Module 6: Capstone Assessment & Final Review

Congratulations on completing the practical projects in Module 6! This final capstone assessment evaluates your mastery of advanced CSS layout systems, responsive design principles, modern selector features, and scalable design system architecture.

Technical Knowledge Review​

Part 1: Core Architectural Concepts​

1. Layout Engine Selection Matrix​

Choosing the right CSS layout engine is critical for writing clean, maintainable stylesheets.

RequirementBest ChoiceRationale
1D Directional FlowFlexboxIdeal for single-row or single-column alignments (e.g., navigation bars, action buttons).
2D Page Shell / App GridCSS Grid (grid-template-areas)Unifies rows and columns under explicit semantic region names.
Fluid Grid Item ScalingCSS Grid (auto-fit + minmax())Creates responsive multi-column layouts without manual media query breakpoints.
Overlapping LayersCSS Grid / Absolute PositionGrid allows multiple children to occupy the same grid area without taking elements out of normal flow.

2. Modern CSS Selectors & Features​

  • Parent & State Selection (:has()): Allows parent element styling based on child states (e.g., updating theme variables when a checkbox is checked).
  • Keyboard Focus Management (:focus-visible): Restricts focus indicators strictly to keyboard navigation (Tab), keeping mouse interactions clean.
  • Aspect Ratio Preservation (aspect-ratio): Replaces historic padding hacks with native aspect ratio enforcement.

Interactive Capstone Project Challenge​

In this final challenge, you will implement a Production Card & Modal Layout incorporating all Module 6 techniques: CSS Grid placement, custom property tokens, zero-JS state toggling using :has(), and responsive media query adaptations.

Final Self-Assessment Checklist​

Verify your readiness before moving on to advanced frameworks or real-world deployment:

  • Can build 2D Application layouts using grid-template-areas.
  • Understand the operational difference between auto-fit and auto-fill inside minmax() column rules.
  • Know how to structure design systems with modular CSS variables and BEM naming architecture.
  • Familiar with modern state-driven selectors like :has() and accessible focus rings via :focus-visible.
