HTML (HyperText Markup Language) is the standard markup language used to create web pages. It provides the structure and content of websites by using a system of tags and attributes. HTML works alongside CSS for styling and JavaScript for interactivity to create complete web experiences.
CSS (Cascading Style Sheets) is used to style and layout web pages — for example, to alter the font, color, size, and spacing of your content, split it into multiple columns, or add animations and other decorative features. CSS enables the visual presentation and design of HTML documents.
JavaScript is a programming language that enables interactive web pages. It is an essential part of web applications and can be used both on the client-side and server-side. JavaScript allows you to implement complex features on web pages, such as displaying timely content updates, animated maps, and much more.
Each widget operates independently, allowing users to expand and collapse content as needed.
