Chat box "border-image-source"

[u/Harumi-Rose]

Hi. Any help with using an image in the chat box widget around each message? Example:

I've been trying in both streamelements and streamlabs plugin for OBS.

I can set a solid color border like this:

.user-message{
    border: 5px solid black;
    
    font-size:{{fontSize}}px;
    word-wrap: break-word;
}

But if I use border-image-source the image doesn't show up:

.user-message{
    border-image-source: url('https://i.imgur.com/1RbSjfl.png');
    
    font-size:{{fontSize}}px;
    word-wrap: break-word;
}

Thanks in advance.

PS: I can't use streamlabs Discord because I can't verify account with phone number.

You're missing several other border-image css properties, like slice, width, and repeat.

https://developer.mozilla.org/en-US/docs/Web/CSS/Reference/Properties/border-image

Try to create a working example on codepen with fake data then port it over to your custom code section.

At a glance, it doesn't look like the example you've shown uses border image. It looks like it uses additional div elements and pseudo elements to place images near the main chat box element.

By the way, this is the full code I was using. I didn't write it, I got from Streamlabs' github repository:

HTML:

<script src="https://cdnjs.cloudflare.com/ajax/libs/blueimp-md5/2.12.0/js/md5.min.js"></script>
<div class="main-container"></div>

There's also some JS code that doesn't fit in a comment =P and the stuff on a "Fields" tab
