HTMLEntities


Reserved characters in HTML must be replaced with entities:

  • < (less than) =&lt;
  • > (greater than) =&gt;

HTML Character Entities

Some characters are reserved in HTML.

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

Entity names or entity numbers can be used to display reserved HTML characters.

Entity names look like this:

&entity_name;

Entity numbers look like this:

&#entity_number;

To display a less than sign (<) we must write:&lt; or&#60;

Entity names are easier to remember than entity numbers.


Non-breaking Space

A commonly used HTML entity is the non-breaking space:&nbsp;

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 (not break into a new line). This is handy when breaking the words might be disruptive.

Examples:

  • § 10
  • 10 km/h
  • 10 PM

Another common use of the non-breaking space is to prevent browsers from truncating spaces in HTML pages.

If you write 10 spaces in your text, the browser will remove 9 of them. To add real spaces to your text, you can use the&nbsp; character entity.

The non-breaking hyphen (&#8209;) is used to define a hyphen character (‑) that does not break into a new line.

Note

Entity names are case sensitive.


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

Here are some examples:

 ̀aa&#768;Try it »
