How do you use CSS and JavaScript to enhance the functionality and design of your HTML pages?

CSS (Cascading Style Sheets) is used to control the layout and design of HTML pages. With CSS, you can specify things like colors, fonts, and spacing, and apply them to specific HTML elements on your page. JavaScript, on the other hand, is a programming language that is used to add dynamic functionality to your HTML pages. With JavaScript, you can create things like interactive forms, animations, and dynamic content updates. Together, CSS and JavaScript can be used to create rich, interactive websites that provide a better user experience. To use CSS and JavaScript in your HTML pages, you would typically include them as separate files that are linked to or embedded in your HTML document. You can also add CSS and JavaScript directly to your HTML document using the <style> and <script> tags, respectively.
