HTML individual references are brief bits of HTML, typically called person entities or entity codes, which can be used to display characters that have unique which means in HTML in addition to characters that don’t appear for your keyboard.Characters with special that means in HTML are known as reserved characters. For example, left (<) and proper (>) angle brackets are reserved in HTML to identify the hole and final tags of factors.Characters that don’t appear in your keyboard include things just like the copyright symbol (©) and the mathematical value pi (Ï€).
If we want to use those types of characters in an HTML record and have them appear when rendered in a browser we use HTML individual references.A Practical Example
Let’s say which you need to display a block of HTML in an internet web page and have the element tags display up on the web page. You may also try to do so by using honestly losing This is a listing of items. This is a listing of objects.</p> blocks around the block of HTML you need to display. However, what you may find is that in spite of the tags surrounding the little bit of HTML in query, it's going to nonetheless be processed as HTML and rendered with the aid of the browser. What we are able to do is update all of the special characters with the ideal man or woman references to save you the browser from processing the code.
Let’s see how that code renders inside the browser.

This is a listing of gadgets.</p>
- List Item A</li>
- List Item B</li>
- List Item C</li> </ul>
As you could see, the code blocks across the first block of code did no longer save you the browser from processing the HTML. However, with the aid of replacing certain characters within the 2nd block with HTML man or woman references, we will display the code block as HTML markup.Character Entity Format
In HTML, there are 3 exceptional methods to layout a man or woman entity. You can use the individual name, a Unicode value, or a number of. For example, an ampersand can be displayed using any of the subsequent entities: &, &, or &.
In all three instances, the format appears basically the same. Each entity starts offevolved with an ampersand (&), followed through the individual call, Unicode, or wide variety reference, and ends with a semicolon. When more than a few is used, it have to be preceded by the pound image (#), and while a Unicode cost is used, it should be preceded by means of a pound symbol and the letter x (#x).
Most people use individual names as opposed to Unicode values or numbers while adding named characters to HTML files considering they’re plenty simpler to consider, but it’s similarly appropriate to use both the Unicode or quantity references as well.Diacritics

These are marks that seem at once over the previous letter and encompass accessory marks and tildes. Here are the three most common diacritics:MarkCharacter NameNumberExampleAcute´́áproduces áGrave`̂â produces âTilde˜̃ã produces ã
