Try this, works fine on web-kit
.border { _x000D_
width: 400px;_x000D_
padding: 20px;_x000D_
border-top: 10px solid #FFFF00;_x000D_
border-bottom:10px solid #FF0000;_x000D_
background-image: _x000D_
linear-gradient(#FFFF00, #FF0000),_x000D_
linear-gradient(#FFFF00, #FF0000)_x000D_
;_x000D_
background-size:10px 100%;_x000D_
background-position:0 0, 100% 0;_x000D_
background-repeat:no-repeat;_x000D_
}
_x000D_
<div class="border">Hello!</div>
_x000D_
There is a nice css tricks article about this here: https://css-tricks.com/gradient-borders-in-css/
I was able to come up with a pretty simple, single element, solution to this using multiple backgrounds and the background-origin property.
.wrapper {
background: linear-gradient(#222, #222),
linear-gradient(to right, red, purple);
background-origin: padding-box, border-box;
background-repeat: no-repeat; /* this is important */
border: 5px solid transparent;
}
The nice things about this approach are:
Check it out: https://codepen.io/AlexOverbeck/pen/axGQyv?editors=1100
Try the below example:
.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;
}
Here's a nice semi cross-browser way to have gradient borders that fade out half way down. Simply by setting the color-stop to 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>

I agree with szajmon. The only problem with his and Quentin's answers is cross-browser compatibility.
HTML:
<div class="g">
<div>bla</div>
</div>
CSS:
.g {
background-image: -webkit-linear-gradient(300deg, white, black, white); /* webkit browsers (Chrome & Safari) */
background-image: -moz-linear-gradient(300deg, white, black, white); /* Mozilla browsers (Firefox) */
filter: progid:DXImageTransform.Microsoft.gradient(startColorstr='#ffffff', endColorstr='#000000', gradientType='1'); /* Internet Explorer */
background-image: -o-linear-gradient(300deg,rgb(255,255,255),rgb(0,0,0) 50%,rgb(255,255,255) 100%); /* Opera */
}
.g > div { background: #fff; }

It's a hack, but you can achieve this effect in some cases by using the background-image to specify the gradient and then masking the actual background with a box-shadow. For example:
p {
display: inline-block;
width: 50px;
height: 50px;
/* The background is used to specify the border background */
background: -moz-linear-gradient(45deg, #f00, #ff0);
background: -webkit-linear-gradient(45deg, #f00, #ff0);
/* Background origin is the padding box by default.
Override to make the background cover the border as well. */
-moz-background-origin: border;
background-origin: border-box;
/* A transparent border determines the width */
border: 4px solid transparent;
border-radius: 8px;
box-shadow:
inset 0 0 12px #0cc, /* Inset shadow */
0 0 12px #0cc, /* Outset shadow */
inset -999px 0 0 #fff; /* The background color */
}
From: http://blog.nateps.com/the-elusive-css-border-gradient
try this code
.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%);
}

For cross-browser support you can try as well imitate a gradient border with :before
or :after
pseudo elements, depends on what you want to do.
border-image-slice
will extend a CSS border-image gradientThis (as I understand it) prevents the default slicing of the "image" into sections - without it, nothing appears if the border is on one side only, and if it's around the entire element four tiny gradients appear in each corner.
border-bottom: 6px solid transparent;
border-image: linear-gradient(to right, red , yellow);
border-image-slice: 1;
instead of borders, I would use background gradients and padding. same look, but much easier, more supported.
a simple example:
.g {
background-image: -webkit-gradient(linear, left bottom, left top, color-stop(0.33, rgb(14,173,173)), color-stop(0.67, rgb(0,255,255)));
background-image: -moz-linear-gradient(center bottom, rgb(14,173,173) 33%, rgb(0,255,255) 67% );
padding: 2px;
}
.g > div { background: #fff; }
_x000D_
<div class="g">
<div>bla</div>
</div>
_x000D_
EDIT: You can also leverage the :before
selector as @WalterSchwarz pointed out:
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;
}
_x000D_
<div class="circle"></div>
_x000D_
Try this, it worked for me.
div{_x000D_
border-radius: 20px;_x000D_
height: 70vh;_x000D_
overflow: hidden;_x000D_
}_x000D_
_x000D_
div::before{_x000D_
content: '';_x000D_
display: block;_x000D_
box-sizing: border-box;_x000D_
height: 100%;_x000D_
_x000D_
border: 1em solid transparent;_x000D_
border-image: linear-gradient(to top, red 0%, blue 100%);_x000D_
border-image-slice: 1;_x000D_
}
_x000D_
<div></div>
_x000D_

Another hack for achieving the same effect is to utilize multiple background images, a feature that is supported in IE9+, newish Firefox, and most WebKit-based browsers: http://caniuse.com/#feat=multibackgrounds
There are also some options for using multiple backgrounds in IE6-8: http://www.beyondhyper.com/css3-multiple-backgrounds-in-non-supportive-browsers/
For example, suppose you want a 5px-wide left border that is a linear gradient from blue to white. Create the gradient as an image and export to a PNG. List any other CSS backgrounds after the one for the left border gradient:
#theBox { background: url(/images/theBox-leftBorderGradient.png) left no-repeat, ...; }
You can adapt this technique to top, right, and bottom border gradients by changing the background position part of the background
shorthand property.
Here is a jsFiddle for the given example: http://jsfiddle.net/jLnDt/
Webkit supports gradients in borders, and now accepts the gradient in the Mozilla format.
Firefox claims to support gradients in two ways:
IE9 has no support.
Mozilla currently only supports CSS gradients as values of the background-image property, as well as within the shorthand background.
