So, you have decided to become a Web Developer, huh? When you’re just starting out with Web Development, it’s rather easy to get lost with the sheer amount of things there are to learn. Where should you start and, what should you focus on? In this post, I will share with you important concepts you should understand when starting out as well as resources to learn more. ## Foundations ### HTML, CSS and Javascript If it’s your very first time experimenting with Web Development, it’s important to start with the basics: learning what are HTML, CSS, and JavaScript, why we need all three, and how you can use them. - **HTML**, for _HyperText Markup Language,_ is the first pillar of every website, the skeleton. HTML tells the browser **what** there is on a page. So, it focuses on defining the content: titles, paragraphes, images, buttons, etc. It doesn’t bother with styles or interactions. - **CSS**, for Cascading Style Sheets, brings the content explicited in HTML to a whole new level, with styles ! With the skeleton metaphor, CSS adds the skin. It accesses elements defined in the HTML through tags, classes or IDs and say both **where they should go** and **what they should look like**. - Lastly, **Javascript (JS)** adds both the nerves and the muscles to bring interactions and behavior. It manipulates both CSS and HTML to define **what should happen based on what action** (whether from the User, the OS or the browser). That’s it! Those three are the foundations of the web and pretty much every website you have ever browsed in your life either use all three or a combination of the three. Here is a full example of a very basic web page mixing HTML, CSS and Javascript : ```html
