What Is a CSS Gradient Generator?
A CSS gradient generator is a visual tool that helps you create smooth color transitions using pure CSS — no image files needed. Instead of manually writing complex linear-gradient(), radial-gradient(), or conic-gradient() syntax by hand, you can drag color stops, adjust angles, and see the result in real time. Once you're happy with the gradient, copy the production-ready CSS with one click.
CSS gradients are rendered natively by the browser, making them resolution-independent, faster-loading than background images, and easy to animate with transitions or keyframes. They're one of the most powerful visual tools in modern CSS.
How to Use This CSS Gradient Generator
- Choose a gradient type — select linear, radial, or conic from the type selector. Linear is the most common for backgrounds and hero sections.
- Add and adjust color stops — click the gradient bar to add new color stops. Drag them left or right to control where each color begins and ends. Click any stop to change its color.
- Set the angle or position — for linear gradients, adjust the angle (0°–360°). For radial gradients, choose the shape (circle or ellipse) and position.
- Try a preset — start from one of the curated presets (Sunset, Ocean, Aurora, etc.) and customize from there.
- Copy the CSS — click the copy button to grab the complete
backgroundproperty, ready to paste into your stylesheet.
CSS Gradient Types Explained
Linear Gradient
Colors flow along a straight line at a specified angle. The default direction is top-to-bottom (180°). Linear gradients are the workhorse of web design — ideal for page backgrounds, card overlays, hero sections, and button hover effects. The syntax is linear-gradient(angle, color1, color2, ...).
Radial Gradient
Colors radiate outward from a center point in a circular or elliptical shape. Radial gradients are perfect for creating spotlight effects, glowing orbs, button highlights, and focal-point backgrounds. You can control the shape (circle vs. ellipse) and the center position.
Conic Gradient
Colors rotate around a center point like a color wheel. Conic gradients are newer to CSS and are great for pie charts, color wheels, loading indicators, and decorative patterns. The syntax is conic-gradient(from angle, color1, color2, ...).
Two checks before you ship a gradient
Two problems are easy to miss in a gradient and easy to measure. Both checks below were rendered in Chromium 141 on October 12, 2026 and read back pixel by pixel.
1. The grey band between distant colours
This builder writes standard CSS, and CSS blends colour stops in sRGB unless told otherwise. Between two colours on opposite sides of the colour wheel, that path runs through grey: in linear-gradient(to right, #0000FF, #FFFF00) the middle pixel is rgb(127, 127, 127), with an OKLCH chroma of 0 (no colour at all). Two fixes, measured on the same 1000 px strip:
- Add a middle stop in the builder. With
#00C8A0at 50%, chroma never drops below 0.111 anywhere along the strip. - Add
in oklchafter the direction in the copied CSS (linear-gradient(to right in oklch, …)); the midpoint becomesrgb(0, 207, 188)and chroma stays above 0.126. The builder does not add this keyword itself. MDN lists support from Chrome and Edge 111, Safari 16.2 and Firefox 127, so keep the plain version on the line above as a fallback.
Colours that sit close together on the wheel, such as most of the presets here, do not have this problem.
2. Text contrast across the whole gradient
Text has to be readable at its worst point, not its average. The table gives the lowest contrast ratio found along each preset for pure white and pure black text; WCAG 2.2 success criterion 1.4.3 asks for at least 4.5:1 for normal text and 3:1 for large text.
| Preset | White text, worst point | Black text, worst point |
|---|---|---|
| Sunset | 1.29:1 | 11.61:1 |
| Ocean | 1.39:1 | 4.69:1 |
| Aurora | 1.29:1 | 7.17:1 |
| Berry | 1.50:1 | 7.19:1 |
| Fire | 1.40:1 | 5.52:1 |
| Midnight | 12.72:1 | 1.10:1 |
| Arctic | 1.21:1 | 15.31:1 |
| Forest | 2.51:1 | 2.28:1 |
Most presets work with black text and not with white; Midnight is the reverse. Ocean passes with black by a small margin (4.69:1), and Forest fails with both, so any text on Forest needs a darker overlay or a text shadow. Check your own stops the same way with the Contrast Checker at the lightest and darkest stop.

- Before hand-tuning, the Gradient Interpolator shows the same gradient in sRGB, OKLCH, and OKLab side by side so you can pick the right interpolation mode.
- If your two-color gradient has muddy midpoints, the Gradient Stop Optimizer converts it into an optimized 5, 7, or 9-stop OKLCH-spaced version automatically.
- Stacked gradients with blend modes is a common composition trick. The Color Blend Modes tool previews the exact two-color combinations across nine blend modes.
