HTML Entities

Some characters are reserver in html.

If you use the less than (<) or greater than (&gt) 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: &lt; or &#60;

Advantages of using an entity name: An entity name is easy to remember.

Disadvantages of using an entity name: Browsers may not support all entity names, but the support for entity numbers is good.

Combining 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 (encodin) used int the page.

Here are some examples:

Mark	Character	Constants	Result
̀	a	à	a&#768
́	a	á	á
̂	a	â	â
̃	a	ã	ã
̀	O	Ó	Õ
́	O	Ó	Ó
̂	O	Ô	Ô
̃	O	Õ	Õ
