Offline practices

Hey all,
hope you’re having a good day/night
I have a 16 hour flight in the next couple of days and I was wondering if there was any offline practices out there for me to download and work on during the flight ?
since I’m a newbie and need to grasp all I can of HTML and CSS

I don’t know of anyting in particular and i don’t know what kind of computer you have, but a google search for “learn html css offline” should turn something up.

way to be motivated, i would just sleep :stuck_out_tongue:
