How to add Copy to Clipboard Icon in prismjs?

I followed this article - A complete guide to code snippets

I was able to setup the code block and copy to clipboard button.

But it looks ugly, compared to Ghost styling.

Here are my settings in prismjs - prismjs settings

Does anyone know the settings and color codes for replicating Ghost’s code block design with the icon & code type showing by default?

Hi Anirudh,
It looks like no one responded to your question.
I found this Ghost article helpful in adding color to my snippets.
I used method one and injected the suggested code into my header’s and footer’s and it works great!
One thing to note is, your snippets won’t have color in preview, only when you view the actual post.
I hope this helps!
Kind regards,
Ted
