In css, there is the radial-gradient() function to create radial gradients for elements. The linear-gradient() function creates a linear gradient style for an element.

1. The radial-gradient() function creates an "image" with a radial gradient.

The radial gradient is defined by the center point. In order to create a radial gradient two stop colors must be set.

The syntax is as follows:

background: radial-gradient(shape size at position, start-color, ..., last-color);

2. The linear-gradient() function is used to create a picture that represents a linear gradient of two or more colors.

To create a linear gradient, you need to specify two colors. You can also achieve gradient effects in different directions (specified as an angle). If the direction is not specified, the gradient will default from top to bottom.

The syntax is as follows:

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