HTML Entity for Parallel To (∥)
What You'll Learn
How to display the Parallel To symbol (∥) in HTML using hexadecimal, decimal, named entity, and CSS escape methods. This character is U+2225 (PARALLEL TO) in the Mathematical Operators block (U+2200–U+22FF)—used for parallel lines in geometry, vector relations, and mathematical notation.
Render it with ∥, ∥, the named entity ∥, or CSS escape \2225. Do not confuse ∥ with U+2016 (‖, double vertical line, ‖) or with the ASCII pipe |.

A simple example showing ∥ using hexadecimal code, decimal HTML code, the named entity, and a CSS content escape:
<!DOCTYPE html>
<html>
<head>
<style>
#point::after{
content: "\2225";
}
</style>
</head>
<body>
<p>Parallel to (hex): ∥</p>
<p>Parallel to (decimal): ∥</p>
<p>Parallel to (named): ∥</p>
<p>Line AB ∥ CD</p>
<p id="point">Parallel to (CSS): </p>

🧠 How It Works
Hexadecimal Code
∥ uses the Unicode hexadecimal value 2225 to display the parallel to symbol.
Decimal HTML Code
∥ uses the decimal Unicode value 8741 for the same character.
Named Entity
∥ is the standard HTML named entity for U+2225—readable and widely supported.
CSS Entity
\2225 is used in CSS stylesheets in the content property of pseudo-elements for decorative markers.
Parallel result
All four methods render ∥. Unicode U+2225 in Mathematical Operators. Next: Partial Difference (∂).
Use Cases
The Parallel To symbol (∥) is commonly used in:
Parallel lines and segments (e.g. AB ∥ CD) in educational content.
Parallel vector relations in linear algebra and physics.
Online courses, homework help, and reference pages.
Technical documentation with geometric and spatial notation.
Character pickers, entity documentation, and math symbol guides.
Pair ∥ with visible text or MathML for complex formulas when possible.
💡 Best Practices
Do
- Use
∥when readability matters in HTML source - Use
∥or∥in numeric-only contexts - Set
<meta charset="utf-8">for reliable rendering - Use ∥ for parallel relations, not the ASCII pipe
| - Pick one reference style per project for consistency
Don’t
- Confuse ∥ (parallel to) with ‖ (double vertical line,
‖) - Use padded Unicode notation like U+02225—the correct value is
U+2225 - Use CSS escape
\2225in HTML text nodes - Substitute ASCII
||or|for proper math notation - Assume every font renders Mathematical Operators identically—test your typeface
