How to use css3 gradient attribute

The CSS3 gradient attribute is a new style effect added to CSS3, which can achieve color transition effects and make the web page UI more smooth and beautiful. This article will introduce the use of CSS3 gradient attributes, attribute values, and common application examples.

How to use the CSS3 gradient attribute

To use the CSS3 gradient attribute, you need to first define an element, and then set the gradient attribute in the style of the element. CSS3 gradient properties are implemented through the gradient function.

The specific usage is as follows:

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

Attribute value of CSS3 gradient attribute

* direction: gradient direction, which can be deg (angle value, 0deg It means gradient from left to right; 90deg means gradient from top to bottom), or it can be a keyword (for example, to left, means gradient from right to left).

* color-stop: color breakpoint, indicating the end point of color transition, which can be a specific color value (such as #000) or a percentage (such as 50%).

Application examples of CSS3 gradient properties

Linear gradient

Linear gradient refers to color transition on a straight line Effect. The following are some common ways to write linear gradients:

```
/* 从左到右渐变 */
background-image: linear-gradient(to right, #000, #fff);
/* 从上到下渐变 */
background-image: linear-gradient(to bottom, #000, #fff);
/* 左上到右下渐变 */
background-image: linear-gradient(to bottom right, #000, #fff);
/* 自定义方向渐变 */
background-image: linear-gradient(30deg, #000, #fff);
```

Radial Gradient

Radial gradient refers to the effect of spreading the gradient outward from a starting point. The following are some common ways of writing radial gradients:

```
/* 从内向外径向渐变 */
background-image: radial-gradient(circle, #000, #fff);
/* 自定义渐变形状 */
background-image: radial-gradient(ellipse, #000, #fff);
/* 自定义渐变形状和渐变起始点 */
background-image: radial-gradient(ellipse at right top, #000, #fff);
/* 使用百分比设置渐变范围 */
background-image: radial-gradient(ellipse at center, #000 10%, #fff 90%);
```

In addition, CSS3 gradient properties can also achieve complex gradient effects, such as two-dimensional backgrounds, changing color breakpoint positions, etc. Readers can further learn and master by consulting relevant information.

In short, the use of CSS3 gradient attributes can add more beauty and smoothness to the web UI, and help improve the user experience
