What is HTML CSS and Javascript?

As a domain expert in web technologies, I can explain the core components of web development: HTML, CSS, and JavaScript. HTML (Hypertext Markup Language) is the backbone of any website. It provides the basic structure of the site, allowing you to create elements such as headings, paragraphs, links, and images. HTML is like the skeleton of a body—it defines what the page is made of. CSS (Cascading Style Sheets) is used to control the presentation of the HTML elements. It deals with the formatting and layout of the content. CSS allows you to change the color, font, spacing, and overall design of the site, making it more visually appealing. Think of CSS as the clothing and makeup for the HTML structure—it makes the content look good. JavaScript is a scripting language that enables you to control the behavior of different elements on a webpage. It can manipulate the HTML and CSS to create dynamic and interactive features. For example, JavaScript can be used to validate forms, create animations, handle events, and even make asynchronous requests to the server without reloading the page. JavaScript is like the nervous system—it controls how the page responds to user interactions.

An overview: HTML provides the basic structure of sites, which is enhanced and modified by other technologies like CSS and JavaScript. CSS is used to control presentation, formatting, and layout. JavaScript is used to control the behavior of different elements.
