Right now I'm doing the Intro to HTML course on Khan Academy & finding it very useful as a beginner! Here's a link to my notes if you ever want to check them out without having to do a whole course (I've been told I take pretty good notes before so I'm hoping this will help others!): https://honeycitron.neocities.org/htmlnotes.txt
Oh, I should note that I've only just started so they aren't finished yet!
