How It Works
1. Hex:U+2172 → ⅲ in HTML. The browser turns it into ⅲ.
2. Decimal: same code point as 8562 → ⅲ. Same result as hex.
3. CSS: use \2172 in content (not an HTML entity). #point::after appends that ⅲ after the paragraph text.
4. Typed ⅲ: fine in UTF-8 pages. All four lines show the same roman numeral.
Pitfalls & Tips
Common mistakes when working with Lowercase Roman Numeral Three entities.
Named?
No named entity
HTML5 does not define &romaniii; or similar. Use numeric forms.
CSS vs HTML
Do not mix escapes
\2172 belongs in CSS. ⅲ / ⅲ belong in HTML.
ⅲ vs iii vs Ⅲ
Different characters
ⅲ is U+2172; letters iii are Basic Latin; uppercase Ⅲ is U+2162.
Fonts
Check the glyph
Number Forms support varies by font. If ⅲ is missing, fall back to iii or another font.
Semicolon
End references
Always finish with ; — write ⅲ, not ⅲ.
Lists
CSS list-style
For auto-numbered roman lists, prefer list-style-type: lower-roman instead of hard-coding ⅲ.
