To build this feature (often project #45 or #50 in a 60-project series), you need: Using CSS Grid

CSS3 plays a psychological role in security. A user trusts an interface that feels responsive and transparent. Using CSS Grid, a developer can build a "Security Dashboard" that shows the SHA-256 hash of each chunk updating in real-time. When a user sees the checksum visually match (via a green box-shadow glow), they trust the transfer. Furthermore, CSS backdrop-filter and position: sticky ensure that the encryption status bar is always visible, reassuring the user that the data never leaves their machine in plaintext.

Crucially, vanilla JavaScript forces the developer to handle backpressure and concurrency manually. Without React’s virtual DOM or Angular’s dependency injection, the coder learns exactly how requestAnimationFrame updates the UI during a hash computation, and how setTimeout prevents the main thread from freezing. This low-level knowledge is the prerequisite for secure transfers; you cannot secure what you do not understand.
