CSS Setup and Selectors: Multiple Classes

https://www.codecademy.com/courses/learn-css/lessons/css-setup-selectors/exercises/multiple-classes?action=resume_content_item

It has me change the font in < h1 > to uppercase using the style.css

My question is why go through the trouble of changing things to uppercase in CSS when I can more simply just type in all uppercase directly in the HTML file? It seems like it is just needlessly complicating things.

Thank you for any responses in advance!
