How to use

  1. 1.Set an angle from 0 through 360 degrees.

About CSS Gradient Generator

CSS Gradient Generator creates a precise three-color linear gradient without requiring repeated edits in browser developer tools. Select the angle, choose three hexadecimal colors, and position each color stop from zero through one hundred percent. The preview uses the exact linear-gradient value returned in the CSS declaration, so the displayed result and copied code share one source of truth. The tool keeps all three stops explicit, making the transition structure easy to audit and adjust after the declaration moves into a stylesheet.

A CSS linear gradient is an image generated by the browser. Its first argument defines the direction of the gradient line, and the remaining arguments define colors at positions along that line. Angles use CSS degrees. Zero degrees points upward, ninety degrees points right, one hundred eighty points downward, and two hundred seventy points left. A full three hundred sixty degrees is accepted as the boundary equivalent of zero. Intermediate values create diagonals, and the apparent diagonal depends on the dimensions of the gradient box.

Color stops determine where each selected color is anchored. This generator uses percentage positions and requires them to be in ascending order. Equal adjacent stops are allowed and create a hard transition. Descending stops are rejected instead of relying on the CSS fix-up algorithm, because an explicit error is easier to understand when designing interactively. Percentages remain within zero and one hundred, covering the visible gradient line. CSS can represent stops outside this range, but that advanced behavior is intentionally outside the focused controls.

Every color is normalized as a six-digit hexadecimal value. Native color inputs make selection predictable, and logic validation prevents incomplete or ambiguous strings from entering the declaration. The tool does not calculate contrast or interpolate in a custom color space. Browser color interpolation behavior and display characteristics can affect the perceived midpoint. If brand accuracy or perceptual uniformity is critical, test the output with the exact browser support and color requirements of the project.

Gradients can replace decorative raster images and scale cleanly, but they are not free of design risks. Text placed over a gradient may pass contrast at one point and fail at another. Test the entire text area, not a single sampled color. Strong multi-color backgrounds can distract from controls and reduce hierarchy. Consider a subtle two-color variant, an overlay, or a solid fallback. Avoid conveying status solely through color, and verify themes, forced-color modes, printing, and screenshots.

The declaration uses the background shorthand for convenient copying. If an existing component also needs background color, image layers, position, or size, integrate the gradient carefully or switch to background-image so the shorthand does not reset other background subproperties. Multiple gradients can be layered with commas, but this generator produces one linear layer. It intentionally omits radial, conic, repeating, transparency-alpha, and interpolation-space controls to keep results readable and testable.

Everything runs locally in the current tab. Values are not uploaded or saved, no account is required, and no dependency is added. Start with stops at 0, 50, and 100 percent, adjust the angle for the component's aspect ratio, then move the middle stop to control where the blend changes most strongly. Copy the CSS only after testing real content, responsive sizes, contrast across the full surface, and fallbacks required by your supported environments.

Methodology & sources

Validates a 0–360 degree angle, three six-digit hex colors, and ordered 0–100 percent stops, then serializes a standard three-stop linear-gradient and uses that exact value for preview and copy.

Frequently asked questions

Why must stops be in ascending order?
Ordered controls make the design intent explicit. Equal stops can create a hard edge, while descending stops are rejected instead of being silently fixed up.
Why does the same angle look different on another box?
The gradient line is resolved against the gradient box, so changing the element aspect ratio changes the apparent diagonal.
Does this check text contrast?
No. Contrast can vary across the surface, so test every area where text or controls appear.
