First things first. Calm down, relax you got this!
Remember, the first thing you need to do in your project is to open the text editor and create a .html file and a .css file. You can go and create a .js file but i don’t think you should do that since you can do this with simple html and css.
The first user story tells us that “My tribute page should have an element with a corresponding id="main" , which contains all other elements.”, so when you are coding the project, you should have an element that have the id tag with “main”. Give it a go!
If you still can’t tackle this project, than it’s best to go back and learn the basics. There is nothing wrong going back if it means going foward !
