Hide button plus code

ppp 1 month ago Technical Answers 29

I have 2 buttons that have the same class but different IDs. (id="1″ and id="2″)
To hide the button, this code works: button.classname { display: none;}
But it hides two buttons, can I specify the ID of the buttons in the css?
I just want to hide the first button id="1″
I tried using button.classname[id="1″] { display: none;}

😭😭😭😭😭 but it didn't work.
Is there a way to fix this?

What's the code?
