4 gradient borders in CSS

Question

I need help applying a gradient border on all the 4 sides of a box. I tried it, but it only works for two sides. After looking at all the links and SO answers I have got this:

 .test{ height:250px; border: 2px solid; border-image: linear-gradient(to left,rgba(78,137,176,1) 1%, rgba(115,192,85,1) 100%) 100% 0 100% 0/2px 0 2px 0; padding-top:50px; }

 <div class="test"> This is a box and I want borders for all the sides </div>

I would appreciate any help. I am trying something similar to the image below. Thank you.

Answer 1

Using background image: (produces the exact output as your image)

You seem to be having gradients that are different on each sides and so it is difficult to achieve this with the border-image property. You could try and mimic the behavior using background-image like in the below snippet.

Basically what the below snippet does is that it creates the gradient for each of the 4 sides as gradient background image strips and then uses background-position to place them on the correct location.

The transparent border on parent is a placeholder where the mimiced border would end up appearing. The background-origin: border-box makes the background of the element start from border-box area itself (and not padding-box or content-box ). These two are just extra steps to avoid the usage of unnecessary calc stuff in the background-position .

 .test { height: 250px; border: 2px solid transparent; background-image: linear-gradient(to right, rgb(187, 210, 224), rgb(203, 231, 190)), linear-gradient(to bottom, rgb(114, 191, 87), rgb(116, 191, 86)), linear-gradient(to left, rgb(204, 233, 187), rgb(187, 210, 224)), linear-gradient(to top, rgb(84, 144, 184), rgb(80, 138, 176)); background-origin: border-box; background-size: 100% 2px, 2px 100%, 100% 2px, 2px 100%; background-position: top left, top right, bottom right, bottom left; background-repeat: no-repeat; padding-top: 50px; }

 <div class="test"> This is a box and i want border for all the side </div>

Using border image: (produces a border on all 4 sides but not same output as your image)

The best output that you could get with border-image property would be the below but as you can see from the demo it is not exactly the same as your image (or the first snippet's output):

 .test { height: 250px; border: 2px solid; border-image: linear-gradient(to left, rgba(78, 137, 176, 1) 1%, rgba(115, 192, 85, 1) 100%); border-image-slice: 1; padding-top:50px; }

 <div class="test"> This is a box and i want border for all the side </div>

Answer 2

I realized this for myself in this way:

the background changes inside the background-image.

 div { width: 170px; height: 48px; border-style: solid; border-width: 2px; border-image-source: linear-gradient(to bottom, #fff042, #ff5451); border-image-slice: 1; background-image: linear-gradient(to bottom, #f9e6e6, #c5e0c3), linear-gradient(to bottom, #fff042, #ff5451); background-origin: border-box; background-clip: content-box, border-box; display: flex; align-items: center; justify-content: center; text-transform: uppercase; }

 <div>text</div>
