How It Works
1. Named:ª is the preferred HTML5 name for U+00AA → ª.
2. Hex:ª inserts the same code point. Same visual as named.
3. Decimal: same code point as 170 → ª.
4. CSS: use \00AA in content (not an HTML entity). #point::after appends ª.
5. Typed: paste ª in a UTF-8 document, or write ordinals like 1ª.
Pitfalls & Tips
Common mistakes when working with Feminine ordinal indicator.
Case
Named entity is case-sensitive
Use ª. &Ordf; is not a valid HTML5 named entity for this character.
º
Not masculine ordinal º
U+00BA (º, º) is for masculine ordinals (1º). Do not swap ordf and ordm.
°
Not the degree sign
U+00B0 (°) is for temperatures and angles. Ordinals use ª / º, not degree.
♀
Not the female sign
U+2640 (♀, ♀) is a gender symbol — not a linguistic ordinal marker.
Underline
Optional underline
Some locales underline ª/º in print. The Unicode character itself has no underline — add styling only if your design requires it.
CSS vs HTML
Do not mix escapes
\00AA belongs in CSS strings. ª / ª / ª belong in HTML.
a11y
Add accessible text
Screen readers may announce ª inconsistently. Prefer clear nearby wording when the ordinal is critical (for example “primera”).
Semicolon
End references
Always finish entities with ; — write ª, not ª.
