You'll use HTML to define elements like headings, paragraphs, images, and links. Get comfortable with different HTML tags and how they create the layout of a page. You can find lots of interactive tutorials and documentation online to practice.

CSS (Cascading Style Sheets) is all about the presentation – making your website look good. It's the stylist that adds color, fonts, and layout to your HTML structure. With CSS, you can control everything from the size and color of your text to the spacing between elements and the overall look and feel of your site. Experiment with different CSS properties and selectors to see how they affect the appearance of your web page. There are tons of online resources and CSS frameworks (like Bootstrap and Tailwind CSS) to help you get started. JavaScript brings your website to life. It's the scripting language that adds interactivity and dynamic behavior. With JavaScript, you can create things like animations, form validation, and interactive maps. You'll use JavaScript to handle user input, make requests to the server, and update the content on your page without requiring a full page reload. JavaScript can seem intimidating at first, but with practice and perseverance, you'll be writing interactive web applications in no time.

Understanding these three technologies and how they work together is crucial for any aspiring web developer. They form the basis of almost everything you'll do in web development, so make sure you have a solid grasp of them before moving on to more advanced topics.
