This demo showcases a real app with an interactive playground containing a card component built with nested styles and rem units, demonstrating how to structure complex layouts in a clean and maintainable way.

What to try

• Use the buttons to interact with the card component in the playground tab
• Modify the padding and margin values in the style definitions to see how spacing affects the layout
• Change colors in the style definitions to customize the card appearance
• Adjust font sizes to see how rem units scale proportionally
• Explore the nested style structure to understand how hierarchy improves organization
