Entities are character sequences placed in the text of an HTML document to print out reserved characters which may otherwise be interpreted as HTML code by a browser, or other special characters that would be difficult to generate with a typical keyboard. In fact, using reference numbers, an entity can represent any Unicode character. When parsing the HTML, a browser replaces the entity’s character sequence with the character it represents.


Entities are case-sensitive and can take one of three forms.

The first form references an entity by name:


The second form references it by the decimal Unicode number:


The third represents it with the hexadecimal Unicode number, often with leading zeros:


So the copyright entity (©) can be represented as ©, &#169 or ©.

Entity Values

There are many HTML entities. The following are some common ones:

Entity Name 1st Form 2nd Form 3rd Form
Non-breaking space      
Less-than sign < &lt; &#60; &#x0003C;
Greater-than sign > &gt; &#62; &#x0003E;
Ampersand & &amp; &#38; &#x00026;
Quote " &quot; &#34; &#x00022;
Apostrophe ' &apos; &#39; &#x00027;
Copyright © &copy; &#169; &#x000A9;
Degree ° &deg; &#176; &#x000B0;
Euro &euro; &#8364; &#x020AC;
Bullet character &bullet; &#8226; &#x02022;

The Tab Entity

There is an entity &Tab; (or &#9;) which nominally produces a tab character. However, it will not behave as expected because HTML collapses whitespace where it appears in text with the exception of the non-breaking space entity, &nbsp;. So to render a tab in HTML text, it needs to be wrapped within a <pre> tag to preserve the whitespace.

<p>The tab entity &Tab; in this sentence is collapsed</p>
<p>The Tab entity &Tab; in this sentence is preserved</p>

Alternatively, four &nbsp; entities can be used.

<p>The Tab entity &Tab; in this sentence is collapsed.</p>
<p>The spaces &nbsp;&nbsp;&nbsp;&nbsp; in this sentence are preserved.</p>
