Using Installed Fonts
Suppose you want to style certain elements using a font that is available
      on your system. On Windows, it means it was installed in the
        Windows/Fonts directory. In this case, you can reference it directly
      like this:
  section h2 {
  font-family: Calibri;
}Note: 
When installing a font on Windows, make sure you
        select the Install for all users option.
