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?

这是一个带有透明背景的渐变边界，使用边界半径
.gradient-border {
border-radius: 999px;
padding: 10px 3rem;
display: inline-block;
position: relative;
background: transparent;
border: none;
}
.gradient-border::before {
content: "";
position: absolute;
inset: 0;
padding: 2px;
border-radius: 9999px;
background: linear-gradient(87.36deg, blue 6.42%, red 84.24%),
linear-gradient(0deg, #FFFFFF, #FFFFFF);
-webkit-mask:
linear-gradient(#fff 0 0) content-box,
linear-gradient(#fff 0 0);
mask:
linear-gradient(#fff 0 0) content-box,
linear-gradient(#fff 0 0);
-webkit-mask-composite: xor;
mask-composite: exclude;
}

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 >
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%);
}
或者可以参考这个小提琴:http://jsfiddle.net/necolas/vqnk9/
试试下面的例子:
.border-gradient {
border-width: 5px 5px 5px 5px;
border-image: linear-gradient(45deg, rgba(100,57,242,1) 0%, rgba(242,55,55,1) 100%);
border-image-slice: 9;
border-style: solid;
}
