HTML Entity for Bullet Operator (∙)
What You'll Learn
How to display the Bullet Operator (∙) in HTML using numeric references and CSS escapes. This character is U+2219 in the Mathematical Operators block (U+2200–U+22FF), approved in Unicode 1.1 (1993). In math it denotes the dot product or scalar multiplication; it appears as a small middle dot.
There is no named HTML entity for U+2219. Use ∙, ∙, or \2219 in CSS content. For the classic list bullet, use U+2022 (•) with • instead. Related: Middle Dot (·, U+00B7, ·).

Hexadecimal Code
∙ uses the Unicode hexadecimal value 2219 to display the Bullet Operator. The x prefix indicates hexadecimal format.
Decimal HTML Code
∙ uses the decimal Unicode value 8729 to display the same character. Commonly used for Mathematical Operators symbols.
CSS Entity
\2219 is the CSS escape for U+2219, used in the content property of ::before or ::after (e.g. custom list markers).
Same visual result
All three methods produce the Bullet Operator glyph: ∙. Unicode U+2219 sits in the Mathematical Operators block (U+2200–U+22FF). For list bullets use • (U+2022 •).
Use Cases
The Bullet Operator (∙) commonly appears in the following scenarios:
Dot product in linear algebra, scalar multiplication, and algebraic expressions.
Physics and engineering docs showing inner products and vector operations.
Math tutorials, science content, and university coursework materials.
API specs, scientific papers, and formatted technical documentation.
Middle-dot style custom list markers via CSS ::before.
Navigation indicators and subtle dot separators in interface copy.
When used as list markers, pair with <ul>/<li> semantics.
💡 Best Practices
Do
- Use
∙or∙consistently in markup - Use
•(•) for standard unordered list bullets - Use math-friendly fonts for reliable operator rendering
- Apply
\2219in CSScontentfor custom markers - Declare
<meta charset="utf-8">in HTML documents
Don’t
- Confuse ∙ (U+2219, math operator) with • (U+2022, list bullet)
- Expect a named HTML entity—none exists for U+2219
- Use CSS escape
\2219inside HTML text nodes - Replace semantic
<ul>lists with bare dot characters - Mix entity styles randomly in one file
