.card {
background-image: radial-gradient(circle at center, #fff 0%, #4b6cb7 65%, transparent 100%);
}This creates a color transition that radiates outward from the center. A radial gradient is an image value, not a color, so it does not belong in background-color.
Radial gradient syntax
The general form is radial-gradient([<shape> || <size>] [at <position>], <color-stop-list>). Set the optional shape, size, and position before the comma; put the color stops after it.
.panel {
background-image: radial-gradient(ellipse closest-side at 30% 40%, white, royalblue 70%, transparent);
}The core syntax is defined by the W3C CSS Images Module Level 3 specification. If you omit the controls, the defaults are an ellipse, farthest-corner size, and centered position.

Choose the shape, size, and position
Shape: circle or ellipse
circle makes the gradient round; ellipse makes it an axis-aligned oval. The default is ellipse. For a circle with a specific radius, use a length after the shape, such as circle 12rem.
Size: extent keywords or lengths
Extent keywords determine where the gradient’s ending shape reaches relative to the element:

You can also use explicit lengths when you want a defined radius or radii instead of an extent keyword. The best choice depends on whether the effect should adapt to the element’s dimensions or keep a set size.
Position: move the gradient center
Use at followed by a CSS position. For example, at 25% 30% places the center at a percentage of the element, while at top right places it at that corner. Without an authored position, the center is the element’s center.

Control the transition with color stops
Each color stop has a color and may have one or two positions. Positions are measured along a virtual ray from the gradient center toward the ending shape: 0% is at the center and 100% is where that ray reaches the ending shape. If you leave positions out, CSS distributes the unspecified stops according to its gradient rules.
Soft spotlight
.spotlight {
background: radial-gradient(ellipse at 30% 20%, #fff8 0%, #77aaff66 35%, transparent 70%);
}The translucent colors and their positions make the transition fade outward. Adjust the center and stops to place the light and change how far it spreads.

Hard-edged rings or bands
Adjacent stops at the same position create a sharp boundary rather than a gradual blend:
.badge {
background: radial-gradient(circle, #ffcf33 0 58%, #d85624 58% 60%, transparent 60%);
}Here, the repeated positions make the transition from yellow to orange and then transparent sharply bounded.

Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Element size and repeating gradients
A gradient has no intrinsic dimensions or preferred aspect ratio. Its concrete size matches the element receiving it, so the element’s size and shape affect how the gradient appears. If you want rings to repeat outward across the element, use repeating-radial-gradient():
.rings {
background: repeating-radial-gradient(circle, #263238 0 8px, #80cbc4 8px 16px);
}Browser support and newer syntax
MDN labels radial-gradient() Baseline Widely available and reports browser availability since July 2015. MDN also notes that support can vary for some parts of the syntax. The basic function is established; if your design relies on newer color-interpolation syntax, check compatibility for that specific feature in the MDN radial-gradient() reference.
Common problems and fixes
- The gradient does not appear: Apply it to
backgroundorbackground-image, notbackground-color; the function produces an image value. - The gradient looks oval rather than round: Specify
circle. The default shape isellipse. - The fade ends in an unexpected place: Review the size keyword and stop positions. Size controls the ending shape, while stops control color transitions along rays toward that shape.
- The effect is centered in the wrong place: Add
atand a position before the comma, such asat 30% 20%. - A newer color treatment differs across browsers: Check support for that color-interpolation syntax specifically; broad support for the basic function does not establish support for every newer option.
- Rings blend instead of having crisp edges: Put adjacent color stops at the same position to define a hard boundary.
