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.
To display a less than sign (<) we must write: < or <
The advantage of using an entity name is easy to remember. And the Disadvantage of using an entity name is that some browsers may not support all entity names, but the support for entity numbers is good.
A commonly used entity 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 (not break into a new line). This is handy when breaking the words might be disruptive.
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 character entity.
Tip: The non-breaking hyphen (‑) is used to define a hyphen character (‑) that does not break into a new line.
