CustomButton
by Mix_Devs
CustomButton is a client-side Fabric utility that lets players restyle the in-game interface through a configuration screen opened from the game menu.
What it does
The configuration screen covers the main interface elements: background, text colors, buttons, checkboxes, sliders, hotbars and item names. Hue, saturation and value can be picked with an HSV color picker, and opacity, corner radius and slider handle size or text offset can be tuned for each element. Changes apply in real time while the screen stays open, so a player can compare settings without restarting.
The mod also includes a pixel-based crosshair editor where size and color are set, along with hotbar options for background and active slot styling, and item name settings for fade time and vertical offset. Because it runs only on the client, a player can use it in single-player or on any server without the server needing anything installed. CustomButton is published for Fabric across nine release versions, 1.16.5 – 26.2, and its latest file, 0.99-beta for 26.2, is on the beta channel. The code is not open source; the mod is released under All rights reserved, and snapshot builds are also published.
Key features
HSV color picker
Interface colors are chosen with an HSV picker, which allows hue to be adjusted independently of brightness and saturation.
Element transparency and corners
Opacity of backgrounds and active slots can be set, and corner radius can be changed from sharp to rounded on buttons, checkboxes, sliders and hotbars.
Crosshair editor
A pixel-based editor lets players design a custom crosshair, adjusting its size and color.
Hotbar and item names
Hotbar background, active slot styling, and the fade time and vertical offset of item name rendering can all be configured.
