CSS Gradient Generator

Compose a linear gradient visually, tune its angle and colors, and copy the exact CSS declaration.

What CSS Gradient Generator helps you do

Compose a two-color linear gradient visually, set its angle, and copy the exact CSS declaration. It removes the trial and error of writing gradient syntax by hand. The preview updates live, and the output is a single background value ready to paste.

Gradient generation runs locally in your browser; nothing is uploaded to Haivix.

How it works

Color tools work in numeric color spaces rather than pixels. RGB stores three channels from 0 to 255, hex is the same three bytes written in base 16, and HSL describes hue, saturation and lightness. These values are device-independent numbers; the same hex code can look different on an uncalibrated screen, and print uses CMYK inks that do not map one-to-one to RGB. Everything here is computed locally and copied as text. A value is only a starting point: the surrounding colors, display brightness and viewing conditions change how it reads. Modern CSS also accepts alpha, so a value may carry a fourth channel that older tools ignore.

How to use CSS Gradient Generator

  1. Pick the start and end colors.
  2. Drag the angle slider until the preview matches the design.
  3. Copy the generated background declaration.
  4. Paste it into your stylesheet and check it in context.

When to use it

  • Build a background gradient for a hero section.
  • Get the exact CSS for a gradient you designed by eye.
  • Create a reusable gradient declaration for a theme.
  • Match a designer's gradient sample in code.
  • Prototype a button or card background quickly.
  • Generate a fallback color layer for a hero image.

When not to use it

  • Do not use it for radial or conic gradients.
  • Do not expect more than two color stops.
  • Do not rely on it for color-managed print output.

Example

Two colors at a 135-degree angle produce background: linear-gradient(135deg, #2563eb, #06b6d4); ready to paste into CSS. Changing the angle rotates the direction of the blend without changing the endpoint colors. The declaration uses modern syntax, so very old browsers may need a fallback.

What you can do with CSS Gradient Generator

  • Set a start and end color.
  • Adjust the angle from 0 to 360 degrees.
  • Preview the gradient live.
  • Read the generated CSS declaration.
  • Copy the value with one button.
  • Run the generator locally in the browser.

Example: choose a value, then test it in context

Pick a base color and note its values in more than one notation, since design tools and code often expect different formats.

Test the color against the actual background and text, not against a white canvas. Contrast changes with every neighboring color.

Check the result on a second display if the color matters for a brand. Screens vary in calibration and gamut.

Keep the original value in your notes so a failed experiment can be reversed without guessing.

Copy the final value in the notation the destination expects. A hex code with a hash is not always accepted where a bare hex string is.

If the color is for print, treat the screen value as a reference only and confirm with a CMYK proof or a physical sample.

Name the value in the design system rather than scattering raw hex codes. A token makes a later adjustment a single change instead of a search across files.

What to know before you start

  • It generates linear gradients, not radial or conic ones.
  • The copied CSS is a static value and does not include vendor-specific fallbacks.
  • Only two color stops are supported.
  • It does not check text contrast or accessibility.

Common mistakes

  • Expecting three or more stops.
  • Forgetting the semicolon when pasting into CSS.
  • Assuming the angle matches a design tool's convention.
  • Using a gradient where a flat color would be more accessible.
  • Placing long text over a gradient without checking both ends.

Troubleshooting

If the preview looks flat, the two colors may be identical.

If the copied value does not apply, check that the property is background or background-image.

If the gradient direction seems rotated, design tools measure angles differently.

If contrast is poor, test the text color against both ends of the gradient.

If the gradient shows banding, the two colors are too close and the display is quantizing the blend.

If the preview is blank, the element may have no height for the gradient to fill.

Related standards and documentation

  • sRGB (IEC 61966-2-1) is the default color space for the web.
  • CSS Color Module Level 4 defines hex, rgb(), hsl() and modern color syntax.
  • WCAG 2.1 defines the contrast ratios used for accessible text.
  • ICC profiles describe a display or printer gamut and are not encoded in a hex value.
  • Hex notation uses two digits per channel, so each channel runs from 00 to FF.
Numbers, not ink
  • Check more than one notation.
  • Test against the real background.
  • Verify contrast.
  • Screens vary.
