Is this FAQ layout possible with CSS?

Is this type of layout possible?

Reference site: https://lucia.soulkynd.com/experience

I want the questions on the left, and answers shown on the right. When the respective question is being clicked on the left, the text on the right would change. I have attached an image before for reference.

Would I be able to achieve this on Squarespace? 😮 Thank you so much!

I have a quick demo, you try checking, if it is what you want, I can write a quick guide on how to do it.

Here I haven't added border, arrow...but we can use some simple lines of CSS code to add it.
