HTML character entities

Here's a tutorial on HTML character entities:

HTML (Hypertext Markup Language) is the standard markup language used to create web pages. Character entities in HTML are used to display special characters that have a reserved meaning in HTML or are not available on the keyboard.

To display these special characters in HTML, you can use character entity references, which are codes that represent the character. A character entity reference begins with an ampersand (&) and ends with a semicolon (;), and can be used in place of the character it represents.

Here are some common character entities in HTML:

The & character entity represents the ampersand (&) symbol. This is used to avoid conflicts with the HTML syntax, as the ampersand symbol has a special meaning in HTML. For example:

<p>This is an example of the &amp; symbol.</p>

< and >

The < character entity represents the less-than (<) symbol, and the > character entity represents the greater-than (>) symbol. These are also used to avoid conflicts with the HTML syntax. For example:

<p>This is an example of the &lt; and &gt; symbols.</p>

" and '

The " character entity represents the double-quote (") symbol, and the ' character entity represents the single-quote (') symbol. These are used to avoid conflicts with the HTML syntax and to display quotes within a string. For example:

<p>"This is an example of a quote within a string using the &quot; character entity."</p>

The © character entity represents the copyright symbol (©), and the ® character entity represents the registered trademark symbol (®). These are used to display special characters that are not available on the keyboard. For example:

<p>This content is protected by &copy; 2023 My Company.</p>

By using character entities in HTML, you can display special characters and symbols that are not available on the keyboard, or that have a special meaning in HTML. This makes it easier to create web pages that are more informative and visually appealing.

HTML escape characters: HTML escape characters involve replacing characters that have a special meaning in HTML with their corresponding HTML entity codes to avoid rendering issues.
