CSS3中如何实现渐变效果

Answer 1

要得上面的线性渐变效果，我们这样去定义CSS3样式：background-image:-moz-linear-gradient(top,#8fa1ff, #3757fa); /* Firefox */background-image:-webkit-gradient(linear, left top, left bottom, color-stop(0,#ff4f02), color-stop(1, #8f2c00)); /* Saf4+, Chrome */filter: progid:DXImageTransform.Microsoft.gradient(startColorstr='#c6ff00', endColorstr='#538300',GradientType='0');/* IE*/-moz-linear-gradient有三个参数。第一个参数表示线性渐变的方向，top是从上到下、left是从左到右，如果定义成left top，那就是从左上角到右下角。第二个和第三个参数分别是起点颜色和终点颜色。你还可以在它们之间插入更多的参数，表示多种颜色的渐变。线性渐变使用from()以及to()方法指定过渡颜色点:background:-webkit-gradient(linear, left top, left bottom,from(#96ff00), color-stop(0.5, orange), to(rgb(255, 0, 0)));线性渐变多个过渡点在同一位置：background:-webkit-gradient(linear, left top, left bottom,from(#00abeb), to(#fff), color-stop(0.5, #fff), color-stop(0.5, #66cc00));径向渐变综合效果演示：background:-moz-radial-gradient(30px30px, circle farthest-corner,#58ff00 0%, rgba(222, 255, 0, 0) 30%),-moz-radial-gradient(50px70px, circle farthest-corner,#F30 0%, rgba(255, 159, 34, 0) 60%),-moz-radial-gradient(80px10px, circle farthest-corner,#03F 0%, rgba(222, 255, 0, 0) 80%);background:-webkit-gradient(radial,105105,20,112120,50,from(#ff5f98), to(rgba(255,1,136,0)), color-stop(75%, #ff0188)),-webkit-gradient(radial,9515,15,10220,40,from(#00c9ff), to(rgba(0,201,255,0)), color-stop(80%, #00b5e2)),-webkit-gradient(radial,0150,50,0140,90,from(#f4f201), to(rgba(228, 199,0,0)), color-stop(80%, #e4c700));circle farthest-corner圆形渐变，ellipse farthest-corner椭圆渐变PS：感谢网友来到前端开发分享网学习~~ 欢迎大家扫二维码学习更多相关前端知识!!
