- Uses home, book-club, journal, recipe, and responsive article-page layouts with 800px, 850px, and 500px values.
- What you can do after
- Apply it by editing a CSS value to constrain and tune a page’s readable content width.

The CSS max-width property sets an upper limit on an element's used width.
- How it is used
- Limits cards and page containers so responsive layouts do not become excessively wide.
- How deep it goes
- Works through concrete width and centering declarations without exploring CSS sizing internals.
- Examples
- Uses a 500px profile card, a 1200px newspaper body, and a 1280px checkout container.
- What you can do after
- Operate/configure it to keep an element flexible on narrow screens and capped on wide screens.
Math for Web Design
max-width is a CSS constraint that limits the maximum width of an element or container.
- How it is used
- Caps fluid layouts, flex items, text columns, and grid sidebars before excessive width harms fit or readability.
- How deep it goes
- Works through flex redistribution math, percentage liquid layouts, typography formulas, and auto-grid constraint behavior.
- Examples
- Uses a 960px page cap, a 220px flex-item cap, calculated article widths, and a 150px–300px grid sidebar.
- What you can do after
- Apply it via CSS to cap responsive containers and components while accounting for flex growth, grid sizing, or text readability.

- How it is used
- Constrains website containers and establishes outer edges for grid-based layout and content alignment.
- How deep it goes
