HTML Video (<video>, controls, autoplay, loop, src)
What is HTML Video?
The <video> element allows you to embed video content on a webpage. It
can play multiple formats (e.g., MP4, WebM, OGG) and includes attributes that
control playback behavior.
Why is HTML Video Important?
- User Engagement:
Videos increase user interaction on your page.
- Content Presentation:
Videos are effective for tutorials, product demos, or entertainment.
- Flexible Playback Control: With the controls attribute, users can control playback.
Key Attributes:
- controls:
Displays video controls like play, pause, and volume.
- autoplay:
Automatically starts playing the video when the page is loaded.
- loop:
Repeats the video once it finishes playing.
- src:

Code Example:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>HTML Video Example</title>
</head>
<body>
<h1>Watch This Cool Video</h1>
<video width="600" controls autoplay loop>
<source src="your-video.mp4" type="video/mp4">
Your browser does not support the video element.
</video>
</body>
</html>
Explanation:
- <video>: Embeds a video player directly into the webpage.

Adds play/pause and volume control to the video player.
- autoplay:
Starts the video as soon as it loads.
- loop:
Makes the video repeat continuously.

12.
HTML Iframes (<iframe>)
What is an HTML Iframe?
The <iframe> element is used to embed another HTML document or external
content within the current page. It can display content like videos, maps, or
entire webpages.
Why is HTML Iframe Important?
- Embedding External Content: You can embed other websites, videos, or maps, saving
space.
- Interactive Content:
It is great for interactive elements such as YouTube videos or Google
Maps.
- Flexibility:
Iframes can show dynamic content from other sources without navigating
away from the page.
Key Attributes:
- src:
Specifies the URL of the content to embed.
- width and height:
Control the size of the iframe.
- allowfullscreen:
Lets the embedded content go full-screen (especially for videos).
Code Example:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Embedding YouTube Video</title>
</head>
<body>
<h1>Watch this awesome YouTube Video</h1>
<iframe width="560" height="315" src="https://www.youtube.com/watch?v=FYErehuSuuw" frameborder="0" allowfullscreen></iframe>
</body>
</html>
Explanation:
- <iframe>: Embeds an external webpage or media like YouTube
videos directly into your page.
- src:
Specifies the URL to the external content (a YouTube video link here).
- allowfullscreen:
Ensures that the video can be viewed in full-screen mode.
- width and height:
Control the size of the embedded content.
13.
HTML Block and Inline Elements
What Are Block and Inline Elements?
HTML elements are divided into two categories: block and inline elements.
- Block Elements:
Take up the full width of their parent container and push subsequent
elements to the next line (e.g., <div>,
<p>, <h1>).
- Inline Elements:
Only take up as much space as needed and do not push other content to the
next line (e.g., <span>, <a>, <b>).
Why Are Block and Inline Elements
Important?
- Content Layout:
Understanding these elements helps with proper page structure and design.
- Flexibility:
Block elements are useful for structuring layouts, while inline elements
are useful for styling parts of a content block.
Code Example:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Block vs Inline Elements</title>
</head>
<body>
<!-- Block Element -->
<div style="background-color: lightgray; padding: 10px;">
<h2>This is a Block Element</h2>
<p>Block elements take up the full width and start on a new line.</p>
</div>
<!-- Inline Element -->
<p>This is a <span style="color: red;">inline</span> element within a paragraph.</p>
</body>
</html>
Explanation:
- Block Element (<div>): Takes up the full width and forces subsequent elements
onto a new line.
- Inline Element (<span>): Only takes up the space of the content inside it,
without affecting surrounding elements.
14.
HTML Div Element (<div>)
What is the <div> Element?
The <div> element is a block-level container used to group other
elements. It does not have any intrinsic meaning but is essential for styling
and organizing content.
Why is the <div> Element Important?
- Organize Content:
It groups related content together for easy styling or scripting.
- Layout Control:
Often used in conjunction with CSS to create layouts and structures for
websites.
Key Attributes:
- class:
Assigns a class for styling purposes.
- id:
Assigns a unique identifier for targeting with CSS or JavaScript.
Code Example:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>HTML Div Example</title>
<style>
.container {
width: 80%;
margin: 0 auto;
padding: 20px;
background-color: lightblue;
}
</style>
</head>
<body>
<div class="container">
<h2>Content within a div</h2>
<p>This content is grouped together inside a <code><div></code> element.</p>
</div>
</body>
</html>
Explanation:
- <div
class="container">:
Groups the content for styling purposes.
- CSS: Used to style the container (e.g., setting the width,
padding, and background color).
15.
HTML Span Element (<span>)
What is the <span> Element?
The <span> element is an inline container used for grouping inline
content. It is often used for applying styles or JavaScript to small portions
of text within larger content blocks.
Why is the <span> Element Important?
- Text Styling:
Perfect for targeting specific parts of content without breaking the
layout.
- Inline Grouping:
Unlike <div>, it does not create a line break, making it ideal for
inline text styling.
Key Attributes:
- class:
Assigns a class to the span for styling purposes.
- id:
Assigns a unique identifier for targeting.
Code Example:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>HTML Span Example</title>
<style>
.highlight {
color: blue;
font-weight: bold;
}
</style>
</head>
<body>
<p>This is a <span class="highlight">highlighted</span> text in the middle of a paragraph.</p>
</body>
</html>
Explanation:
- <span>: Used to wrap a portion of text (e.g.,
"highlighted") and apply specific styles without breaking the
flow of the surrounding text.
- CSS:
The .highlight class applies blue color and bold weight to the text.
Mini-Project: Creating a Personal
Webpage
Objective: The goal of this mini-project is to use the HTML elements
you have learned to create a fully functional and interactive personal webpage.
You will combine headings, paragraphs, images, lists, tables, links, forms, and
multimedia elements, all while organizing your content in a logical and
aesthetically pleasing way.
Project Steps:
- Page Title & Main Heading:
- Use the <h1>
tag to create a main title for your webpage, such as "Welcome to My
Personal Page."
- Below that, create multiple subheadings using <h2>, <h3>, etc., to organize different sections like
"About Me," "Hobbies," and "Contact Info."
- Personal Introduction Paragraph:
- Add a <p> tag beneath your main heading that includes a short introduction
about yourself. You can format some text with <b> for bold, <i>
for italic, and <u> for underline to emphasize key points.
- List of Hobbies:
- Create an unordered list (<ul>) of your hobbies or interests. Use the <li> tag to list each one, such as "Reading,"
"Traveling," "Photography."
- Also, create an ordered list (<ol>) of your top 5 favorite books, ranking them from 1 to
5.
- Table of Your Favorite Movies:
- Create a table to display information about your top 3
favorite movies, including the movie title and the director name. Use <table>,
<tr>, <th>, and <td> for structuring the table.
- Add a <caption> tag to give your table a title like "Favorite
Movies."
- Personal Image:
- Include an image of yourself (or a placeholder image)
using the <img> tag. Make sure to provide a proper alt attribute that describes the image for accessibility.
- Contact Form:
- Include a contact form with an input field for the
username, email address, and a textarea for them to leave a message.
- Add a submit button to allow users to submit their
information.
- Audio and Video Embeds:
- Embed an audio clip that you like (e.g., a song or
podcast) using the <audio> tag, with controls so users can play, pause, and
adjust volume.
- Also, embed a short video of yourself or an
inspirational video using the <video>
tag.
- Links to External Websites:
- Add at least two links to external websites you like
(e.g., social media profiles or your favorite blog), using the <a> tag with the href
attribute.
- Footer Section:
- Create a footer with information like your contact
details, copyright notice, or a short tagline. You can use <footer> or simply <div>
to structure this part.
Final HTML Example:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>My Personal Webpage</title>
