Introduction to Web-Development (Part 1)

Introduction to Web-Development (Part-1) | Written By Manish Kumar

This is the first part of a series written by Manish Kumar of an introduction to Web-Development. He is going to give us a very detailed guide about the History, Applications and Hands-On of Web-development.

¿What is Web Development?

Web development is the work involved in developing a Web site for the Internet (World Wide Web) or an intranet (a private network).

Among Web professionals, “Web development” usually refers to the main non-design aspects of building Web sites: writing markup and coding.

The Three Types of Web Developers (and What They Do):

-The Front-End Developer (aka Front-End Engineer aka “Web Developer / Designer”)

-The Back-End Developer (aka the person no one really knows about)

-The Full-Stack Developer (aka the Superman / Superwoman) 

So basically we gonna talk about one of the most used web development language that’s HTML 

¿What is HTML5?

HTML stands for Hyper Text Markup Language.

HTML is the standard markup language for creating Web pages.

HTML describes the structure of a Web page.HTML consists of a series of elements.

HTML elements tell the browser how to display the content

HTML elements label pieces of content such as “this is a heading”, “this is a paragraph”, “this is a link”, etc.

¿Why we should use html5?

HTML5 coding is clear, simple, and descriptive. HTML5 also makes placing audio and video content a breeze.

It treats that content the same as it would with image tags, and this makes things a lot easier on coders because it allows them to include those multimedia elements without having to use a plugin or API.

I would suggest you to use “notepad++” as text editor for the language since is easy to use and implement.

It’s free software to use.

just download from your respective browser and you are ready to start with your first basic program.

Don’t forget to opt for HTML language from toolbar since it is applicable to all programming languages.

A First Simple HTML Document

<!DOCTYPE html>
<html>
<head>
<title>Page Title</title>
</head>
<body>

<h1>My First Heading</h1>
<p>My first paragraph</p>

</body>
</html>

Example Explained:

  • The <!DOCTYPE html> declaration defines that this document is an HTML5 document
  • The <html> element is the root element of an HTML page
  • The <head> element contains meta information about the HTML page
  • The <title> element specifies a title for the HTML page (which is shown in the browser’s title bar or in the page’s tab)
  • The <body> element defines the document’s body, and is a container for all the visible contents, such as headings, paragraphs, images, hyperlinks, tables, lists, etc.
  • The <h1> element defines a large heading
  • The <p> element defines a paragraph

¿What is an HTML Element?

An HTML element is defined by a start tag, some content, and an end tag:

<tagname>Content goes here…</tagname>

The HTML element is everything from the start tag to the end tag:

<h1>My First Heading</h1>

<p>My first paragraph.</p>

Start tagElement contentEnd tag
<h1>My First Heading</h1>
<p>My first paragraph.</p>
<br>nonenone

Note: Some HTML elements have no content (like the <br> element). These elements are called empty elements. Empty elements do not have an end tag!.

Web Browsers

The purpose of a web browser (Chrome, Edge, Firefox, Safari) is to read HTML documents and display them correctly.

A 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:

<html>

<head>

<title>Page title</title>

</head>

<body>

<h1>This is a heading</h1>

<p>This is a paragraph.</p>

<p>This is another paragraph.</p>

</body>

</html>

Note: The content inside the <body> section will be displayed in a browser. The content inside the <title> element will be shown in the browser’s title bar or in the page’s tab.

HTML History

Since the early days of the World Wide Web, there have been many versions of HTML:

YearVersion
1989Tim Berners-Lee invented www
1991Tim Berners-Lee invented HTML
1993Dave Raggett drafted HTML+

Resume

So basically we learnt basics of our first web page using html5.

This is a lot easier than you guys can think.

Try playing around with the code and who knows you get to know more about it.

Stay tuned we gonna come up with more tutorial next time regarding html5.

Keep practicing stay healthy and code.

Thank you for your time (Manish Kumar).
