How can i understand tags better

Answer 1

Just learn and practice HTML.
When you see a certain tag you should ask yourself (and Google) these questions:
1. What does the tag do?
2. What is it for?
3. Does it have default style and what is it?
4. Are there any similar tags?
5. Is it a self-closing tag and why is it a self-closing tag?
Finding answers to these questions will lead you to a better understanding of the tag.
