Practical with HTML day by day

 




Dear viewers, A computer is a practical technology. If we learn only theory, then it will cause severe harm to us.

 


Day-1:  Practical Session

What is HTML?

  1. HTML stands for Hyper Text Markup Language
  2. HTML elements label pieces of content such as "this is a heading",
  3. HTML is the standard markup language for creating Web pages
  4. HTML describes well the structure of a Web page
  5. HTML consists of a series of elements
  6. HTML elements handle the browser how to display the content

"this is a paragraph", "this is a link", etc.

 

My First Simple HTML Page

<!DOCTYPE html>
<html>
<head>
<title>My First HTML Web Page</title>
</head>
<body bgcolor=’pink’>
<h1>My First Heading</h1>
<p>My first paragraph. </p>
</body>
</html>

=====================

 

Output

=====


Example Explained

  • The <!DOCTYPE html> declaration defines that this 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, how will look 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 or bigger in size
  • The <p> element defines a paragraph and its’ content

====================================


 Day-2:  Practical Session

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 tag

Element content

End tag

<h1>

My First Heading

</h1>

<p>

My first paragraph.

</p>

<br>

none

none

 Practical with HTML day by day

Note: Some HTML elements have no content (like the <br> element) are called empty elements.

 

HTML Page Structure

Below is a visualization of an HTML page structure:

 


Note: 

The content that is 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.

Now Full code is :

<!DOCTYPE html>

<html>

<head>

<title>My First HTML Web Page</title>

</head>

<body bgcolor='lightblue'>

<h1>This is a heading</h1>

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

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

</body>

</html>
