In HTML, you can use the radial-gradient function to set a radial gradient. You only need to add "background:radial-gradient (starting position, shape, size, color, color, color) to the background attribute of the element. "That's it.
The operating environment of this tutorial: Windows 7 system, CSS3&&HTML5 version, Dell G3 computer.
Radial gradient: the transition from one point to the surrounding colors.
The radial gradient is as shown in the figure:
# Syntax: (must add browser prefix)
background: radial-gradient(center, shape, size, start-color, ..., last-color);
center: the starting point of the gradient Position, which can be a percentage. The default is the center of the graphic.
shape: The shape of the gradient, ellipse represents an ellipse, and circle represents a circle. The default is ellipse. If the element shape is a square element, ellipse and circle will be displayed the same.
size: Regarding the size of the radial gradient:
closest-side closest side
farthest-side farthest side
closest-corner closest corner
farthest-corner Farthest corner
The implementation code is as follows:
p{ width:500px; height:300px; margin:40px auto; background:-webkit-radial-gradient(center,closest-corner,red,yellow,green); }
Extended information:
Linear gradient: from one direction to Color change from one direction to another
Standard mode syntax (without adding browser prefix):
background:linear-gradient(direction,color-stop1,color-stop2)
Note: The default value of direction is to bottom, that is, from top to bottom
stop: The distribution position of the color, the default is uniform distribution (even distribution)
Syntax of compatibility mode (add browser prefix):
background:-webkit-linear-gradient(direction,color-stop1,color-stop2)
Description: The direction value cannot be added to, this value indicates that the color starts to gradient from this direction, contrary to the above
stop: the distribution position of the color, the default is uniform distribution (average distribution)
Gradient direction: the previous implementation of up and down or left and right Gradient, next we will introduce the diagonal gradient
1. to left \ to right \ to top (gradient up and down or left and right)
2. to left top \ to right bottom (diagonal Line gradient)
3. Changes in gradient line angle
For example: Standard mode: 40deg 40 degrees
Compatible mode: 90 - 40deg
Linear gradient : Color distribution (color area size):
linear-gradient (direction, color 1 20%, color 2 30%, color 3)
to 20%, this position is still color 1 After 20%, start the gradient to color 2
The code is as follows:
div{ width:500px; height:300px; margin:100px auto; background-image: -webkit-linear-gradient(left, red, yellow); }
