What Is CSS Wave Generator?

The CSS Wave Generator creates SVG-based wave section dividers for smooth, organic transitions between page sections. Waves are one of the most popular section divider styles in modern web design, replacing hard horizontal lines with flowing curves. This tool generates SVG path elements using bezier curves that create natural wave shapes. You can control the number of waves, overall height, wave color, background color, opacity, and vertical flip direction. The preview shows the wave positioned between two colored sections so you can see exactly how it transitions between content areas. The generated code includes both the SVG markup and the CSS needed to position and style the wave divider.

Why Use CSS Wave Generator?

  • Adjustable wave count, height, and color for full customization
  • Flip toggle for top or bottom section dividers
  • Preview between colored sections for realistic visualization
  • Generated code includes both SVG and positioning CSS

Common Use Cases

Section Dividers

Create smooth transitions between differently colored page sections.

Footer Transitions

Add wave dividers above footer sections for visual flow.

Hero Section Bottoms

Transition from hero sections to content with wave shapes.

Feature Section Breaks

Separate feature sections with organic wave dividers.

Technical Guide

SVG waves use the path element with cubic bezier curve (C) commands to create smooth, flowing shapes. The SVG viewBox is set to "0 0 100 100" with preserveAspectRatio="none" to stretch the wave across the full container width while maintaining the specified height. The wave shape is generated by calculating bezier control points along the horizontal axis, alternating the vertical position to create peaks and valleys. The number of waves controls how many complete oscillations appear. The height controls the amplitude of the waves. For the transition effect, the path closes at the bottom (or top when flipped) to create a filled shape. CSS positioning (width: 100%, display: block) ensures the SVG spans the full container width. The transform: scaleY(-1) can flip the wave vertically.

Tips & Best Practices

  • 1
    Use 2-4 waves for elegant, clean dividers
  • 2
    Match the wave color to the section below so the divider blends naturally
  • 3
    Use opacity below 100% for layered wave effects
  • 4
    Combine multiple waves at different opacities for depth

Frequently Asked Questions

Q Are SVG waves responsive?
Yes, with preserveAspectRatio="none" and width: 100%, the wave stretches to fit any container width.
Q Can I layer multiple waves?
Yes, stack multiple SVG waves with different colors and opacities for a layered ocean effect.
Q How do I flip the wave?
Toggle the flip checkbox, or use transform: scaleY(-1) in CSS to invert the wave direction.
Q Can I animate the wave?
Yes, use CSS animations to animate the SVG path or translate the wave horizontally for a moving water effect.
Q What height should I use?
80-120px works well for subtle dividers. Use 150-200px for more dramatic wave transitions.
