In the past, we learned about the wire that connects client computers with server computers and what occurs when the server discovers the appropriate source. Afterward, the information that the server provides typically includes three kinds of files: HTML, CSS, and JavaScript. They play a crucial role in how websites function. Nevertheless, it may still be unclear what these files accomplish and why many diverse file types exist.

Note

Three main components of any website: HTML, CSS, JavaScript

The HTML code file is an essential component of any website as it is responsible for the content that appears on the webpage. In analogy, if a website were a house, the HTML would be the bricks used to build the structure. It is the raw material that makes up the website's content, such as text, images, buttons, or links.

The CSS files are the second type of file that plays a crucial role in styling your website. They determine the look and feel of your website, just like how the color of the walls or the shape of the door can affect the overall appearance of a house. CSS files target all the content created using HTML and apply styling to those elements. You can use CSS to make a button red and have rounded corners and the button text to have a particular font.

The final component, JavaScript code is what adds functionality to a website. In analogy, it's like adding light bulbs or a cooker to a house to turn it into a home. JavaScript transforms a static website that displays only images or text into a dynamic website that a user can interact with.
