writing-mode vertical-rl Orientation Lookup
Supported writing-mode axis orientation independent from inline text direction; not already existing logical-side conversion. Explicit supplied computed/layout context only; not a browser cascade/layout engine or cross-browser guarantee.
Description
Writing mode separates inline progression from block progression.
Writing mode separates inline progression from block progression.1
Vertical text changes the reference axes rather than merely rotating a horizontal layout. Use writing-mode vertical-rl Orientation Lookup to look up a supported term.
When to use writing-mode vertical-rl Orientation Lookup
Use writing-mode vertical-rl Orientation Lookup to look up a supported term. Choose the exact supported token from the table; preserve its punctuation and capitalization.
How to use writing-mode vertical-rl Orientation Lookup and understand its results
- Choose the exact supported token from the table; preserve its punctuation and capitalization.
- Enter Writing mode 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 |
|---|---|---|---|
| writingMode | Writing mode | string | Required; constraints below |
Enter one of the exact supported writingMode 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 |
|---|---|
| horizontal-tb | inline horizontal, block top-to-bottom |
| vertical-rl | inline vertical, block right-to-left |
| vertical-lr | inline vertical, block left-to-right |
| Output field | Meaning | Value type |
|---|---|---|
| meaning | Stored explanation for the exact supported token. | string |

}Limitations and assumptions
Vertical text changes the reference axes rather than merely rotating a horizontal layout. 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.

Use RTL Logical Layout Flip Check for a related task: A horizontal-writing RTL comparison can swap the expected physical left and right margins.
