CSS Transitions Lab - Week 2

⚡ Transform static interfaces into smooth, interactive experiences!

Overview

Welcome to your journey into CSS transitions! This comprehensive lab will teach you how professional websites create those smooth, polished interactions that make users feel delighted rather than jarred by sudden changes.

This lab is designed as a progressive learning experience with 7 hands-on playgrounds that build from basic concepts to advanced interaction patterns. You'll master the transition property while practicing with state selectors, timing functions, and various CSS properties.

What You'll Learn

• CSS Transition Fundamentals: Property syntax, timing, and best practices
• State Selectors: :hover, :active, :focus and when to use each
• Transform Functions: translate, scale, rotate for dynamic effects
• Timing Functions: Natural motion with ease, ease-in-out, and more
• Professional Patterns: Real-world interaction design techniques
• Performance Considerations: Smooth animations that don't impact user experience
