css3渐变样式怎么用

CSS3 background-image颜色渐变的实现代码

linear-gradient 是CSS3中一个重要的属性,初看觉得很简单,但是别看它简单,它能实现很多复杂的图形。

css3渐变样式怎么用(CSS3 background-image颜色渐变的实现代码)

代码还是比较简单的: linear-gradient(65deg,#2b7ce7,#2b7ce7 50%,transparent 0,transparent),linear-gradient(115deg,#2b7ce7,#2b7ce7 50%,transparent 0,transparent)

但是理解起来还是需要一定基础的。

线性渐变 linear-gradient

基本用法

  • background-image: linear-gradient(red, yellow, blue, green); 
    background-image: linear-gradient(rgba(255, 0, 0, .2), yellow, blue, green);
    
  • 控制颜色渐变的方向(right, left, top, bottom)

  • /*
        控制颜色渐变的方向
        to right -- 从左向右
        to top -- 从下到上
        to left -- 从右到左
        to bottom --- 从上到下(默认值)
    */
    background-image: linear-gradient(to right, red, yellow, blue, green);
    background-image: linear-gradient(to top, red, yellow, blue, green);
    background-image: linear-gradient(to left, red, yellow, blue, green);
    background-image: linear-gradient(to bottom, red, yellow, blue, green);
    
  • 控制颜色渐变的方向(deg)

  • /*0deg = to top -- 从下到上*/
    background-image: linear-gradient(0deg, red, yellow, blue, green);
    /*基于0度顺时针旋转45deg*/
    background-image: linear-gradient(45deg, red, yellow, blue, green);
    /*基于0度逆时针旋转45deg*/
    background-image: linear-gradient(-45deg, red, yellow, blue, green);
    
  • 控制颜色渐变的方向(to)

  • /*设置过渡颜色的起始位置*/
    /*从过渡起始位置50px开始让红色和黄色之间产生颜色渐变效果*/
    background-image: linear-gradient(to right, red 50px, yellow, blue, green);
    background-image: linear-gradient(to right, red 50px, yellow 50px, blue, green);
    background-image: linear-gradient(to right, red 50px, yellow 50px, yellow 100px, blue, green);
    
  • 重复线性渐变:repeating-linear-gradient

  • background-image: linear-gradient(to right
    , red 0
    , red 50px
    , yellow 50px
    , yellow 100px
    , red 100px
    , red 150px
    , yellow 150px
    , yellow 200px);
    /**与上面重复写渐变有相同的效果*/
    background-image: repeating-linear-gradient(
            to right
            , red 0
            , red 50px
            , yellow 50px
            , yellow 100px
    );
