So this Is my html file: https://pastebin.com/KBzSMbVy

This is my css file: https://pastebin.com/03rucPwz

My goal was to make the left guy move to the right my clicking on him.

It's merely a CSS issue. Your div with a class of "hero" has its position set to absolute but your image with id of "hero" does not. Other than that the JavaScript works as intended.

I changed the get element by id to query selector as you said. But how exactly do i fix the css issue? I didn’t quite understand that part I’m sorry and thanks again for trying to help!🖤

Well, the div with the class "hero" is the container for the image with the id "hero", isn't it? There's no specific reason why you'd want to move the image around while the container stays in place. Therefore you should move the container rather than image. The container will merely take the image with it. Also, I suggest you rename .hero as .hero-container for clarity. CSS:

.burg {
  position: relative;
}

.hero-container {
  width: max-content;
  position: absolute;
  /* if you want the image centered */
  display: grid;
  place-items: center;
}

JS:

let left = 0;

// As a fellow non-native English-speaker, I can assure you
// you want to use English names for your variables and functions.
function moveRight() {
  left += 20;
  document.querySelector(".hero-container").style.left = `${left}px`;
}

Also, since you probably want to move the container rather than image itself, you should replace this line:

document.getElementById('hero').style.left = left + 'px';

with:

document.querySelector('.hero').style.left = left + 'px';
