Introduction
HTML, or HyperText Markup Language, is the standard markup language used to create web pages. Developed in 1990 by Tim Berners-Lee, HTML forms the foundation of the World Wide Web. It enables web developers to structure content and embed multimedia, linking the web's vast array of information in a coherent and accessible manner.
Structure of an HTML Document
An HTML document consists of elements that describe the content and its structure. These elements are enclosed in tags, typically written as opening <tag> and closing </tag> pairs.
Here's a basic example of an HTML document:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>My First HTML Page</title>
</head>
<body>
<h1>Welcome to My Website</h1>
<p>This is a paragraph of text on my first HTML page.</p>
</body>
</html>
Copy code
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <title>My First HTML Page</title> </head> <body> <h1>Welcome to My Website</h1> <p>This is a paragraph of text on my first HTML page.</p> </body> </html>
Key Components of HTML
HTML Elements and Attributes
HTML elements can have attributes that provide additional information. Attributes are included in the opening tag and have a name and value, such as class="classname" or id="idname".
For example:
<a target="_blank">Visit Example</a>
<img src="image.jpg" alt="Description of image">
Copy code
<a target="_blank">Visit Example</a> <img src="image.jpg" alt="Description of image">

Semantic HTML
Semantic HTML introduces meaning to web content. Elements like <article>, <section>, <nav>, and <footer> improve accessibility and SEO by clearly defining the structure and purpose of content sections.
For example:
<article>
<header>
<h1>Article Title</h1>
<p>By Author Name</p>
</header>
<section>
<p>This is the main content of the article.</p>
</section>
<footer>
<p>Published on: 2024-05-20</p>
</footer>
</article>
Copy code
<article> <header> <h1>Article Title</h1> <p>By Author Name</p> </header> <section> <p>This is the main content of the article.</p> </section> <footer> <p>Published on: 2024-05-20</p> </footer> </article>
HTML Forms
Forms in HTML allow for user input and interaction. They are created using the <form> element and can include various input types like text fields, radio buttons, checkboxes, and submit buttons.
Example of a simple form:
<form action="/submit-form" method="post">
<label for="name">Name:</label>
<input type="text" id="name" name="name">
<label for="email">Email:</label>
<input type="email" id="email" name="email">
<input type="submit" value="Submit">
</form>
Copy code
<form action="/submit-form" method="post"> <label for="name">Name:</label> <input type="text" id="name" name="name"> <label for="email">Email:</label> <input type="email" id="email" name="email"> <input type="submit" value="Submit"> </form>
