Please What is the meaning of 'rel' in the link tag of CSS

Answer 1

Did you mean the rel attribute of a link tag in HTML?
That describes the type of relation you want to link some source.
Examples:
<link rel="stylesheet" .... is a link to a stylesheet file

<link rel="icon"... Is a link to an icon file.

Answer 2

Both relative and absolute paths can be used to define the href for the CSS file. In our example, the path is relative, as the CSS file is in the same directory as the HTML file.
