How It Works
1. Hex:⅐ inserts code point U+2150 → ⅐.
2. Decimal: same code point as 8528 → ⅐. Same visual as hex.
3. CSS: use \2150 in content (not an HTML entity). #point::after appends ⅐.
4. Typed: paste ⅐ in a UTF-8 document when you need the one-seventh glyph as one character.
Pitfalls & Tips
Common mistakes when working with fraction 1 by 7.
Name
No named entity
There is no HTML5 named entity for U+2150. Use ⅐ or ⅐. Do not invent &frac17;.
1/7
Not three characters
Typing 1/7 creates three code points. ⅐ is one Number Forms character.
Neighbors
Not 1/6 or 1/8
One sixth is ⅙ (⅙). One eighth is ⅛. Match the code point your source requires.
Font
Font coverage
Some fonts omit rare vulgar fractions. If ⅐ is missing, fall back to 1/7 or a font with Number Forms coverage.
CSS vs HTML
Do not mix escapes
\2150 belongs in CSS strings. ⅐ / ⅐ belong in HTML.
a11y
Add accessible text
Screen readers may not announce ⅐ clearly. Prefer aria-label="one seventh" or nearby prose when the fraction carries meaning.
Semicolon
End references
Always finish entities with ; — write ⅐, not ⅐.
