, changing its colors, transparency and overall look while the game is running.
What it does
Hotbar appearance is set through an in-game settings menu, which opens with the O key at any time. Players choose from several styles and color options so the hotbar can match their own taste and the way they play. The author describes the aim as a cleaner, more modern heads-up display with a transparent overall design.
The mod is a Fabric client mod, so only the player needs it and servers can run without it. It works in single-player and in multiplayer, and a player can use it on a server that does not have it installed. YetAnotherConfigLib (YACL) is required, and Mod Menu is optional for access to the settings screen from the mod list. Files are released for 1.21.1 and 1.21.11, and the latest build, 1.2-ALPHA for 1.21.11, is in the alpha channel. The code is under the MIT License but the project is not open source.
Key features
Hotbar color changes
Colors of the hotbar can be changed, so each player can pick a palette that suits the rest of the interface.
Transparent design
The hotbar can be drawn with transparency, which keeps the overall layout lighter on screen.
In-game settings menu
Options are adjusted in a settings screen that opens with the O key, so no config file has to be edited by hand.
Multiplayer use
The changes apply to the local player's view, so joining a server works without any server-side setup.

Cleaner screen

Who it’s for: Players who want to customize the hotbar on Minecraft 1.21.1 or 1.21.11 with the Fabric loader, in single-player or on multiplayer servers.

FluxMenu is also client-side only, under the MIT License, for 1.21.11, and covers menu changes instead of the hotbar. ZerodayStyleHotbar is a client-side Fabric mod for 1.21.4 and is the only open source option here, under the GNU General Public License v3.0 only.
