Hello!
I studied the topic of Event Objects, but found that the example from the given topic does not work correctly.
The first div element in the required field does not change its color.
Please check if the given code is really not working as it should or the problem is on my side.

Hi @Taiga!
It seems to work OK for me. I’m assuming you are reading about it at https://developer.mozilla.org/en-US/docs/Learn/JavaScript/Building_blocks/Events#event_objects ?
And you can find our live version at https://mdn.github.io/learning-area/javascript/building-blocks/events/useful-eventtarget.html
What browser are you using? I tested in Fx and Chrome.
