HTML Introduction

What is HTML?

First of all, understand what is HTML?

HTML Stands for “Hyper Text Markup Language”. HTML is a markup language used to create web pages and web-based apps. When a web page is opened by a web browser, it receives a document from its web server as HTML, which is converted into a web browser multimedia web page.
It can also use CSS and JavaScript, which makes it even more useful. It can show or use any program written in JavaScript in web pages and CSS can also decide its appearance and size. The World Wide Web Consortium (W3C), which maintains the standard of HTML and CSS, is encouraging the use of CSS since 1997.
HTML Markup.

There are many essential things in the HTML markup, in which the tags (and their properties) are the main. Tags are mostly in groups of two. Such as <h1> and </ h1> header tags. In this, the first one is called an open tag and the second one is a closed tag. These are open tags initially, and then there are no text or other tags, and in the end, there is a tag closing the tag.

There are always open and closed tags not always open. There are several tags that are written in the form of just a tag and its properties are written in it. A similar tag is also <img>. Such tags do not have open and closed tags. They are used only by typing its properties in a tag. An example of a general HTML markup is given below.

Example of Simple HTML Document:

<!DOCTYPE html>
<title>This is a Title</title>

<h1>This is First Heading</h1>
<p>This is first paragraph.</p>


Example Explained:
  • The <!DOCTYPE html> defines this documents to be HTML5.
  • Everything coming between <html> and </ html>shows a web page.
  • The part between <body> and </ body> appears on the page itself.
  • The <h1> element defines a first heading.
  • The <p> element defines a paragraph.

HTML Tags:

HTML tag normally write in pairs like <h1> and </h1>
Here <h1> tag is start tag, while </h1> is end tag.
The end tag is written like the start tag, but difference is only that we insert forward salahbefore the tag name.
