Gradient Backgrounds


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 Linear Gradients

To create a linear gradient you must define at least two color stops. Color stops are the colors you want to render smooth transitions among. You can also set a starting point and a direction (or an angle) along with the gradient effect.

Syntax

background-image: linear-gradient(direction, color-stop1, color-stop2, ...);

Direction - Top to Bottom (this is default)

The following example shows a linear gradient that starts at the top. It starts red, transitioning to yellow:

top to bottom (default)

Direction - Left to Right

The following example shows a linear gradient that starts from the left. It starts red, transitioning to yellow:

left to right

Example

#grad {
  background-image: linear-gradient(to right, red , yellow);
}

Direction - Diagonal

You can make a gradient diagonally by specifying both the horizontal and vertical starting positions.

The following example shows a linear gradient that starts at top left (and goes to bottom right). It starts red, transitioning to yellow:

top left to bottom right

Example

#grad {
  background-image: linear-gradient(to bottom right, red, yellow);
}

Using Angles

If you want more control over the direction of the gradient, you can define an angle, instead of the predefined directions (to bottom, to top, to right, to left, to bottom right, etc.). A value of 0deg is equivalent to "to top". A value of 90deg is equivalent to "to right". A value of 180deg is equivalent to "to bottom".

Syntax

background-image: linear-gradient(angle, color-stop1, color-stop2);

The following example shows how to use angles on linear gradients:

180deg

Example

#grad {
  background-image: linear-gradient(180deg, red, yellow);
}

Using Multiple Color Stops

The following example shows a linear gradient (from top to bottom) with multiple color stops:

Example

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

The following example shows how to create a linear gradient (from left to right) with the color of the rainbow and some text:

Rainbow Background

Example

#grad {
  background-image: linear-gradient(to right, red,orange,yellow,green,blue,indigo,violet);
}

Using Transparency

CSS gradients also support transparency, which can be used to create fading effects.

To add transparency, we use the rgba() function to define the color stops. The last parameter in the rgba() function can be a value from 0 to 1, and it defines the transparency of the color: 0 indicates full transparency, 1 indicates full color (no transparency).

The following example shows a linear gradient that starts from the left. It starts fully transparent, transitioning to full color red:

Example

#grad {
  background-image: linear-gradient(to right, rgba(255,0,0,0), rgba(255,0,0,1));
}

Repeating a linear-gradient

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

Example

A repeating linear gradient:

#grad {
  background-image: repeating-linear-gradient(red, yellow 10%, green 20%);
}

Example

This linear gradient starts at the top. It starts red, transitioning to yellow, then to blue:

#grad {
  background-image: linear-gradient(red, yellow, blue);
}

Definition and Usage

The linear-gradient() function sets a linear gradient as the background image.

To create a linear gradient you must define at least two color stops. Color stops are the colors you want to render smooth transitions among. You can also set a starting point and a direction (or an angle) along with the gradient effect.

Browser Support

The numbers in the table specify the first browser version that fully supports the function.

Numbers followed by -webkit-, -moz-, or -o- specify the first version that worked with a prefix.

CSS Syntax

background-image: linear-gradient(direction, color-stop1, color-stop2, ...);

ValueDescription
direction Defines a starting point and a direction (or an angle) along with the gradient effect.
color-stop1, color-stop2,... Color stops are the colors you want to render smooth transitions among. This value consists of a color value, followed by an optional stop position (a percentage between 0% and 100% or a length along the gradient axis).
