Expand/Collapse Widgets

JavaScript is a high-level, interpreted programming language that conforms to the ECMAScript specification. It is a language that is also characterized as dynamic, weakly typed, prototype-based and multi-paradigm.

JavaScript is one of the core technologies of the World Wide Web, alongside HTML and CSS. It enables interactive web pages and is an essential part of web applications.

Modern web development includes several key features:

• Responsive Design: Websites that adapt to different screen sizes and devices
• Progressive Web Apps: Web applications that work offline and provide native-like experiences
• Single Page Applications: Apps that load a single HTML page and dynamically update content
• API Integration: Seamless connection with external services and data sources
• Performance Optimization: Fast loading times and smooth interactions

Expand/collapse widgets offer numerous advantages for web interfaces:

• Improved content organization and hierarchy
• Reduced visual clutter on the page
• Better user control over information display
• Enhanced mobile experience with limited screen space
• Faster page load times with progressive content disclosure

These widgets are particularly useful for FAQs, documentation, settings panels, and any content-heavy interfaces where information needs to be accessible but not overwhelming.

CSS provides powerful tools for creating smooth, performant animations without JavaScript. Transitions allow you to change property values smoothly over a specified duration.

Key concepts include:

• Transition properties: duration, timing function, delay
• Transform functions: translate, rotate, scale, skew
• Animation keyframes for complex sequences
• Hardware acceleration with transform and opacity
