overscroll-behavior Scroll-Chaining Stop
Supported overscroll behavior semantics on scroll containers, not disable all browser gestures or active scrolling. Explicit supplied computed/layout context only; not a browser cascade/layout engine or cross-browser guarantee.
Description
Overscroll behavior concerns scroll chaining and boundary effects.
Overscroll behavior concerns scroll chaining and boundary effects.1
A keyword lookup does not run a scrolling interaction or modify the document. Use overscroll-behavior Scroll-Chaining Stop to look up a supported term.
When to use overscroll-behavior Scroll-Chaining Stop
Use overscroll-behavior Scroll-Chaining Stop to look up a supported term. Choose the exact supported token from the table; preserve its punctuation and capitalization.
How to use overscroll-behavior Scroll-Chaining Stop and understand its results
- Choose the exact supported token from the table; preserve its punctuation and capitalization.
- Enter Overscroll behavior using the field table and validation rules below, then run the tool.
- Read Meaning and interpret units, signs, ordering and placeholders as explained below.
- If the tool reports an input error, correct that field and rerun. A successful false result, empty match list or unknown-evidence placeholder has the specific meaning described here; check the limitations before applying the result.
| Input field | Meaning | Value type | Requirement |
|---|---|---|---|
| overscrollBehavior | Overscroll behavior | string | Required; constraints below |
Enter one of the exact supported overscrollBehavior tokens in the table below. The implementation performs a case-sensitive lookup and returns the stored meaning without interpreting a stylesheet, audio recording or performance. Unsupported tokens, added whitespace and alternate capitalization are input errors. The entries describe a bounded vocabulary rather than every valid value in the wider topic.
meaning = storedTable[exactSupportedToken] Field order, units and branch conditions follow the implementation explanation above.
| Exact supported token | Stored meaning |
|---|---|
| auto | permits default scroll chaining and boundary effects |
| contain | suppresses scroll chaining, permits local boundary effects |
| none | suppresses scroll chaining and default boundary effects |
| Output field | Meaning | Value type |
|---|---|---|
| meaning | Stored explanation for the exact supported token. | string |

}Limitations and assumptions
A keyword lookup does not run a scrolling interaction or modify the document. Apply the exact scope and assumptions described above.
All listed fields require explicit values. Unexpected fields, incorrect types, nonfinite numbers and sparse arrays fail validation. Domain-specific bounds, alignments and supported tokens are stated above; extremely large inputs or outputs can also be rejected. These errors differ from successful results such as false, no matches or unknown evidence.
