Why does this (event handler) doesn't work? [Solved ✅]

Question

Why does this (the event handler) doesn't work? According to w3school, they said, "In HTML event handlers, this refers to the HTML element that received the event," but when I used them, they don't work. In Khan Academy, it worked, but in solo-learn, it didn't.

Here's the code if you want the whole thing:

Thank you! .■. for answering, but I found my answer on the comments on the project.
Ipang commented, "'this' in function refers to 'window' object, use 'event.target' in place of 'this'

Thank you Ipang for the answer!
