I am doing a page programming task, and for a long time I cannot solve the *" User Story #4: Each section element with the class of main-section should also have an id that corresponds with the text of each header contained within it. Any spaces should be replaced with underscores (e.g. The section that contains the header “JavaScript and Java” should have a corresponding id="JavaScript_and_Java" ).
In the CodePen editor for HTML, only the code between the two body tags should be written. Delete <!DOCTYPE html>, <html></html>, <head><and all tags between></head>, and <body></body> are not necessary.
If you need to put something in the <head> there is top right of the HTML editor a gear symbol for the settings. Click it and put there your <meta> tags etc.
