Overview
Semantic HTML uses tags that clearly describe their meaning in a human- and machine-readable way. For example, using <header> instead of <div class="header"> tells the browser and search engines exactly what that section represents.
Key Semantic Elements

<header>,<footer>,<main>,<nav>,<section>,<article>,<aside>. - Text:
<h1>-<h6>,<p>,<ul>,<ol>,<li>,<strong>,<em>. - Forms:
