CSS class - id

This tag allows you to define a new section in an HTML document:

• <style> </style>

• <div></div>

• .div

• #div

The difference between the class selector and ID selector is...

• The identifier ID is created using a dot (.) and the class uses a # symbol.

• a class must be used just once whereas an Id can be applied multiple times on the HTML.
