Task 4 – jQuery UI

HTML, or HyperText Markup Language, serves as the foundation for creating web pages and web applications. It uses a system of tags and elements to structure content so that browsers can display it correctly. The purpose of HTML is to describe the meaning and structure of web content.

CSS, or Cascading Style Sheets, is a stylesheet language used to control the presentation and layout of web pages. While HTML provides the structure and content of a webpage, CSS determines how that content looks, including colours, fonts, spacing, and positioning. This separation of structure (HTML) and style (CSS) makes web development more organised and flexible.

JavaScript is a powerful and versatile programming language primarily used to create dynamic and interactive content on websites. It’s often abbreviated as JS and is a key component of the web development triad alongside HTML (structure) and CSS (style). JavaScript brings functionality and interactivity to web pages, enabling features like animations, form validation, dynamic updates, and much more.

jQuery is a fast, small, and feature-rich JavaScript library that simplifies HTML document traversal, event handling, animation, and AJAX (Asynchronous JavaScript and XML) interactions. It is designed to make writing JavaScript easier and more concise, particularly when dealing with DOM manipulation and cross-browser compatibility.
