css to achieve gradient

CSS is a commonly used web page style design language that can achieve various beautiful effects. Among them, the gradient effect is a technique commonly used by many web designers and can be achieved through CSS. This article will introduce how to use CSS to achieve gradient effects, including linear gradients and radial gradients.

1. Linear gradient

Linear gradient refers to the process of gradually changing colors in one direction. We can achieve this effect through the linear gradient property of CSS.

The specific implementation method is as follows:

1. Create an HTML element and set its CSS style

< ;/div>

.box {

width: 300px;
height: 200px;
background: linear-gradient(to right, #03a9f4, #f44336);

}

2. In the CSS code, use the "linear-gradient" attribute to define a linear gradient

Linear-gradient has two parameters. The first parameter is the direction, which supports to left, to right, to bottom, to top, to bottom left and other specified directions. The second argument is an array of color values, separated by commas. The color values ​​in this array represent the gradient of the color from the starting point to the end point of the gradient.

For example, the following code represents a linear gradient from left to right. The starting point of the gradient is #03a9f4 and the end point is #f44336:

background: linear-gradient(to right, #03a9f4, # f44336);

We can also set multiple color values ​​to make the color gradient smoother:

background: linear-gradient(to right, #03a9f4, #2196f3, #9c27b0, #f44336 );

In this way, there will be four different color transitions from left to right.

2. Radial Gradient

Radial gradient refers to the process of color gradient starting from a center point and gradually moving around. We can also achieve this effect through CSS.

The specific implementation method is as follows:

1. Create an HTML element and set its CSS style

< ;/div>

.box {

width: 300px;
height: 200px;
background: radial-gradient(circle at center, #03a9f4, #f44336);

}

2. In the CSS code, use the "radial-gradient" attribute to define a radial gradient

radial-gradient has three parameters. The first parameter specifies the gradient type, supporting circle (circle) and ellipse (ellipse). The second parameter specifies the position of the gradient center, using the syntax "X-axis position Y-axis position". For example, "center center" means starting the gradient at the center of the element.

The third parameter specifies an array of gradient color values, also separated by commas.

For example, the following code represents a radial gradient starting from the center. The starting point of the gradient is #03a9f4 and the end point is #f44336:

background: radial-gradient(circle at center, #03a9f4, #f44336);

We can also set multiple color values ​​to make the gradient smoother:

background: radial-gradient(circle at center, #03a9f4, #2196f3, #9c27b0, # f44336);

In this way, during the process of gradient starting from the center to the surroundings, the color will gradually change from the first value to the last value, going through the gradient process in the middle.

3. Other gradients

CSS also supports other types of gradients, such as repeating gradients, irregular gradients, etc. The implementation methods of these gradient types are also similar, which can be achieved by setting the style attributes.

For example, the following code represents a repeating linear gradient:

background: repeating-linear-gradient(to right, #03a9f4, #2196f3-20px, #f44336 40px);

In this code, the starting point of the color gradient is #03a9f4 and the end point is #f44336. The color change will be repeated until the entire element is filled. Among them, "#2196f3-20px" means that this color value will be reduced by 20 pixels in the x-axis direction, thus forming a staggered effect.

4. Summary

The gradient effect of CSS can make the design of the web page more vivid and eye-catching. This article explains how to implement linear and radial gradients, as well as code examples for several other gradient types. hope that it can help us.
