MDN web doc help isn't showing?

Hi, i’m really new to this but before when my cursor hovered over certain thing I got an option to click and it would take me to this MDN mozilla page which was helpful for me to learn a bit more, but nothing appears at the moment no matter where I hover my cursor?


I don’t think there are external link in the challenges at this time. You can always go to the MDN yourself and find the topic there to learn more.

There was last week, that’s how I found out about it? when I was typing an auto fill thing came and I think I got through to the MDN from clicking links there? Cheers

the MDN is a website, just reach it trough google or something…
or google the thing you want to learn more about
