htmlCopy code<!DOCTYPE html>
<html>
<head>
<title>Your Page Title</title>
</head>
<body>
<h1>Hello, World!</h1>
</body>
</html>
<!DOCTYPE html>: Declares the document type.<html>: The root element.<head>: Contains meta-information about the document.<title>: Sets the title of the page.<body>: Contains the content of the document.
Common HTML Tags

<h1> to <h6>: Headings, with<h1>being the highest level and<h6>the lowest.<p>: Paragraphs.<a>: Links.<img>: Images.<ul>and<li>: Unordered lists and list items.<div>: Division or section of the document.
Creating Your First HTML Page
To create your first HTML page:
- Open a text editor (like Notepad, VS Code, or Sublime Text).
- Write the basic HTML structure.
- Save the file with a
.htmlextension (e.g.,index.html). - Open the file in a web browser to view your webpage.
Getting Started with CSS
What is CSS and How Does It Work?
CSS (Cascading Style Sheets) is a language used to describe the presentation of an HTML document. It controls the layout, colors, fonts, and overall style of the webpage. CSS can be added inline, internally within an HTML document, or externally in a separate file.
Adding CSS to Your HTML
There are three ways to add CSS to your HTML:
- Inline CSS: Directly within an HTML element using the
styleattribute.htmlCopy code<h1 style="color:blue;">Hello, World!</h1> - Internal CSS: Within a
<style>tag in the<head>section.htmlCopy code<head> <style> body { background-color: lightblue; } </style> </head> - External CSS: In a separate CSS file linked to the HTML document.htmlCopy code
<head> <link rel="stylesheet" href="styles.css"> </head>
Basic CSS Syntax and Selectors
CSS syntax consists of a selector and a declaration block:
cssCopy codeselector {
property: value;
}
For example, to change the color of all paragraphs to blue:
cssCopy codep {
color: blue;
}
Building Your First Webpage
Setting Up Your Development Environment

<header>
<h1>Welcome to My Website</h1>

cssCopy codebody {
font-family: Arial, sans-serif;
background-color: #f0f0f0;

padding: 0;
}
header {

</section>
Testing and Debugging
