Built with Hex: ⇟
Built with Decimal: ⇟
Built with CSS: ⇟
Typed: ⇟
Label: Page Down ⇟
How It Works
1. Hex:⇟ inserts code point U+21DF → ⇟.
2. Decimal: same code point as 8671 → ⇟. Same visual as hex.
3. CSS: use \21DF in content (not an HTML entity). #point::after appends ⇟.
4. Typed: paste ⇟ in a UTF-8 document, or pair it with a label.
Pitfalls & Tips
Common mistakes when working with Down Arrow With Double Stroke.
Name
No named entity
There is no HTML5 named entity for U+21DF. Use ⇟ or ⇟.
↓
Not ↓
↓ is the plain down arrow (U+2193). U+21DF has a double horizontal stroke through the shaft.
⇞
Not the up form
U+21DE is the up arrow with double stroke. Keep the two code points distinct.
CSS vs HTML
Do not mix escapes
\21DF belongs in CSS strings. ⇟ / ⇟ belong in HTML.
Fonts
Arrow font coverage
Some fonts draw rare stroked arrows poorly. Prefer a font with solid Arrows block support.

Add accessible text
A lone Page Down glyph can be unclear to screen readers. Pair it with visible text or an aria-label.
Semicolon
End references
Always finish numeric entities with ; — write ⇟, not ⇟.
