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 );
以上就是本文的全部内容,希望对大家的学习有所帮助,也希望大家多多支持三水点靠木。
