A mobile application must fit the screen without horizontal scrolling.
Content must wrap and adjust to different screen sizes. Hardcoded sizes and inline styles can cause display problems on mobile devices.
A developer must prevent horizontal scrolling on mobile. Use `max-width: 100%; overflow-x: hidden;` for the main page elements. This ensures content stays within the screen width. Avoid setting fixed minimum heights on elements like cards. Let flexible layout systems handle sizing. This allows elements to adjust naturally to different screen sizes. Use `100dvh` instead of `100vh` for viewport height. `100dvh` correctly accounts for mobile browser toolbars. This prevents content from being hidden behind browser elements. Remove inline styles from HTML. Move all styling to CSS classes. Inline styles are difficult to manage and can cause unexpected layout issues on mobile. Apply `max-width: 100vw; overflow: hidden;` to main containers and headers. This helps manage overall layout and prevents content from spilling out. Ensure long text wraps correctly. Use `word-break: break-word;` when necessary. This prevents text from overflowing its container. Reduce unnecessary padding and margins on mobile. Whitespace takes up valuable screen space. Optimize spacing for smaller screens.
A developer creates a product page. The developer uses `min-height: 300px` for product cards. On a small mobile phone, the cards are too tall and push other content off the screen. The developer should remove `min-height` and let the content define the card height.

A grid layout uses `display:grid` and `grid-template-columns:minmax(0,1fr)`. It sets a `gap:16px` between items.
A developer must plan mobile layouts separately from desktop layouts. Decide which controls collapse or hide.
Realistic diagrams often have parts that overlap. For example, a bicycle bell sits on a handlebar.
The user interface for Chapter 1 is the master design. All other chapters must use this design.
