What You'll Learn

How to display the Down Right Diagonal Ellipsis (⋱) in HTML using hexadecimal, decimal, the named entity ⋱, and CSS escape methods. This character is U+22F1 (DOWN RIGHT DIAGONAL ELLIPSIS) in the Mathematical Operators block (U+2200–U+22FF)—a diagonal ellipsis oriented down and to the right, used in mathematical notation, typography, and design.

Render it with ⋱, ⋱, ⋱, or CSS escape \22F1. For vertical ellipsis use ⋮ (U+22EE). For quadruple down arrows use ⟱ (U+27F1).

🧠 How It Works

1

Hexadecimal Code

&#x22F1; uses the Unicode hexadecimal value 22F1 to display the Down Right Diagonal Ellipsis. The x prefix indicates hexadecimal format.

HTML markup
2

Decimal HTML Code

&#8945; uses the decimal Unicode value 8945 to display the same character.

HTML markup
3

Named HTML Entity

&dtdot; is the HTML5 named entity for U+22F1 (down right diagonal ellipsis). It is easy to read in source and resolves to ⋱.

HTML markup
4

CSS Entity

\22F1 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: ⋱. Unicode U+22F1. Vertical ellipsis: ⋮ (U+22EE). Serve HTML as UTF-8.

Use Cases

The Down Right Diagonal Ellipsis (⋱) is commonly used in:

∑ Math notation

Continued or diagonal patterns in matrices, series, and equations.

📜 Typography

Design layouts that need a down-right diagonal dot pattern.

📄 Technical docs

Indicate omitted diagonal entries or continuation in specifications.

📊 Tables and grids

Show skipped cells or trailing diagonal elements in data tables.

📖 Academic content

Papers and textbooks that use diagonal ellipsis notation.

💻 Symbol libraries

Math symbol pickers and design systems that include ⋱.

💡 Best Practices

Do

  • Use &dtdot; for readable markup, or &#x22F1; / &#8945;
  • Add aria-label when the symbol means continuation or omitted diagonal terms
  • Pair ⋱ with a legend in math or technical documents
  • Use \22F1 in CSS ::before / ::after for diagonal ellipsis icons
  • Serve pages with UTF-8 (<meta charset="utf-8">)

Don’t

  • Confuse &dtdot; (⋱, diagonal) with ⋮ (vertical ellipsis, U+22EE)
  • Confuse ⋱ with ⟱ (quadruple down arrow, U+27F1)
  • Put CSS escape \22F1 in HTML text nodes
  • Rely on the symbol alone in accessibility-critical UIs
  • Assume decorative fonts include all Mathematical Operators glyphs
