How It Works
1. Hex:U+2215 → ∕ in HTML. Preferred when there is no named entity.
2. Decimal: same code point as 8725 → ∕. Same glyph as hex.
3. CSS: use \2215 in content (not an HTML entity). #point::after appends that ∕ after the paragraph text.
4. Typed: paste ∕ in UTF-8 when the page is encoded as UTF-8.
5. Fraction / ratio: write 1∕2 or 16∕9 for inline fraction-style notation.
Pitfalls & Tips
Common mistakes when working with Division Slash.
Name
No named entity
There is no &divisionslash;. Use ∕ or ∕.
/
Not the solidus
Use / for URLs and paths. For math division slash, use ∕.
÷
Not the division sign
÷ (÷) is the arithmetic obelus. Different from U+2215.
⁄
Not fraction slash
⁄ (⁄, U+2044) is a related but separate character for fractions.
CSS vs HTML
Do not mix escapes
\2215 belongs in CSS strings. ∕ / ∕ belong in HTML.
Semicolon
End references
Always finish with ; — write ∕, not ∕.
