Sizing Utilities

Sizing Utilities

Sizing utilities provide common width and height values and help components adapt without custom CSS declarations.

Core concept

Explain width and height percentage utilities, viewport sizing, min/max constraints, and the difference between setting a size and allowing content to determine its natural size.

Using it in a real interface

Use a responsive image, a full-height panel, and a constrained content region to demonstrate different sizing goals. Explain why max-width:100% is important for media that should not overflow its container.

Implementation notes

Avoid fixed heights for text-heavy content. A component that works with short placeholder text may break when real content wraps to several lines.
