What You'll Learn

How to display the Subset Above Right Arrow symbol (⥹) in HTML using hexadecimal, decimal, named entity, and CSS escape methods. This character is U+2979 (SUBSET ABOVE RIGHT ARROW) in the Supplemental Arrows-B block (U+2900–U+297F)—a combined subset-and-arrow symbol used in set theory and mathematical notation.

Render it with ⥹, ⥹, the named entity ⥹, or CSS escape \2979. It expresses subset relationships with directional implications, such as mappings or transformations between sets.

🧠 How It Works

1

Hexadecimal Code

&#x2979; uses the Unicode hexadecimal value 2979 to display the Subset Above Right Arrow symbol. The x prefix indicates hexadecimal format.

HTML markup
2

Decimal HTML Code

&#10617; uses the decimal Unicode value 10617 to display the same character. This is one of the most commonly used methods.

HTML markup
3

Named Entity

&subrarr; is the semantic named entity — the easiest to read in source HTML and the most self-descriptive option.

HTML markup
4

CSS Entity

\2979 is used in CSS stylesheets, particularly in the content property of pseudo-elements like ::before and ::after.

CSS stylesheet
=

Same visual result

All four methods produce the glyph: . Unicode U+2979 in the Supplemental Arrows-B block (U+2900–U+297F).

Use Cases

The Subset Above Right Arrow symbol (⥹) commonly appears in:

📐 Math Expressions

Equations with subset relationships and directional arrows.

🗃 Set Theory

Textbooks, papers, and lectures on sets and mappings.

📚 Academic Content

Research papers, proofs, and scholarly articles.

📄 Scientific Docs

Technical documentation and math web applications.

🎓 Education

Online courses and tutorials on mathematics and set theory.

💻 Math Software

Calculator interfaces and computational tool UIs.

📝 Research Papers

Conference proceedings and mathematical journals.

💡 Best Practices

Do

  • Use &subrarr; for readable source markup
  • Pick one style (hex / decimal / named) per project
  • Add aria-label for standalone symbols in math content
  • Test the glyph across browsers and fonts
  • Pair ⥹ with plain text on first use

Don’t

  • Mix entity styles randomly in one file
  • Assume all fonts render ⥹ correctly
  • Use CSS escape \2979 inside HTML text nodes
  • Use HTML entities in JS (use \u2979 instead)
  • Confuse ⥹ with plain subset (⊂) or arrow (→) alone

Key Takeaways

1

Three HTML references all render ⥹

&#x2979; &#10617; &subrarr;
2

For CSS stylesheets, use the escape in the content property

\2979
