HTML/CSS/JAVA

HTML, CSS, and JavaScript are the core technologies for building web pages and web applications.

1. HTML (Hypertext Markup Language): HTML is the standard markup language used to create web pages. It structures web content through elements such as headings, paragraphs, links, and images. Each element is denoted by tags, like <h1> for a main heading or <p> for a paragraph. HTML5, the latest version, introduces new elements and attributes that allow for more diverse and efficient web design and application development.

2. CSS (Cascading Style Sheets): CSS is a stylesheet language used to describe the presentation of a document written in HTML. It allows web developers to control layout, colors, fonts, and more, thus separating content (HTML) from design. The "cascading" aspect refers to the way CSS rules cascade down from multiple sources, with a defined priority scheme to resolve conflicts. CSS3, the latest version, brings new capabilities like animations, transitions, and responsive design.

3. JavaScript: JavaScript is a high-level, interpreted scripting language that enables interactive web pages. Unlike HTML and CSS, which are markup and style languages respectively, JavaScript is a true programming language that can manipulate HTML elements and CSS styles. It's used for client-side scripting to implement features like form validation, dynamic content updates (AJAX), and complex user interfaces. Modern JavaScript has evolved with the introduction of frameworks and libraries like React, Angular, and Vue.js, enhancing the development of complex web applications.

Each of these technologies plays a unique and crucial role in web development. HTML provides structure, CSS adds styling, and JavaScript introduces interactivity and logic.
