我试图应用一个渐变的边界,我认为这是简单的这样做:
border-color: -moz-linear-gradient(top, #555555, #111111);
但这并不奏效。
有人知道做边界渐变的正确方法吗?

试试这段代码
.gradientBoxesWithOuterShadows {
height: 200px;
width: 400px;
padding: 20px;
background-color: white;
/* outer shadows (note the rgba is red, green, blue, alpha) */
-webkit-box-shadow: 0px 0px 12px rgba(0, 0, 0, 0.4);
-moz-box-shadow: 0px 1px 6px rgba(23, 69, 88, .5);
/* rounded corners */
-webkit-border-radius: 12px;
-moz-border-radius: 7px;
border-radius: 7px;
/* gradients */
background: -webkit-gradient(linear, left top, left bottom,
color-stop(0%, white), color-stop(15%, white), color-stop(100%, #D7E9F5));
background: -moz-linear-gradient(top, white 0%, white 55%, #D5E4F3 130%);
}

这是一个很好的半跨浏览器的方法,有渐变边界,淡出一半。只需将颜色停止设置为rgba(0,0,0,0)
.fade-out-borders {
min-height: 200px; /* for example */
-webkit-border-image: -webkit-gradient(linear, 0 0, 0 50%, from(black), to(rgba(0, 0, 0, 0))) 1 100%;
-webkit-border-image: -webkit-linear-gradient(black, rgba(0, 0, 0, 0) 50%) 1 100%;
-moz-border-image: -moz-linear-gradient(black, rgba(0, 0, 0, 0) 50%) 1 100%;
-o-border-image: -o-linear-gradient(black, rgba(0, 0, 0, 0) 50%) 1 100%;
border-image: linear-gradient(to bottom, black, rgba(0, 0, 0, 0) 50%) 1 100%;
}
<div class="fade-out-border"></div>
用法解释:
Formal grammar: linear-gradient( [ <angle> | to <side-or-corner> ,]? <color-stop> [, <color-stop>]+ )

渐变边框来自Css-Tricks: http://css-tricks.com/examples/GradientBorder/
.multbg-top-to-bottom {
border-top: 3px solid black;
background-image: -webkit-gradient(linear, 0 0, 0 100%, from(#000), to(transparent));
background-image: -webkit-linear-gradient(#000, transparent);
background-image:
-moz-linear-gradient(#000, transparent),
-moz-linear-gradient(#000, transparent);
background-image:
-o-linear-gradient(#000, transparent),
-o-linear-gradient(#000, transparent);
background-image:
linear-gradient(#000, transparent),
linear-gradient(#000, transparent);
-moz-background-size: 3px 100%;
background-size: 3px 100%;
background-position: 0 0, 100% 0;
background-repeat: no-repeat;
}
而不是边框,我会使用背景渐变和填充。同样的外观,但更简单,更有支撑。
举个简单的例子:
.g { Background-image: -webkit-gradient(线性,左下,左上,彩色停止(0.33,rgb(14,173,173)),彩色停止(0.67,rgb(0,255,255))); 背景-图像:-moz-linear-gradient(中底,rgb(14,173,173) 33%, rgb(0,255,255) 67%); 填充:2 px; } .g > div{背景:#fff;} < div class = " g " > < div > bla < / div > < / div >
编辑:你也可以利用:before选择器@WalterSchwarz指出:
body { padding: 20px; } .circle { width: 100%; height: 200px; background: linear-gradient(to top, #3acfd5 0%, #3a4ed5 100%); border-radius: 100%; position: relative; text-align: center; padding: 20px; box-sizing: border-box; } .circle::before { border-radius: 100%; content: ''; background-image: linear-gradient(to bottom, #3acfd5 0%, #3a4ed5 100%); top: -10px; left: -10px; bottom: -10px; right: -10px; position: absolute; z-index:-1; } <div class="circle"></div>
为了获得跨浏览器支持,你也可以用:before或:after来模拟渐变边框,这取决于你想做什么。
试试这个,在web-kit上工作很好
.border { 宽度:400 px; 填充:20 px; border-top: 10px solid #FFFF00; border-bottom:10px solid #FF0000; 背景图片: 线性渐变(# FFFF00 # FF0000), 线性渐变(# FFFF00 # FF0000) ; background-size: 10 px 100%; 背景位置:0 0,100% 0; 平铺方式:不再重演; } < div class = "边境”>你好!< / div >
