HTML Symbols:

In an HTML document the special characters or the reserved characters cannot be typed through the keyboard rather we use the character entity or character reference. A character can also be displayed using the decimal and hex codes of that character. For example, to display ß we can use its decimal, hex and entity reference at the same time. To illustrate this consider the following example:

EXAMPLE

<p> Displaying &#223 ; using the Decimal code </p>

<p> Displaying &#df ; using the Hex code </p>

<p> Displaying &szlig ; using the Entity reference </p>

This will generate the following result:
