HTML Entities

HTML character entities are used to replace the reserved characters in HTML. With the help of these, you can also replace characters that are not present on your keyboard by entities. These characters are replaced because some characters are reserved in HTML. HTML entities provide a wide range of characters which can allow you to add icons, geometric shapes, mathematical operators, etc.

For example:

if you use less than (<) or greater than (>) symbols in your content, the browser can mix them with tags that is why character entities are used in HTML to show reserved characters.

How to use an entity:

You can add an entity in your HTML document by name or by numerical characters. Each entity starts with the symbol ampersand (&) and ends with a semicolon (;).

HTML entities Syntax:

  • &entity_name;

  OR

  • &#entity_number;

<!DOCTYPE html> 
<html> 
<head> 
<title></title> 
</head> 
 <body> 
    <h3>HTML entity example</h3> 
    <p> "This is the content written within entity"</p> 
    <p> <p> Paragraph tag </p> 
 </body> 
</html>

 Some diacritical marks are as follows:

HTML invisible Characters

There are some HTML invisible characters entities that can insert non-visible characters or whitespace into an HTML document. These entities can be used to create more readable or structured HTML programs, or to add special effects to the appearance of the document

  1. &nbsp; - Non-breaking space: This entity represents a space character that prevents the browser from breaking a line of text at that point. It is often used to create space between words or to prevent words from being split between two lines.
  2. &zwj; - Zero-width joiner: This entity is used to join two or more characters together, without adding any visible space between them. It is often used in languages such as Arabic, Hebrew, and Indic scripts to connect letters together.
  3. &zwnj; - Zero-width non-joiner: This entity is used to separate two characters, without adding any visible space between them. It is often used in languages such as Arabic, Hebrew, and Indic scripts to keep letters from joining together.
  4. &shy; - Soft hyphen: This entity represents a hyphen that is used to indicate a possible line break within a word. If a line break is not necessary, the hyphen will not be displayed. This can be useful for long words that may not fit on a single line of text

These are just a few examples of the invisible character entities that can be used in HTML. Other entities, such as &zwsp; (zero-width space) and &lrm; (left-to-right mark), can also be used to add invisible characters to HTML code.
