HTML Entities

Some characters are reserved in HTML.

If you use the less than (<) or greater than (>) signs in your text, the browser might mix them with tags.

Character entities are used to display reserved characters in HTML.

A character entity looks like this:

&entity_name;
OR
&#entity_number;

To display a less than sign (<) we must write: < or <

Non-breaking Space

A common character entity used in HTML is the non-breaking space:  

A non-breaking space is a space that will not break into a new line.

Two words separated by a non-breaking space will stick together (like 10 km/h, 10 PM).

Diacritical Marks

A diacritical mark is a "glyph" added to a letter.

Some diacritical marks, like grave ( ` ) and acute ( ´ ) are called accents.

Diacritical marks can appear both above and below a letter, inside a letter, and between two letters.

Diacritical marks can be used in combination with alphanumeric characters, to produce a character that is not present in the character set (encoding) used in the page.
