This lesson

This lesson teaches CSS Shadows—the ideas, syntax, and habits you need before moving on in CSS.

Without a solid grasp of CSS Shadows, you will repeat mistakes in CSS exercises and on real pages or scripts.

You will apply CSS Shadows in contexts like: All browser UIs, component libraries, marketing sites, and many native apps that reuse web views.

Read the lesson, edit HTML/CSS in the playground, press Run to preview, then answer the lesson MCQs.

When intermediate lessons feel comfortable and you are ready for production-style trade-offs.

Shadows add depth cues and hierarchy. Use restraint to avoid muddy, over-designed interfaces.

Heavy multi-layer shadows on many elements can increase paint cost and visual noise.

Q: Box-shadow vs drop-shadow filter?
A: Box-shadow follows box shape; filter drop-shadow follows alpha silhouette.
Q: Why use elevation tokens?
A: Predictable hierarchy and easier theme tuning.
Q: Common card shadow mistake?
A: Same heavy shadow everywhere, removing hierarchy meaning.

Practice: Change one property in the playground and observe cascade + layout in DevTools.

Can you explain this lesson in 30 seconds without reading notes?
