<!DOCTYPE html> This is the declaration used to denote that the document is written in HTML5.
<html> This element represents the root, or base, for an HTML document. It contains all other elements.
<head> Contains metadata including the title of the document and links to stylesheets or scripts.
<title> Declares the document title that appears in the browser title bar or tab.
The content that appears in the browser window is placed within the <body> tag. Text, images, links, lists, and tables are included.
The <h1> tag is the largest heading size.
The <p> tag defines a paragraph.

There are three parts to an HTML element: the opening tag, the content, and the closing tag.
For example:

<tagname>Content goes here…</tagname>

HTML elements consist of the entire structure, from the opening tag to the closing tag.
Example

<h1>Welcome to HTML</h1>
<p>This is an example paragraph.</p>
