overflow: visible is the default value for the overflow property. It allows content that exceeds the dimensions of a container to overflow and be fully visible outside the container.

Key Points

1
overflow: visible; – Excess content is not clipped and can spill outside the container.
2
No scrollbars are added, even if the content overflows.
3
Useful when you want overflowing content to remain visible, such as decorative elements or tooltips.

1
You have a div with a fixed height and its content sometimes exceeds that height. How would you use overflow: visible to ensure the extra content is still shown?
2
If you set overflow: visible on a container that has a border radius, what visual effect will you see on overflowing children?

We noticed a tooltip inside a scrollable panel is being cut off. Changing the panel's overflow to visible fixes it but introduces other issues. Walk me through the trade‑offs you’d consider.
2
During a redesign, a modal's backdrop was set to overflow: visible and caused the page behind to scroll unexpectedly. How would you debug and resolve this?

Our product page uses a CSS grid where some items need to spill over into adjacent cells for a decorative effect. How would you architect the CSS, including overflow settings, to support this at scale without breaking other components?
2
We have a component library that must support both left‑to‑right and right‑to‑left languages. How does overflow: visible interact with RTL layouts, and what patterns would you implement to avoid layout bugs?

We are migrating a legacy UI that heavily relies on overflow: visible for visual effects to a design system with strict accessibility and performance guidelines. What strategy would you propose to audit, refactor, or replace those usages across teams?
2
In a large SaaS platform, several micro‑frontends embed third‑party widgets that render outside their container bounds. How would you design a cross‑team policy for overflow handling that balances isolation, security, and visual fidelity?
