CSS3 background-image颜色渐变的实现代码
(编辑：jimmy 日期: 2024/11/2 浏览：2)
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。
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
);
