Convert HEX color codes to RGBA format with alpha transparency for CSS rgba() functions, overlays, and semi-transparent UI elements. While HEX colors like #FF5733 are common in design tools, RGBA format rgba(255, 87, 51, 0.8) adds an alpha channel for transparency control. This is essential for creating overlays, modals, shadows, and any UI element that needs to be semi-transparent.
