FAQ

Should settings forms always be multi-column on desktop?

Not always. Use multi-column only when it improves scanability without reducing clarity.

Is novalidate in the demo required?

No. It is optional for demo flow control. Real apps usually combine native validation and custom messaging.

Why keep labels visible if placeholders exist?

Placeholders are hints, not labels. Visible labels improve clarity and accessibility.

Should Save and Cancel always stay in one row?

On wide screens usually yes. On narrow screens, full-width stacked buttons are often more usable.

Can this pattern be reused for other setting types?

Yes. The section + field-grid + action-bar structure scales well for billing, privacy, and notification pages.
