1. Maybe you are using the word "frame" wrong, as they are considered bad form and not recommended for usage on websites any more.
2. The usage that you reference in your second link literally has no "styles". To create a "style-less" site, remove the style link in your
header.php and then go through the
index.php template file and remove the "includes" for comments, sidebar, and so on.
Now, when you do that, realize that you will also loose the power of navigation and other elements that are critical to the success of a website. There are few things I HATE about searching for things on the Internet than running into a site that has a great article but no link to the home page, about, or any other articles on the site so I can read more, find out more, or find out who did this neat thing. Luckily, these types of pages are getting fewer and fewer on the Internet.
