Expand/Collapse Widgets

HTML (HyperText Markup Language) is the standard markup language for creating web pages. It provides the structure and content of websites, allowing developers to organize information using semantic elements.

CSS (Cascading Style Sheets) is used to style and layout web pages. Key features include:

  • Selectors for targeting HTML elements
  • Properties for styling colors, fonts, and spacing
  • Responsive design with media queries
  • Animations and transitions
  • Flexbox and Grid layouts

JavaScript is a versatile programming language that enables interactive web experiences. It can manipulate the DOM, handle user events, make API requests, and much more.

This expand/collapse widget is built using JavaScript to demonstrate dynamic functionality and interactivity on web pages.
