Gradient Styles
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 following four colors are supported: #ff0000, #ffff0000, rgb (255, 0, 0) and rgba (255, 0, 0, 1). At least two colors must be specified.
- Name
Name | 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 right (gradient from left to right) or to bottom right (from the top left to the bottom right). |
angle | <deg> | 180deg | No | Transition direction. 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));
- 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%);
- 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);
