A header is a line of text at the top of a page or section, or in sports like soccer, a hit of the ball using the head.
Formed from “head” plus the suffix “-er,” meaning something that heads or is at the head. Its uses in printing, documents, and sports all grow from this basic ‘top’ or ‘head’ idea.
In web pages, ‘headers’ (like H1, H2) quietly tell search engines and screen readers what’s important. So a simple word about “the top” now shapes how information is organized and found online.
