HTML Entities are used for denoting reserved characters in the language.
Like programming languages which have reserved words and operators, HTML has reserved characters . If you want to
use text in html formed using such characters , you need special ways of denoting it, else it will be confused as a character which is part of html syntax and hence will take a different meaning.
In above example we find characters <,> and / apart from alphanumeric characters.
In order to use a reserved character as text in HTML, you need to use an appropriate HTML character entity.
Following are some character entities:
< less-than sign -> < or < > greater-than sign -> > or > ≤ less-than or equals sign -> &le ≥ greater-than or equals sign -> &ge   (non breaking space , means space on same line, if 2 words are separated by this they will always remain together on same line) & ampersand -> & or & " double quotation mark -> " or " ' single quotation mark (apostrophe) -> &apos or ' ¢ cent -> ¢ or ¢ £ pound -> £ or £ ¥ yen -> ¥ or ¥ € euro -> &euro or € © copyright -> © or © ® registered trademark -> ® or ®
