How to create Codecademy tooltips?

[data5047512279]

Hey y’all, first time posting in the forum, sorry if this is in the wrong place, etc. I did search before posting but please do point me in the right direction if this has been addressed already elsewhere.

Wondering about these tooltips we encounter throughout the front-end engineer path.



1. Although helpful, not looking for this:

@mtf

<span lang="fr"
      title="a policy or attitude of letting things take their
      own course, without interfering.">laissez faire</span>

2. Additionally, how to create that dot grid and use it as a shadow for stuff?

Thanks!

As for the shadow effect, that is likely a 16 pixel by 16 pixel SVG that is used to style it.
