Ugly buttons in Unity2D and how to improve them?

Question

C++ / C#

Hello! Don't throw stones, I'm just learning( The
question arose how to add normal buttons to the scene (and not what Unity creates with new rect (///)) + they are more convenient to arrange, as for me. And how to add them to the script? I know about Button Name = New Button; (or something similar), but where to put it (as in the case of a script where we create a button ourselves. Where? To an empty object?) and sometimes it does not work.
Also, the question is, if I want to make a menu (appearing-disappearing), then I need to make a Boolean variable into which to fill in Name.OnClick, constantly check it and based on it already show / hide menus? Then do the same with clicks on missing buttons? Check Button. OnClick and a boolean variable, or does the principle work - I can't see, therefore I can't click?
And yet, if these seemed easy to you - what to do with the slider?
PS I know about the UI, but it's ugly and incomprehensible.

Answer 1

I mean UI is ugly? You create it through the GameObject->UI->Button menu and replace it in the Image component with the beauty that you need. Through the script - in approximately the same way - you create a game object, add Button, Image components and so on to it.
