This site contains basic to advanced codes for making framed websites. You can also find very basic inline frame codes on here.
I don't have a real frames tutorial on here, but I do have a 'Frames for Idiots' and an 'Inline Frames for Idiots' page.
If you are using easy/basic/page builders, chances are you won't be able to use frames. (You'll need to switch to the Advanced File Manager.) However, if you are using "Yahoo Pagebuilder", take a look at this site.
