Purpose: Cascading Style Sheets (CSS) is used to style our web apps.

These files have a file extension of .css. To use this file in the index.html file, 
we use a link tag in the head section of the index.html file.

Notice the index.html file is divided into a head and body sections.
- The head section is used to define the title of the web page and link to css files and icons.
- The body section is used to define the content of the web page and link to JavaScript files.
