多种CSS3渐变应用方法总结附实例
如下图所示,在网页设计中,有时候会需要用到渐变效果,渐变可以创建出类似于彩虹的视觉图案效果,在没有CSS3之前,为了显示一个渐变需要专门制作一个图片,这种不法不但不灵活还增加请求数,而CSS3可以轻松实现网页渐变效果,用于做渐变背景、渐变导航、配合CSS3动画做特效等。在CSS3中,Gradient(渐变)分为linear-gradient(线性渐变)和radial-gradient(径向渐变)。CSS颜色线性渐变的语法在各种浏览器里的实现稍微有些不同,但最后是统一标准的:
CSS颜色线性渐变的语法
background-image: linear-gradient(<point> || <angle>,]? <stop>, <stop> [, <stop>]*)
第一个参数是渐变起始点或角。第二个参数是一种颜色停止点(color stops)。至少需要两种颜色(起点和终点),你可以添加任意种颜色来增加颜色渐变的丰富程度。对颜色停止点的定义可以是一种颜色,或一种颜色加一个百分比:
/* color-stop(percentage/amount, color) */ color-stop(0.20, red)因为CSS渐变色(Gradients)技术是CSS3里比较新的技术,属于高级的CSS功能,于是每种浏览器对这种技术的实现都添加了一些自己的特色。例如以WebKIt为渲染引擎的谷歌浏览器,就对它实现了多种语法。下面的这段代码基本包括了所有自顶向下颜色渐变的所有情况:
#example1 { /* 底色 */ background-color: #063053; /* chrome 2+, safari 4+; multiple color stops */ background-image:-webkit-gradient(linear, left bottom, left top, color-stop(0.32, #063053), color-stop(0.66, #395873), color-stop(0.83, #5c7c99)); /* chrome 10+, safari 5.1+ */ background-image: -webkit-linear-gradient(#063053, #395873, #5c7c99); /* firefox; multiple color stops */ background-image: -moz-linear-gradient(top,#063053, #395873, #5c7c99); /* ie 6+ */ filter: progid:DXImageTransform.Microsoft.gradient(startColorstr='#063053', endColorstr='#395873'); /* ie8 + */ -ms-filter: "progid:DXImageTransform.Microsoft.gradient(startColorstr='#063053', endColorstr='#395873')"; /* ie10 */ background-image: -ms-linear-gradient(#063053, #395873, #5c7c99); /* opera 11.1 */ background-image: -o-linear-gradient(#063053, #395873, #5c7c99); /* 标准写法 */ background-image: linear-gradient(#063053, #395873, #5c7c99);注意,我们首先设定了一个背景色。这个颜色是在万一用户使用的浏览器不支持CSS渐变色(Gradients)技术时使用的颜色。CSS渐变色(Gradients)技术里还支持带有角度的渐变方向,而不仅仅只有直上直下或直左直右。我们可以用下面的语法实现它:
#example2 { /* fallback */ background-color:#063053; /* chrome 2+, safari 4+; multiple color stops */ background-image:-webkit-gradient(linear, left bottom, right top, color-stop(0.32, #063053), color-stop(0.66, #395873), color-stop(0.83, #5c7c99)); /* chrome 10+, safari 5.1+ */ background-image:-webkit-linear-gradient(45deg, #063053, #395873, #5c7c99); /* firefox; multiple color stops */ background-image:-moz-linear-gradient(45deg, #063053, #395873, #5c7c99); /* ie10 */ background-image: -ms-linear-gradient(45deg, #063053 0%, #395873 100%); /* opera 11.1 */ background-image: -o-linear-gradient(45deg, #063053, #395873); /* The "standard" */ background-image: linear-gradient(45deg, #063053, #395873); }我们可以做的更复杂些….一个色彩缤纷的CSS颜色渐变?下面我们来做一个彩虹:
/* example 3 - linear rainbow */ #example3 { /* fallback */ background-color:#063053; /* chrome 2+, safari 4+; multiple color stops */ background-image:-webkit-gradient(linear, left bottom, left top, color-stop(0.20, red), color-stop(0.40, green), color-stop(0.6, blue), color-stop(0.8, purple), color-stop(1, orange)); /* chrome 10+, safari 5.1+ */ background-image:-webkit-linear-gradient(red, green, blue, purple, orange); /* firefox; multiple color stops */ background-image:-moz-linear-gradient(top, red, green, blue, purple, orange); /* ie10 */ background-image: -ms-linear-gradient(red, green, blue, purple, orange); /* opera 11.1 */ background-image: -o-linear-gradient(red, green, blue, purple, orange); /* The "standard" */ background-image: linear-gradient(red, green, blue, purple, orange); }
关于IE对CSS颜色渐变技术的支持做一些说明:在早期IE是使用filter和-ms-filter语法实现渐变色,而最新版的IE里改为了-ms-linear-gradient语法。我们可以使用CSS里条件判断语句来解决这个问题:
<!--[if lt IE 10]> <style> .gradientElement { filter: progid:DXImageTransform.Microsoft.gradient(startColorstr='#063053', endColorstr='#395873'); -ms-filter: "progid:DXImageTransform.Microsoft.gradient(startColorstr='#063053', endColorstr='#395873')"; } </style> <![endif]-->
