About Frameset Test

Check if your page is using frames, which divide your browser window into multiple sections where each section can load separate HTML documents. Frames create problems for both users (e.g., by creating unexepected behavior with printing functions or use of the back-button) and search engine robots (by complicating the crawling process). Avoid use of frames when possible.

Framed pages do not behave the same as normal HTML pages and can lead to confusion and awkwardness.

A well-designed navigation structure using CSS layers is infinitely preferable.
