Why Use RGBA?

RGBA (Red, Green, Blue, Alpha) is a CSS color format that extends RGB by adding an alpha channel for transparency control. Unlike opacity which affects the entire element, RGBA only affects the color itself, making it perfect for:

Transparent backgrounds without affecting text
Layered UI elements with precise opacity
Smooth color transitions and gradients
Modern glassmorphism and neumorphism effects
Accessible design with proper contrast ratios
