What You'll Learn

How to display the Up Right Diagonal Ellipsis (⋰) in HTML using hexadecimal, decimal, the named entity ⋰, and CSS escape methods. This character is U+22F0 (UP RIGHT DIAGONAL ELLIPSIS) in the Mathematical Operators block (U+2200–U+22FF)—three dots arranged diagonally up and to the right, indicating continuation or omission in matrix and set notation.

Render it with ⋰, ⋰, ⋰, or CSS escape \22F0. Compare ⋱ (U+22F1, down right diagonal ellipsis via ⋱) and ⋯ (U+22EF, midline horizontal ellipsis via &cdots;).

🧠 How It Works

1

Hexadecimal Code

&#x22F0; uses the Unicode hexadecimal value 22F0 to display the Up Right Diagonal Ellipsis. The x prefix indicates hexadecimal format.

HTML markup
2

Decimal HTML Code

&#8944; uses the decimal Unicode value 8944 to display the same character.

HTML markup
3

Named HTML Entity

&utdot; is the HTML5 named entity for U+22F0 (up right diagonal ellipsis). It is easy to read in source and resolves to ⋰.

HTML markup
4

CSS Entity

\22F0 is used in CSS stylesheets in the content property of pseudo-elements like ::before and ::after.

CSS stylesheet
=

Same visual result

All four methods produce: . Unicode U+22F0 in the Mathematical Operators block (U+2200–U+22FF). Diagonal dots indicating continuation up and to the right in matrices and sets.

Use Cases

The Up Right Diagonal Ellipsis (⋰) is commonly used in:

🔢 Mathematical expressions

Equations and formulas with diagonal continuation patterns.

📜 Set theory

Set notation and proofs requiring diagonal ellipsis.

📊 Matrix notation

Matrix corners and array structures with omitted elements.

📚 Academic papers

Research documents and scholarly publications with math notation.

🛠 Technical documentation

Programming and math docs with structured continuation symbols.

🗺 Mathematical diagrams

Visual representations showing diagonal continuation or omission.

💡 Best Practices

Do

  • Use &utdot; for readable math markup when supported
  • Use &#x22F0; or &#8944; consistently in documents
  • Pair with proper subscripts in matrix notation (e.g. a11 ⋰ ann)
  • Use \22F0 in CSS ::before / ::after for generated content
  • Serve pages with UTF-8 (<meta charset="utf-8">)

Don’t

  • Use U+022F0—the correct value is U+22F0 with CSS \22F0
  • Confuse ⋰ (up-right, U+22F0) with ⋱ (down-right, U+22F1, &dtdot;)
  • Use three periods ... when diagonal ellipsis notation is required
  • Put CSS escape \22F0 in HTML text nodes
  • Assume all decorative fonts include Mathematical Operators glyphs

Key Takeaways

1

Named entity: &utdot;

&#x22F0; &#8944;
2

For CSS stylesheets, use \22F0 in content
