How do I implement this element on my website?

[Alejandro]

Hi all,

 

I've been looking into how to implement this accordion like element shown on this website (www.starlabel.com) without luck. I'm not sure which library/tool the developer is using to achieve it.

I've attached a picture of the exact section I'm talking about.

Thank!
