A user interface must follow specific rules for layout and interaction.
These rules ensure a consistent and usable experience. They define how elements like grids, cards, and buttons behave.
A grid layout uses `display:grid` and `grid-template-columns:minmax(0,1fr)`. It sets a `gap:16px` between items. This creates a flexible column structure. Filter chips should wrap to the next line. Use `flex-wrap:wrap` and `gap:8px` for spacing. This keeps the layout clean. Cards must fit their container. Set `max-width:100%` and `overflow-wrap:anywhere`. This prevents content from breaking the layout. Tap targets, like buttons, must be at least 44x44 pixels. This makes them easy for a user to press. A sticky footer stays at the bottom of the screen. It uses `position:sticky` and `bottom:0`. Add `padding:12px 16px` for spacing. Submit buttons should fit their content. Use `flex:0 0 auto` and `padding:12px 24px`. This makes the button size correct. A timer pill should have stable numbers. Use `font-variant-numeric: tabular-nums`. This stops numbers from moving around. The interface must not have horizontal scrolling. This applies at all screen widths. A user should only scroll vertically.
A developer is building a new web page. The developer ensures all buttons are at least 44x44 pixels. This makes the buttons easy for a user to tap on a mobile phone.

A developer must prevent horizontal scrolling on mobile. Use `max-width: 100%; overflow-x: hidden;` for the main page elements.
A developer should always start designing for mobile phones. The page must fit a 320-pixel screen width without horizontal scrolling.
A design system is a set of rules for creating web pages. These rules tell a developer how to use fonts and text sizes.
A panel is a box that holds text on a screen. The text in a panel should be very short or quite long.
