Generate CSS wave dividers between sections with customizable wave height, color, animation, and flip orientation.
A CSS wave divider is a decorative element placed between website sections that creates a smooth, wavy transition instead of a straight line. Unlike flat dividers, wave dividers add visual rhythm and organic flow to page layouts.
Wave dividers are typically created using inline SVG embedded as CSS background-image data URIs on pseudo-elements. This approach keeps the CSS self-contained without requiring external files. Waves can be animated to create a gentle flowing effect.
