As the title states, is it possible to make a gradient border in CSS3 and if so how? I know that you can make gradient backgrounds and there are many generators for that, bu

Answer 1

i used the span element instead to use as border by setting its css property. below is my code

<div id="main_container">
        <div class="tl"></div>
        <div class="tr"></div>
        <div class="bl"></div>
        <div class="br"></div>
        <span class="borderH"></span>
        <span class="borderV"></span>
</div>

n here is my css -

   #main_container{
    position:relative;
    width:480px;
    height:480px;
    background:#f9f9f9;
    border:1px solid #ff0000;
    left:20%;
    top:100px;
}
.tl { position: absolute; top: 0; left: 0; /*background: #ff0000;*/ border-right:1px none #000;width:50%;height:50%;  }
.tr { position: absolute; top: 0; left: 50%;/*background: blue;*/ border-bottom:1px none #000;width:50%;height:50%;}
.bl { position: absolute; top: 50%; left: 0; /*background: yellow;*/ border-top:1px none #000;width:50%;height:50%; }
.br { position: absolute; top: 50%; left: 50%; /*background: #80ff80;*/border-left:1px none #000;width:50%;height:50%; } 
.borderH{
    position: absolute; left: 0; top: 50%;height:1px;width:100%;
    background: -webkit-linear-gradient(left, #ff0000 , #80ff80); /* For Safari */
    background: -o-linear-gradient(right, #ff0000, #80ff80); /* For Opera 11.1 to 12.0 */
    background: -moz-linear-gradient(right, #ff0000, #80ff80); /* For Firefox 3.6 to 15 */
    background: linear-gradient(to right, #ff0000 , #80ff80); /* Standard syntax (must be last) */
}
.borderV{
    position: absolute; top: 0; left: 50%;width:1px;height:100%; 
    background: -webkit-linear-gradient(top, #ff0000 , #80ff80); /* For Safari */
    background: -o-linear-gradient(bottom, #ff0000, #80ff80); /* For Opera 11.1 to 12.0 */
    background: -moz-linear-gradient(bottom, #ff0000, #80ff80); /* For Firefox 3.6 to 15 */
    background: linear-gradient(to bottom, #ff0000 , #80ff80); /* Standard syntax (must be last) */
}

this code will generate the output like this https://drive.google.com/file/d/0B2sRswnexZtfUVlTM0t2dWI3cjA/edit?usp=sharing

Answer 2

Here's a solution that creates a colorful gradient border, like you can see at the top of sites such as Gumroad or Vimeo, e.g.:

<div class="u-border-top-rainbow">Lorem ipsum fu fu ma li ma coco go yo.</div>

.u-border-top-rainbow {
  border-style: solid;
  border-width: 30px 0 0 0;

   /* For a gradient repeated 3 times */
  border-image-source: repeating-linear-gradient(to right,
    hsla(   8,  78%, 63%, 1.00 ) 00.00%,
    hsla(   8,  78%, 63%, 1.00 ) 03.03%,
    hsla(   9,  85%, 58%, 1.00 ) 03.03%,
    hsla(   9,  85%, 58%, 1.00 ) 06.06%,
    hsla(  12, 100%, 47%, 1.00 ) 06.06%,
    hsla(  12, 100%, 47%, 1.00 ) 09.09%,
    hsla( 352,  70%, 47%, 1.00 ) 09.09%,
    hsla( 352,  70%, 47%, 1.00 ) 12.12%,
    hsla( 355,  76%, 38%, 1.00 ) 12.12%,
    hsla( 355,  76%, 38%, 1.00 ) 15.15%,
    hsla(   2,  78%, 32%, 1.00 ) 15.15%,
    hsla(   2,  78%, 32%, 1.00 ) 18.18%,
    hsla( 183, 100%, 30%, 1.00 ) 18.18%,
    hsla( 183, 100%, 30%, 1.00 ) 21.21%,
    hsla( 183,  95%, 27%, 1.00 ) 21.21%,
    hsla( 183,  95%, 27%, 1.00 ) 24.24%,
    hsla( 183, 100%, 22%, 1.00 ) 24.24%,
    hsla( 183, 100%, 22%, 1.00 ) 27.27%,
    hsla(  43,  92%, 54%, 1.00 ) 27.27%,
    hsla(  43,  92%, 54%, 1.00 ) 30.30%,
    hsla(  38, 100%, 48%, 1.00 ) 30.30%,
    hsla(  38, 100%, 48%, 1.00 ) 33.33%
  );

  border-image-slice: 1;
}

Codepen: Colorful CSS gradient border, à la Gumroad or Vimeo

The gradient could be written in half the size with the double stop notation, in this fashion:

background: linear-gradient(to right, red 20%, orange 20% 40%, yellow 40% 60%, green 60% 80%, blue 80%);

…unfortunately, such syntax is not supported by Safari as of yet.

Answer 3

here is an example of a gradient border that would work under Firefox:

#gradbor {
    border: 8px solid #000;
    -moz-border-bottom-colors: #555 #666 #777 #888 #999 #aaa #bbb #ccc;
    -moz-border-top-colors: #555 #666 #777 #888 #999 #aaa #bbb #ccc;
    -moz-border-left-colors: #555 #666 #777 #888 #999 #aaa #bbb #ccc;
    -moz-border-right-colors: #555 #666 #777 #888 #999 #aaa #bbb #ccc;
    padding: 5px 5px 5px 15px;
}

Try something like that in your CSS for it to work.

EDIT: I'm not sure if it will work at all on other browsers.

Answer 4

Border with linear gradient.

HTML

<div id="input_parameters">
        ...Some HTML...
</div>

CSS

#input_parameters {
border: 10px solid transparent;

border-image: linear-gradient(#1e2d61 0%,#1f386e 19%,#203c72 20%,#203c73 20%,#266aa8 69%,#2775b5 84%,#2878b9 84%,#2879ba 85%,#297fc0 95%,#2d75ad 100%);

-webkit-border-image: -webkit-linear-gradient(#1e2d61 0%,#1f386e 19%,#203c72 20%,#203c73 20%,#266aa8 69%,#2775b5 84%,#2878b9 84%,#2879ba 85%,#297fc0 95%,#2d75ad 100%);

border-image-slice: 1;
}

Answer 6

Here is a possibility to create a gradient shadow border with CSS3:

-webkit-border-radius: 10px;
   -moz-border-radius: 10px;
    -ms-border-radius: 10px;
        border-radius: 10px;

border: 4px solid rgba(0,0,0,.5);
-webkit-box-shadow: inset 0 0 20px #000;
   -moz-box-shadow: inset 0 0 20px #000;
    -ms-box-shadow: inset 0 0 20px #000;
        box-shadow: inset 0 0 20px #000;

Practically this will create an inner shadow border with 10px radius at the edges.
