UIX Concepts
UI eXtension does its magic by patching various functions of HTML elements used by Home Assistant Frontend to inject a UIX styling node, <uix-node> where styles are injected into the DOM. To get the most out of UIX you can either use UIX Guides to follow what others have created, or work it out yourself.
