How do HTML headers work?

= = = = = hello =

hello HTML tags must be within the "<" and ">" symbols.the largest heading would be: h1 inside these symbols ("<" and ">") for an opening tag, the text you wish to format would then follow, and the closing tag /h1 within these symbols ("<" and ">") would end the tag. Heading size decreases as the number within the tag increases, with h1 being largest and h7 being smallest
