What is a gradient?
Gradients are CSS elements of the
image data type that show a transition between two or more colors. These transitions are shown as either linear or radial. Because they are of the
image data type, gradients can be used anywhere an image might be. The most popular use for gradients would be in a background element.
To put it more relevantly, gradients are part of an extremely popular design trend that has been gaining popularity over the last several years. It seems that they have always been around in the background (no pun intended); although, some sources claim that the trend is “coming back”. Of course, it’s hard for something to come back if it never left, but we’ll chalk that up to semantics.
