# HTML Introduction
● HTML ?
HTML is the standard markup language for creating Web pages.
- HTML stands for Hyper Text Markup Language
- HTML describes the structure of Web pages using markup
- HTML elements are the building blocks of HTML pages
- HTML elements are represented by tags
- HTML tags label pieces of content such as "heading", "paragraph", "table", and so on
- Browsers do not display the HTML tags, but use them to render the content of the page
● A simple HTML Document.
- The
<!DOCTYPE html>declaration defines this document to be HTML5 - The
<html>element is the root element of an HTML page - The
<head>element contains meta information about the document - The
<title>element specifies a title for the document - The
<body>element contains the visible page content - The
<h1>element defines a large heading - The
<p>element defines a paragraph
● HTML Tags
HTML tags are element names surrounded by angle brackets.
<tagname>content goes here....</tagname>
- HTML tags normally come in pairs like <p> and </p>
- The first tag in a pair is the start tag, the second tag is the end tag
- The end tag is written like the start tag, but with a forward slash inserted before the tag name
● Web Browsers
The purpose of a web browser is to read HTML documents and display them.
The browser does not display the HTML tags, but uses them to determine how to display the document.
● HTML Page Structure
Below is a visualization of an HTML page structure.
● The <!DOCTYPE> Declaration
The <!DOCTYPE> declaration represents the document type, and helps browsers to display web pages correctly.
It must only appear once, at the top of the page.
The <!DOCTYPE> declaration is not case sensitive.
