How to set gradient in css-CSS Tutorial-php.cn

Method: 1. Use linear-gradient() to implement linear gradient, the syntax is "linear-gradient (angle, starting and ending color list)"; 2. Use radial-gradient() to implement radial gradient, the syntax is "radial -gradient (size position, starting and ending colors)".

linear-gradient() function--linear gradient

linear-gradient() function is used to create an "image" of a linear gradient .

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.

Syntax:

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

Parameters:

Value	Description
direction	Specify the direction (or angle) of the gradient using an angle value.
color-stop1, color-stop2,...	is used to specify the starting and ending colors of the gradient.

radial-gradient() function--radial gradient

radial-gradient() function is created with radial gradient" image".

The radial gradient is defined by the center point. Example:

How to set gradient in css

To create a radial gradient you must set two stop colors.

css Radial color gradients (Radial Gradients) are different from linear gradients (linear gradients). It does not gradient along one direction, but takes a point as the center and radiates gradients around 360 degrees.

Syntax:

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

Copy after login

Parameter value:

Value	Description
shape	Determine the type of circle: ellipse (default): Specifies the radial gradient of the ellipse. circle: Specify the radial gradient of the circle
size	Define the size of the gradient, possible values: farthest-corner (default): specifies the radius length of the radial gradient from the center of the circle to the corner farthest from the center closest-side: specifies the radius length of the radial gradient from the center of the circle to the corner farthest from the center The side closest to the center of the circle closest-corner: Specifies the radius length of the radial gradient from the center of the circle to the corner closest to the center of the circle farthest-side: Specifies the radius length of the radial gradient from the center of the circle To the edge farthest from the center of the circle
position	defines the position of the gradient. Possible values: center (default): Set the middle ordinate value of the center of the radial gradient circle. top: Set the top to 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.
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"> 
<style>
#grad1 {
    height: 150px;
    width: 200px;
    background-color: red; /* 浏览器不支持的时候显示 */
    background-image: radial-gradient(red, yellow, green); /* 标准的语法（必须放在最后） */
}

#grad2 {
    height: 150px;
    width: 200px;
    background-color: red; /* 浏览器不支持的时候显示 */
    background-image: radial-gradient(circle, red, yellow, green); /* 标准的语法（必须放在最后） */
}
</style>
</head>
<body>

<h3>径向渐变 - 形状</h3>
