Gradient Styles

NOTE

This component is supported since API version 4. Updates will be marked with a superscript to indicate their earliest API version.

Gradient styles are commonly supported and can be set in the style attribute or a .css file. Gradients enable smooth transition between two or more specified colors.

This framework supports two gradient styles: linear gradient and repeating linear gradient.

Linear Gradient/Repeating Linear Gradient

To use the gradient style, you need to specify the transition direction and transition color.

Transition Direction

The available values are as follows:

direction: gradient by direction.
angle: gradient by angle.

background: linear-gradient(direction/angle, color, color, ...);
background: repeating-linear-gradient(direction/angle, color, color, ...);

Transition Color

The color can be specified in any of the following formats: #ff0000, #ffff0000, rgb (255, 0, 0), and rgba (255, 0, 0, 1). At least two colors must be specified.

Parameters

Style	Type	Default Value	Mandatory	Description
direction	to <side-or-corner> <side-or-corner> = [left \|right] \|[top \|bottom]	to bottom (gradient from top to bottom)	No	Transition direction, for example, to left (gradient from right to left) or to bottom right (gradient from the top left to the bottom right).
angle	<deg>	180deg	No	Transition direction, which is the angle between the gradient line and the y-axis (in the clockwise direction), with the geometric center of the element being the origin of coordinates and the horizontal axis being the x-axis.
color	<color> [<length>\|<percentage>]	-	Yes	Colors among which smooth transitions are rendered.

Example

Gradient from top to bottom (default)

#gradient {
  height: 300px;
  width: 600px;
  /* Gradient starts from red at the top to green at the bottom. */
  background: linear-gradient(red, #00ff00);
}

Gradient at an angle of 45°

/* Gradient at an angle of 45°, changing from red to green */
  background: linear-gradient(45deg, rgb(255,0,0),rgb(0, 255, 0));

222

Gradient from left to right

/* Gradient from left to right, which is available in the 270 px width between the left 90 px and the left 360 px (600*0.6) */
background: linear-gradient(to right, rgb(255,0,0) 90px, rgb(0, 255, 0) 60%);

333

Repeating gradient

/* Repeating gradient from left to right, the area of which is 30 px (60 – 30) and the opacity is 0.5 */
background: repeating-linear-gradient(to right, rgba(255, 255, 0, 1) 30px,rgba(0, 0, 255, .5) 60px);
