How Typeform was built? Options

[shizeerr]

Hello, I need to know how can I do survey like Typeform.
I mean, how can I do this one thing or how it's called.

"Question text...." on the centre
<button> below...

and after I click button I will get second question on the same page etc.
Can I do it in HTML/CSS or I need JS too?

Type form survey for example: https://www.typeform.com/templates/t/produc...urvey-template/
