[Attila] Editing front page to mimic another theme

Hi folks,

I’m completely new to this and I’m wondering if there’s a specific way to create posts similar to this website? https://til.hashrocket.com/

I’ve no clue how to read code specifically but is there a simple way to mimic it using the Attila theme? (GitHub - zutrinken/attila: Ghost Theme). This is the closest and most similar theme that can relate to the above.

Ideally, it would be great to extend the amount of text that shows in the preview and even show code formatted snippets if possible. Hope this makes sense.

Pictures for reference
This has the entire post plus a good picture with code formatting:

Attila doesn’t as it truncates after 2 lines of text.
