Certain characters are reserved in HTML, and using symbols like less than (<) or greater than (>) may cause the browser to interpret them as tags. To prevent this, entity names or numbers can be used to represent these reserved characters. Entity names follow this structure:
| &entity_name; |
Entity numbers are represented in this format:
| &#entity_number; |
To display a less than sign (<), we must write it as < or as <.
| Entity names are simpler to recall compared to entity numbers. |
