HTML Entities


In this chapter we learn about HTML Entities.

When Characters are not present in keyword can be replaced by entities.


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: &lt; or &#60;


Non-breaking Space

A common character entity used in HTML 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 at the end of a line. This is handy when breaking the words might be disruptive.

Examples:

  • � 10
  • 10 m/s
  • 10 km/h
  • 10 PM

Another common use of the non-breaking space is to prevent that browsers truncate 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.

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 (encoding) used in the page.

Here are some examples:

Mark Character Construct Result
  ̀ a a&#768;
  ́ a a&#769;
̂ a a&#770;
  ̃ a a&#771;
  ̀ O O&#768;
  ́ O O&#769;
̂ O O&#770;
  ̃ O O&#771;
