HTML consists of elements, which are represented by tags enclosed in angle brackets, such as <p and </p for a paragraph.
The most important element in an HTML document is the <html element, which serves as the container for all other elements.
The <head element contains meta information about the document, such as the title, which is displayed in the browser’s title bar or tab, and links to other resources, such as stylesheets.
The <body> element contains the visible content of the web page, such as text, images, and videos.
Common layout and structural elements include: <header, <nav, <main, <article, <aside, <footer
HTML5 also introduce new semantic element, to define specific role and sections on the page, such as <header, <nav, <section, <article, <aside, <footer, <figcaption,
You can add visual styling to the HTML elements using Cascading Style Sheets (CSS).
