Help with Dasmoto's Arts & Crafts

Hello,

I am new to the coding world and I am working on my first independent project of HTML/CSS but I am having trouble viewing my work. I think I may be doing something wrong in the files I have organized in VSCode. Almost none of my work can be seen on the browser and there are a bunch of red marks on my coding in VSCode. Here are some screenshots. Thank you for your time.

Best,
Mahajoy
