1. Linear gradient color gradient

Function:

linear-gradient () function is used to create an image that represents a linear gradient of two or more colors.

Syntax:

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

Copy after login

Value:

direction Use the angle value to specify the direction (or angle) of the gradient.
color-stop1, color-stop2,... Used to specify the starting and ending colors of the gradient.

Example:

<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>php中文网</title>
<style>
#grad1{
    height: 200px;
    background: -webkit-linear-gradient(yellow, green); /* Safari 5.1 - 6.0 */
    background: -o-linear-gradient(yellow, green)); /* Opera 11.1 - 12.0 */
    background: -moz-linear-gradient(yellow, green)); /* Firefox 3.6 - 15 */
    background: linear-gradient(yellow, green)); /* 标准的语法（必须放在最后） */
}
</style>

##2, size Define the size of the gradient, possible values:

farthest-corner (default): Specify the radius length of the radial gradient from the center of the circle to the corner farthest from the center
closest-side: Specify the radial gradient The radius length is from the center of the circle to the side closest to the center
closest-corner: Specifies the radius length of the radial gradient from the center of the circle to the corner closest to the center
farthest-side: Specify the radius length of the radial gradient from the center of the circle to the side farthest from the center of the circle

3. Position defines the position of the gradient. Possible values:

center (default): Set the ordinate value in the center of the radial gradient circle.
top: Set the top to be the ordinate value of the center of the radial gradient circle.
bottom: Set the bottom to the ordinate value of the center of the radial gradient circle.

4. start-color, ..., last-color is used to specify the starting and ending colors of the gradient.

Example:

<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>php中文网</title>
<style>
