What Is the CSS Divider Generator?

Create decorative section dividers: waves, diagonals, triangles, curves, zigzags, arrows and tilts. Get an inline SVG plus the CSS that sizes it, for seamless section transitions.

Why Use This Tool?

Flat, hard-edged sections make a page feel blocky. Shaped dividers create visual flow between content areas. This tool generates eight divider shapes as inline SVG, with the CSS to size and flip them.

How to Use This CSS Divider Generator

  1. Choose a divider style — Pick one of eight shapes: Wave, Wave Alt, Diagonal, Triangle, Curve, Zigzag, Arrow or Tilt.
  2. Set the colors — Pick the top and bottom section colors that the divider will separate. The divider shape blends these visually.
  3. Adjust height and width — Set the divider's height in pixels; it always spans the full width of its container.
  4. Flip and rotate — Mirror the divider horizontally or vertically to control which direction the shape flows.
  5. Copy the code — Grab the complete HTML and CSS — the divider is generated as an inline SVG for crisp rendering at any size.

How each shape uses its height, measured

Every shape is drawn in a 960 × 160 box and stretched to your page width and the Height you set (preserveAspectRatio="none"). The shapes do not all use that box the same way, which is why the same Height looks very different from shape to shape. Worked out from each shape's path:

ShapeEmpty space at the topHeight of the edge itselfAcross the width
Wave28%23%2 waves
Wave Alt48%23%3 waves
Curve50%50%one arch
Zigzag50%50%6 teeth
Arrow50%50%one point
Triangle0%100%one peak
Diagonal0%100%one slope
Tilt0%75%one slope

So at a Height of 80 px the Wave's crests and troughs are only about 18 px apart, with 23 px of the section above showing over it and 39 px of solid colour below; a Triangle at the same Height uses all 80 px. To get a wave of a given depth, set the Height to about four times that depth. Because the box stretches only horizontally, the number of waves never changes with screen width: the two waves of Wave are 195 px long each on a 390 px phone and 960 px long on a 1920 px desktop, so waves look tighter on mobile and gentler on wide screens.

No gap below the divider. A common problem with SVG dividers is a hairline of the background showing between the divider and the next section at some zoom levels. We placed the copied HTML and CSS between a white section and a section filled with the divider colour and checked the pixels along the joint in Chromium on October 12, 2026: across Wave, Diagonal and Curve, widths of 390 and 1366 px, pixel ratios of 1, 1.25, 1.5 and 2, and section heights that put the joint on a fractional pixel, none of the 48 combinations showed a seam. Set the divider's colour to exactly the next section's background colour for that to hold.

Frequently Asked Questions

Should I use SVG or CSS for dividers?
This tool outputs SVG, which handles curves and waves cleanly. CSS clip-path on the section itself is an alternative for straight-edged cuts like diagonals and arrows, but it is not what the generator produces; the Clip Path Maker builds those.
How do I flip a divider?
Apply transform: rotate(180deg) to flip a divider vertically, or transform: scaleX(-1) to mirror it horizontally.
Do dividers affect page performance?
Barely. Each generated divider is one short SVG path, a few hundred bytes of markup, with no image request.
Can I use dividers between any two sections?
Yes. Position the SVG divider absolutely at the bottom of one section or the top of the next. Use a negative margin or transform: translateY to overlap it with the section boundary for a seamless transition.
How do I match divider colors to my sections?
Set the divider's fill color to match the background of the section below it. If the top section is dark and the bottom is light, the divider should be the light color, creating the illusion that the bottom section's edge is shaped.
How do I create a section divider in CSS?+
The most flexible approach is using an inline SVG positioned between sections. You can also use CSS clip-path on the section element, CSS transforms with rotated pseudo-elements, or CSS border tricks. SVG gives the most control over shape and scales perfectly across viewport sizes.
Are SVG dividers responsive?+
Yes. The generated SVG is width 100% with preserveAspectRatio="none", so it stretches to any container width at the height you set in the CSS. That keeps the edges flush, but the shape's proportions change with the width; set preserveAspectRatio to xMidYMid slice (and keep overflow hidden) if you would rather crop than stretch.
Why does my wave look stretched on wide screens?+
The SVG is drawn in a 960 × 160 box and told to fill your container exactly (preserveAspectRatio="none"), so on a 1,920 px screen every curve is twice as wide as at 960 px. For a gentler look on wide screens, lower the height, or use a shape with more repeats such as Wave Alt or Zigzag.
What is a CSS section divider?+
A CSS section divider is a decorative separator between content sections — diagonal lines, curves, zigzags, or geometric patterns created with pure CSS. They add visual rhythm to long-scrolling pages without using background images.
How are CSS dividers created?+
Common techniques include CSS clip-path for angular cuts, SVG backgrounds for curves, CSS gradients for patterns, and CSS transforms for skewed sections. This tool generates the CSS for multiple divider styles.
