HOW to make centre of a page in HTML

Answer 1

You can use align="center" attribute in the paragraph or headings you want to be aligned to the center, this however doesn't work in all elements, some elements like <svg>, <img> and <ul>, <ol>, <dl> I believe can be centered by putting them inside a paragraph aligned to the center. You can also use CSS to do that, but since you did not include CSS tag I guess you are only learning HTML for the moment.
