I am quite stumped since i copied the code from the solution and it still won’t work. The concept seemed self-explanatory to me and i both typed in the solution and copied it, but it still won’t be accepted.
Maybe I’m just being stupid and overlooking something simple, but i don’t seem to find the issue.
Sometimes it can be related to the version of the browser you are using, also if the zoom of the page is different than 100% or, as said @tori-pak, that you are maybe using extensions such as Adblock or dark mode. Just in case the next time you meet a trouble maybe it can help too
