How do I get out of a frame set?
Here is the answer,
You only have to add the TARGET attribute to the link that takes readers to the intended 'outside' document. Give it the value of _top.
In many current browsers, it is not possible to display a frame in the full browser window, at least not very easily. The reader would need to copy the URL of the desired frame and then request that URL manually.
I would recommend that authors who want to offer readers this option add a link to the document itself in the document, with the TARGET attribute set to _top so the document displays in the full window if the link is followed.
