How to pass the Frameset Test?
In the context of a web browser, a frame is a part of a web page or browser window which displays content independent of its container, with the ability to load content independently. The HTML or media elements in a frame may come from a web site distinct from the site providing the enclosing content. This practice, known as framing,[1] is today often regarded as a violation of same-origin policy.
In HTML, a frameset is a group of named frames to which web pages and media can be directed; an iframe provides for a frame to be placed inside the body of a document.
Since the early 2000s, concern for usability and accessibility has motivated diminished use of framesets and the HTML5 standard does not support them.
