ok so im in the process of working out how to do this and have decided to put little notes like this when i finally get stuff done. So far i finally figured out why nothing was displaying. The trick is that even if the code is js, the mode still needs to be HTML or else you cant de-toggle the display source code button. Now stuff is showing up but withoug images. Going to tackle that next. (Possible problem of inserting map/ image)

protip #2. if the code doesnt work, it wont be recognized as proper code and will show up as plain text instead of script disabled. protip #3. the actual result wanted through the code will only show up after saving changes and exiting the edit mode

ok so i managed to get half of the map to work???? idk i think its a problem w the sizing or smth. that can prob be smoothed out tho. V EXCITED TO KNOW IT WORKS IN SQUARESPACE THO!

YAYYYYY i figured out why it was formating weird (w the help of my mom, props to her); essentially u need to add the css as the first code injection and then keep the mode in html (as mentioned b4 other types of code will only work in html mode bc of the ability to disable the source code display)
