HTML Entity for Image Of Or Approximately Equal To (≓)
What You'll Learn
How to display the Image Of Or Approximately Equal To symbol (≓) in HTML using hexadecimal, decimal, and CSS escape methods. This relation combines “image of” (e.g., under a function) with “approximately equal to” in mathematical notation.
This character is U+2253 (IMAGE OF OR APPROXIMATELY EQUAL TO) in the Mathematical Operators block (U+2200–U+22FF). Use ≓, ≓, or CSS \2253. There is no named HTML entity—use numeric codes or CSS.

🧠 How It Works
Hexadecimal Code
≓ uses Unicode hexadecimal 2253 to display ≓ in HTML markup.
Decimal HTML Code
≓ uses decimal Unicode value 8787 for the same character.
CSS Entity
\2253 (or \02253) is used in CSS, typically in the content property of pseudo-elements such as ::after.
Same visual result
All three methods produce ≓. Unicode U+2253 is in Mathematical Operators. No named entity—use hex, decimal, or CSS. Next: Increment.

💡 Best Practices
Do
- Use
≓or≓in HTML (no named entity) - Keep one numeric method (hex or decimal) consistent per document
- Provide context (e.g. “image of A under f ≓ B”) in mixed content
- Use
aria-labelor surrounding text for accessibility on standalone symbols - Declare UTF-8 with
<meta charset="utf-8"> - Test rendering across browsers and math-friendly fonts
Don’t
- Expect a named HTML entity for U+2253
- Put CSS escape
\2253in HTML text nodes - Confuse ≓ with ⊷ (image of), ≈ (approximately equal), or ≒ (approximately equal to or the image of)
- Mix hex and decimal styles randomly in one file
- Assume every font renders U+2253 clearly
