HTML symbols are codes that allow you to add special characters to a web page.
These characters are often not available on your keyboard.
For example, if you want a check mark (✓) or a copyright symbol (©)
you use a special code to display these symbols.
Just like text, you can change their size, color, and position.
To create a particular symbol you can choose from different codes (unicode, hex code, html code, etc.),
all of which are listed below and in subsequent pages.
