In HTML, entities are special codes that represent characters that cannot be typed or displayed directly in the web page. This includes characters such as angle brackets (&lt; and &gt;), ampersands (&amp;), and quotation marks (" and ').
HTML entities are used to display these characters on the web page without interfering with the HTML code. For example, if you want to display the copyright symbol (©), you can use the HTML entity <code>&amp;copy;</code> instead of trying to type the symbol directly.
There are two types of HTML entities: named entities and numeric entities. Named entities use a predefined name for the character, such as <code>&amp;copy;</code> for the copyright symbol, while numeric entities use a numeric code to represent the character, such as <code>&amp;#169;</code> for the copyright symbol.
Using HTML entities is important for ensuring that web pages are displayed consistently across different platforms and devices. Without them, characters that cannot be displayed directly in the web page would be replaced by question marks or other symbols, which could make the page difficult to read or understand.
