HTML Entity for Contains Long Horizontal Stroke (⋺)
What You'll Learn
How to display Contains Long Horizontal Stroke (⋺) in HTML using numeric references, the named entity, and CSS escapes. This character is U+22FA (CONTAINS WITH LONG HORIZONTAL STROKE) in the Mathematical Operators block (U+2200–U+22FF). It is used in set theory for the “contains with long horizontal stroke” relation.
Use the named entity ⋺, hex ⋺, decimal ⋺, or CSS \22FA. ⋺ is the most readable option when writing HTML by hand. Do not confuse ⋺ with Contains As Member U+220B (∋) or Contains As Member Small U+220D (∍).

Use Cases
Contains Long Horizontal Stroke (⋺) commonly appears in:
Specialized “contains with long horizontal stroke” relations in formal notation.
Advanced discrete math and logic course materials.
Technical PDFs and HTML preprints with set-relation operators.
Symbol glossaries and character reference tables for math HTML.
Examples showing ⋺ alongside numeric references.
Tools rendering math symbols without full MathML.
Describe the relation in text; do not rely on the glyph alone.
💡 Best Practices
Do
- Prefer
⋺for readable hand-written HTML - Use math fonts (Cambria Math, STIX Two Math) for clear operators
- Keep entity style consistent across a document
- Use
\22FAonly inside CSScontent - Distinguish ⋺ from simpler contains operators (∋, ∍)
Don’t
- Write U+022FA—the correct notation is U+22FA
- Substitute ∋ when the long-stroke operator is required
- Use CSS
\022FAwith a leading zero unless your toolchain requires it—prefer\22FA - Put CSS escape in HTML text nodes
- Mix entity styles randomly in one file
