How to Build a CSS Gradient

A CSS gradient is a smooth blend between two or more colors rendered as an image you can use for a background. The two most common types are linear and radial. A linear gradient runs its colors along a straight line set by an angle, while a radial gradient spreads its colors outward from a center point in rings.

The choice shapes the mood of a design. Linear gradients feel directional and are great for headers, buttons, and full-page backdrops. Radial gradients feel like a glow or spotlight and work well for focal points, badges, and soft vignettes behind content.

In a linear gradient, the angle sets the direction of the blend. In CSS, 0deg points straight up, 90deg runs left to right, and 180deg runs top to bottom. So linear-gradient(90deg, red, blue) starts red on the left and ends blue on the right. You can also use keywords like to right or to bottom right instead of degrees.

A radial gradient does not use an angle. Instead it spreads from a center outward, and you control its shape (circle or ellipse) and how far the colors reach. Understanding this difference helps you predict the result before you write a single line of code.

The generator lets you pick colors, set the type, and adjust direction while watching a live preview. When it looks right, you copy the code and drop it straight into your stylesheet.

Keep contrast in mind. If text sits on top of a gradient, make sure the darkest and lightest regions still leave the words readable, or overlay a semi-transparent layer. Subtle, closely related colors usually look more professional than clashing opposites.

Gradients render entirely in the browser, so they add no image weight and scale crisply at any size. Save the generated code as a reusable snippet, and remember you can layer multiple gradients or combine them with solid colors for richer effects.
