Semantic HTML Structure in HTML

Semantic HTML describes meaning: <header>, <nav>, <main>, <section>, <article>, <aside>, <footer>. Screen readers and SEO benefit.

<header> is page/section intro. <nav> is navigation. <main> is primary content. <section> groups related content. <article> is standalone.

<aside> is supplementary (sidebar). <footer> is page/section end. Never use empty divs when semantic tags fit.
