HTML Entities are codes or sequences used to represent special characters and symbols that have specific meanings in HTML, like angle brackets (< and >) or ampersands (&). These characters are often used to define the structure of an HTML document itself. However, there are instances where you may want to display these characters on a webpage without having the browser interpret them as part of the HTML structure. In such cases, HTML entities come to the rescue.
In the below PDF we discuss about HTML Entities in detail in simple language, Hope this will help in better understanding.

HTML entities enable the proper encoding of characters, ensuring that text is displayed accurately, regardless of the character’s nature. For example, the entity © represents the copyright symbol ©. Without proper encoding, this symbol could cause issues in your HTML document.
Using HTML entities is essential for web accessibility. They make web content more accessible to people with disabilities by ensuring that screen readers and other assistive technologies can interpret and convey the content correctly.
- Cross-Browser Compatibility:
Different web browsers may interpret characters differently. Using HTML entities ensures consistent rendering across various browsers.
