▶️ Final Section: Completion & Extension

🧠 Core Concepts List

By the end of this project, you should be able to explain and use these core ideas with confidence:

  • Build and apply @keyframes animations to real page elements.
  • Control animation behavior with timing, iteration count, direction, and fill mode.
  • Compare timing functions (ease-in-out, linear, steps()) and choose motion intentionally.
  • Combine multiple animations on one element using comma-separated shorthand values.
  • Use animation-play-state to pause/resume motion while keeping animation logic in CSS.
  • Structure animation demos with reusable HTML/CSS patterns and consistent class naming.
  • Understand that JavaScript in this project is a helper for replay/control, not the main learning target.
  • Apply animation in a realistic UI sequence using delay, stagger, and purposeful motion.
  • Use performance-friendly animation properties (transform, opacity) and respect reduced-motion needs.

🚧 Extensions

To earn full points, this project has one required extension path.

Required Extension (Only Option)

Build a simple front-end webpage inspired by the fake product-page example from Section 08.

  • Create frontend.html and frontend.css.
  • You are allowed to use the Section 08 fake front-end code as your starter, but you must make clear custom changes so the final extension is your own version.
  • Move all extension animation code into frontend.css (do not keep animation rules in <style> inside HTML).
  • Link your CSS file from frontend.html and make sure your page runs correctly.
  • Complete at least one clear animation sequence on your extension page (for example: entrance + stagger + feedback motion).
  • You may use Lorem ipsum placeholder text for content so you can focus on HTML structure, CSS styling, and animation.

Hints For Success

  1. Start by copying the final fake front-end structure into frontend.html.
  2. Move styling and @keyframes rules into frontend.css in organized blocks.
  3. Keep animation performance strong by mainly animating transform and opacity.
  4. Reuse the sequence pattern from Section 08: hero first, then CTA/card motion, then small feedback motion.
  5. Use short comments in your CSS to label each animation's purpose.

If you do not complete this required extension, the highest possible score is B (2.5/4).
