Using Named Entity: ♭
Using Hex Code: ♭
Using HTML Code: ♭
Using CSS Entity: ♭
Key: B♭ major
How It Works
1. Named:♭ is the clearest HTML form and renders ♭.
2. Hex:U+266D → ♭ in HTML. Same result as the named entity.
3. Decimal: same code point as 9837 → ♭. Same result as hex and named.
4. CSS: use \266D in content (not an HTML entity). #point::after appends that ♭ after the paragraph text.
Pitfalls & Tips
Common mistakes when working with the Music Flat Sign.
Prefer
Use ♭
The named form is clearer than numeric references and is defined in HTML5.
vs b
Not the letter b
Letter b is ASCII. Prefer ♭ for proper music accidentals in typography.
vs ♯
Not sharp
♯ raises pitch. ♭ lowers pitch. Do not swap them.
CSS vs HTML
Do not mix escapes
\266D belongs in CSS. ♭ / ♭ / ♭ belong in HTML.
Encoding
Declare UTF-8
If you type ♭ directly, keep <meta charset="UTF-8"> so the file is not misread.
Semicolon
End references
Always finish with ; — write ♭, not &flat.
