HTML Symbols

Understand the topic

Symbols can be written directly as Unicode characters or through numeric and named character references. The correct choice depends on encoding, readability, and available fonts. A symbol alone may be unclear to readers or assistive technology, so pair it with words when it communicates an action, quantity, or status. Technical notation may need more structure than a decorative symbol.

Worked example

<p>Temperature: 28 &deg;C</p>
<p>Price: &euro;12</p>
<p>Approved: &#10003; application accepted</p>

The degree, euro, and check symbols each have surrounding context. The status does not rely on a check mark alone.

Practice

Write a temperature of 30 degrees Celsius using a character reference.

<p>30 &deg;C</p>

Common mistake

Do not assume every font contains every Unicode character. Check the actual rendered text on your target devices.
