Introduction to html tutorial

What is HTML?

HTML is the language of the web. It is very important for both building web application and web pages. HTML stands for Hypertext Markup language combined with Cascading Style Sheets (CSS) and Javascript, it forms the basic technologies of the world wide web.

A SIMPLE HTML EXAMPLE Here is how an HTML code looks like

<!DOCTYPE html>
<html>
  <head>
    <title>Page Title</title>
  </head>
  <body>
    <h1>My First Heading</h1>
    <p>My first paragraph.</p>
  </body>
</html>

And here’s what the above code looks like in your web browser

breaking it down

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 indicates a title for the document
The <body> element contains the visible page content
The <h1> element defines a large heading
The  element defines a paragraph

HTML ELEMENT

A html element contains a tag, some content and an end tag. It is basically two tags with a content in between them. my second web page 

HTML TAGS

HTML tags are element names that usually come in pairs for example . The first tag is usually enclosed in a and the closing tags have a forward slash inserted before the tag name.

WEB BROWSER

The real function of the web browser (Chrome, Firefox, Safari, Microsoft Edge) is to read and display the HTML content correctly.

The browser does not display the tags, that would make the page really ugly but uses the tags to determine how to display the document.
