There are couple way to do it.
1. Through JavaScript. Note that querySelectorAll return list of elements, therefore a loop is required to iterate all the elements in it.

JavaScript

function myFunction() {  
    document.querySelectorAll('h1, h2').forEach(function(tag) {
      tag.innerHTML = tag.innerHTML.toUpperCase();
	}); 
}

myFunction() ;

2. CSS

CSS

h1, h2 {
  text-transform: uppercase;
}
