CSS Radial Gradients

CSS gradients let you display smooth transitions between two or more specified colors.

CSS defines three types of gradients:

• Linear Gradients (goes down/up/left/right/diagonally)
• Radial Gradients (defined by their center)
• Conic Gradients (rotated around a center point)

CSS Radial Gradients

A radial gradient is defined by its center.

To create a radial gradient you must also define at least two color stops.

background-image: radial-gradient(<shape> <size> at <position>, <start-color>, ..., <last-color>);

By default, shape is ellipse, size is farthest-corner, and position is center.

Radial Gradient: Evenly Spaced Color Stops (default)

The following example shows a radial gradient with evenly spaced color stops:

#grad {  
	background-image:  radial-gradient(red, yellow, green);  
}

Radial Gradient: Differently Spaced Color Stops

The following example shows a radial gradient with differently spaced color stops:

#grad {  
	background-image:  radial-gradient(red 5%, yellow 15%, green 60%);  
}

Set Shape

The shape parameter defines the shape. It can take the value circle or ellipse. The default value is ellipse.

The following example shows a radial gradient with the shape of a circle:

#grad {  
	background-image:  radial-gradient(circle, red, yellow, green);  
}

Use of Different Size Keywords

The size parameter defines the size of the gradient. It can take four values:

• closest-side
• farthest-side
• closest-corner
• farthest-corner

#grad1 {  
	background-image:  radial-gradient(closest-side at 60% 55%, red, yellow, black);  
}  
  
#grad2 {  
	background-image:  radial-gradient(farthest-side at 60% 55%, red, yellow, black);  
}

Repeating a radial-gradient

The repeating-radial-gradient() function is used to repeat radial gradients:

#grad {  
	background-image:  repeating-radial-gradient(red, yellow 10%, green 15%);  
}
