use-pixelated-css

A React hook that transforms CSS styles into a pixelated form.

Features

• Transforms original CSS styles into pixelated versions
• Automatically updates pixelation when element size changes via ResizeObserver
• Cleans up ResizeObserver when component unmounts
• Can be used internally by UI components like Button to apply pixelated styles
