Overflow and Clipping
Overflow occurs when content exceeds the available box. The overflow, overflow-x, and overflow-y properties control whether overflowing content is visible, clipped, or scrollable.
overflow: hidden is sometimes useful, but blindly hiding overflow can make content inaccessible. For scrollable regions, consider keyboard access and visible scroll affordances.
Overflow Behavior
Scrollable Content
.code-panel {
max-height: 400px;
overflow: auto;
overscroll-behavior: contain;
}💡 The content becomes scrollable once it exceeds the maximum height.
Key Takeaways
- Use overflow intentionally.
- Avoid hiding content that users need to access.
