With the increasing use of mobile devices, it’s essential to create mobile-friendly websites. Use responsive design techniques to ensure that your website looks good and functions well on all devices.

6. Enhancing HTML with CSS and JavaScript

While HTML provides the structure and content of a web page, CSS (Cascading Style Sheets) is used for styling and layout, and JavaScript is used for adding interactivity.

6.1. CSS Basics

CSS allows you to control the appearance of your HTML elements. You can use CSS to change colors, fonts, sizes, and positioning.

Inline Styles: CSS styles can be applied directly to HTML elements using the style attribute.
```
<p style="color: blue;">This is a blue paragraph.</p>
```
Internal Styles: CSS styles can be defined in the <head> section of the HTML document using the <style> tag.
```
<head>
    <style>
        p {
            color: blue;
        }
    </style>
</head>
```
External Styles: CSS styles can be defined in a separate .css file and linked to the HTML document using the <link> tag.
```
<head>
    <link rel="stylesheet" href="styles.css">
</head>
```

6.2. JavaScript Basics

JavaScript is a programming language that allows you to add interactivity and dynamic behavior to your web pages.

Inline Scripts: JavaScript code can be added directly to HTML elements using event attributes.
```
<button onclick="alert('Hello!')">Click me</button>
```
Internal Scripts: JavaScript code can be defined in the <head> or <body> section of the HTML document using the <script> tag.
```
<script>
    function sayHello() {
        alert('Hello!');
    }
</script>
```
External Scripts: JavaScript code can be defined in a separate .js file and linked to the HTML document using the <script> tag.
```
<script src="script.js"></script>
```

6.3. Combining HTML, CSS, and JavaScript

HTML, CSS, and JavaScript work together to create modern web applications. HTML provides the structure, CSS provides the styling, and JavaScript provides the interactivity.

7. Best Practices for Writing Clean and Efficient HTML Code

Writing clean and efficient HTML code is crucial for maintainability, performance, and SEO.

7.1. Use Proper Indentation

Use proper indentation to make your HTML code more readable. Indent nested elements to show the structure of the document.

7.2. Use Comments

Use comments to explain your code. Comments are ignored by the browser but can help other developers (or yourself) understand the purpose of different sections of the code.

<!-- This is a comment -->

7.3. Validate Your HTML

Use an HTML validator to check your code for errors. The W3C Markup Validation Service is a free online tool that can help you validate your HTML.

7.4. Keep Your Code Organized

Keep your HTML, CSS, and JavaScript code organized in separate files. This makes it easier to maintain and update your website.
