Calculates the gradient along X, Y, XY, or a given dimension. Notes The Gradient function works on a single band input. Use the Extract Bands function to specify the band. If the input is multiband, the first band will be used. For multidimensional input that contains multiple variables,...
The linear-gradient() function allows you to create a linear gradient using CSS.CSS gradients allow you to apply multiple background colors to an element that blend from one color to the next. Like this: div { background: linear-gradient(to right, purple, yellow); color: white; padding:...

The CSS conic-gradient() function sets a conic gradient as the background image.A conic gradient is a gradient with color transitions rotated around a center point (like pie charts and color wheels).To create a conic gradient you must define at least two color stops....
The function conic-gradient() can have following values as arguments:1. <angle>: Value specifies the gradient rotation in clockwise direction. Takes the value as an angle and preceded by the keyword from.2. <position>:Determines the center of the gradient. Uses the same length, order, and ...
