Styles: WORD vs FrontPage

[Latitude]

We are familiar with the concept of styles as used in Microsoft Word. In
Word you create styles by creating the style and then saving the file. The
style is created by using the GUI interface rather than entering things
like: font-family: Times New Roman, Times;
color: rgb(153,153,51).

When using CSS in FrontPage is it correct that we need to actually enter the
text of the styles rather than defining styles by 'doing' or using the GUI
to create the CSS?

As a user and lover of-all-things-GUI, we need to know if when creating CSS
in FrontPage, we need to make changes to the defining text in the .css file.
