Tailwind CSS's hero animation — simulated code-typing sequence, decoded
A technical hero demonstration featuring a simulated code-typing sequence that drives real-time reactive layout and style updates on a component preview card.
The animation centers on a developer experience walkthrough where a blue cursor navigates a dark code editor. As utility classes like 'p-7' and 'rounded-md' are added, the preview card on the right instantly reacts—its internal padding expands and its featured image corners soften, creating a snappy, synchronized rhythm of code-to-visual feedback.
