The behavior works; now improve its presentation.
The previous chapter pages repeat the doctype, head, and sometimes navigation. This works, but makes every change riskier. We will share common HTML and give CSS, images, and optional JavaScript clear locations.
A view does three things
Structure
Headings, lists, forms, and links in semantic HTML.
Display
Values supplied by the controller, always escaped.
Composition
Assembly of small shared partials.
References
Links to public styles, images, and scripts.
A view does not decide everything
IN THE VIEW
Loop through books, escape a title, choose an HTML element, display an already prepared error.
OUTSIDE THE VIEW
Query a database, modify the session, decide permissions, or validate a business rule.

What to remember
- The controller prepares; the view presents.
- A partial prevents copying shared HTML.
- Private views stay in src/views.
- Files requested directly by the browser go in public.
