Question

when i finished reading sections, i got cinfused on what content should have <article> or <section>

Answer 1

These tags are usually so that browser know what content is where … for e.g. in reader mode browser will display the content of article .
So like their name suggests article should be contain articles, section is like a div and idk about main.
