Contextual Inline CSS Editor

This Contextual Inline CSS Editor is a powerful prototyping tool that allows users to click on specific UI elements and modify their styles in real-time. Unlike a generic devtools panel, this editor is context-aware: it reads a custom data-props attribute to generate only the relevant controls (color pickers for colors, dropdowns for display properties, etc.) for that specific element. It’s an excellent utility for design systems, website builders, or admin dashboards.
