How to make a button visible?

Question

JavaScript

There is a button

<div><button type = "button" id = "but2" onClick = "">Пауза</button></div>

How to make it visible? In css, invisibility is described through visibilit, you need to make it visible through js

Answer 1

Change the rule in css, no?
If through js, then
but2.style.visibility = 'visible'

Answer 2

Of course, I'm wildly sorry, but if she is invisible, then how are you going to press her?
