Introduction to HTML
HTML stands for HyperText Markup Language. It is used to create web pages and web applications. HTML describes the structure of a web page using markup. HTML elements are the building blocks of HTML pages.
Basic HTML Structure
A basic HTML document includes the following structure:
<!DOCTYPE html>
<html>
<head>
<title>Page Title</title>
</head>
<body>
<h1>This is a Heading</h1>
<p>This is a paragraph.</p>
</body>
</html>
<!DOCTYPE html>
: Declares the document type and version of HTML.<html>
: The root element of an HTML page.<head>
: Contains meta-information about the document.<title>
: Sets the title of the document.<body>
: Contains the content of the HTML document.
HTML Elements
HTML elements are defined by a start tag, some content, and an end tag:
<tagname>Content goes here...</tagname>
For example:
<p>This is a paragraph.</p>
Attributes
Attributes provide additional information about HTML elements. They are always included in the opening tag and usually come in name/value pairs:
<tagname attribute="value">Content goes here...</tagname>
For example:
<a href="https://technestology.in/">This is a link</a>
Text Formatting
HTML provides various elements to format text:
- Headings:
<h1>
to<h6>
tags are used for headings. - Paragraph:
<p>
tag is used for paragraphs. - Bold:
<b>
or<strong>
tags make text bold. - Italic:
<i>
or<em>
tags make text italic.
Links and Images
Links and images are integral to web pages:
- Links: The
<a>
tag defines a hyperlink.
<a href="https://technestology.in/">Visit Example</a>
- Images: The
<img>
tag embeds an image in a web page.
<img src="image.jpg" alt="Description of Image">
Lists
HTML supports ordered and unordered lists:
- Unordered List: Uses
<ul>
and<li>
tags.
<ul>
<li>Item 1</li>
<li>Item 2</li>
<li>Item 3</li>
</ul>
- Ordered List: Uses
<ol>
and<li>
tags.
<ol>
<li>First item</li>
<li>Second item</li>
<li>Third item</li>
</ol>
Tables
Tables organize data in rows and columns:
<table>
<tr>
<th>Header 1</th>
<th>Header 2</th>
</tr>
<tr>
<td>Data 1</td>
<td>Data 2</td>
</tr>
</table>
Forms
Forms collect user input:
<form action="/submit" method="post">
<label for="name">Name:</label>
<input type="text" id="name" name="name">
<input type="submit" value="Submit">
</form>
Semantic HTML
Semantic HTML introduces meaning to the web page rather than just presentation:
<header>
,<footer>
,<article>
,<section>
, etc., give structure to the content.- These tags help with accessibility and SEO.
Multimedia
HTML5 introduced new tags for multimedia:
- Audio: The
<audio>
tag embeds sound content.
<audio controls>
<source src="audio.mp3" type="audio/mpeg">
Your browser does not support the audio element.
</audio>
- Video: The
<video>
tag embeds video content.
<video controls>
<source src="video.mp4" type="video/mp4">
Your browser does not support the video element.
</video>
