CSS — Gradients

Gradients are smooth transitions between two or more colors. They are often used for backgrounds, buttons, and headers to create a modern look. CSS supports linear gradients (colors blend in a straight line) and radial gradients (colors spread out from the center). Gradients make designs visually appealing without using images, which helps websites load faster. They are easy to customize by adjusting direction, colors, and blending.
