user-select:none Protection Lookup
Supported user-select semantics, no DRM or confidential-content protection. Explicit supplied computed/layout context only; not a browser cascade/layout engine or cross-browser guarantee.
Description
User-select controls ordinary selection behavior.
User-select controls ordinary selection behavior.1
Disabling selection does not protect the underlying source or prevent copying through other mechanisms. Use user-select:none Protection Lookup to look up a supported term.
When to use user-select:none Protection Lookup
Use user-select:none Protection Lookup to look up a supported term. Choose the exact supported token from the table; preserve its punctuation and capitalization.
How to use user-select:none Protection Lookup and understand its results
- Choose the exact supported token from the table; preserve its punctuation and capitalization.
- Enter User select 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 |
|---|---|---|---|
| userSelect | User select | string | Required; constraints below |
Enter one of the exact supported userSelect 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 |
|---|---|
| none | excludes user selection in its used-value context; does not protect source or prevent copying by other means |
| text | allows ordinary text selection |
| all | selection treats element content atomically |
| auto | used selection behavior depends on parent and element context |
| Output field | Meaning | Value type |
|---|---|---|
| meaning | Stored explanation for the exact supported token. | string |

}Limitations and assumptions
Disabling selection does not protect the underlying source or prevent copying through other mechanisms. 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.
