Subscript Seven (₇) is the Unicode character at U+2087 in the Subscripts and Superscripts block. It looks like a small lowered 7 and is common in math and science text such as x₇ or C₇.
Remember
Character ₇
Unicode U+2087
Hex entity ₇
Decimal ₇
CSS escape \2087
Named entity (none)
All of these produce the same glyph: ₇. Prefer the Unicode character (or its entities) when you need that exact glyph; use <sub>7</sub> when you want semantic subscript formatting instead.

How It Works
1. Hex:U+2087 → ₇ in HTML. The browser turns it into ₇.
2. Decimal: same code point as 8327 → ₇. Same result as hex.
3. CSS: use \2087 in content (not an HTML entity). #point::after appends that ₇ after the paragraph text.
4. Semantic <sub>:x<sub>7</sub> styles digit seven as a subscript. Prefer this when you need meaning, not a specific Unicode glyph.
Pitfalls & Tips
Common mistakes when working with Subscript Seven entities.
Named?
No named entity
HTML5 does not define &sub7; or similar. Use numeric forms.
CSS vs HTML
Do not mix escapes
\2087 belongs in CSS. ₇ / ₇ belong in HTML.
₇ vs 7 vs ⁷
Different characters
₇ is U+2087; digit 7 is U+0037; superscript ⁷ is U+2077.
Glyph vs tag
Choose intentionally
Use the Unicode glyph for exact look; use <sub> for semantic subscript on any text.
Semicolon
End references
Always finish with ; — write ₇, not ₇.
Fonts
Check the glyph
Some fonts draw ₇ weakly. If appearance matters, test the font or prefer <sub>.
