This page tests HTML transition effects in framesets. There are 25 effects that can be applied on site enter, site exit, page enter, and page exit. The test will see if the effects can be applied to frameset pages as a whole (I don't think that's possible, given the structure and limitations of HTML framesets), or to individual frames within a frameset.
Now for the transition effects test and explanations: page-enter was used for the test, but the transition effects were not applied to the main frameset. (If you 'View Source", you'll see it in the section.) I'm assuming that since the main index frameset isn't 'seen' (the frameset file has no content which appears on the page) there is nothing to apply the transitions to if you put the transitions meta tag in the main frameset. (I was wondering if the effects would be applied to the 'noframes' text, so I tried it using Opera 5 and 6 browsers, which can be configured to have framesets turned off. The transitions still didn't apply to the 'noframes' displayed page and content...checking standard HTML pages with transition effects, it seems Opera doesn't support transitions at all.)
Since in this example, the nav bar frame never changes or gets refreshed, I didn't put the transitions meta tag in there. I did put the transitions meta tag in the 2 versions of the content stuff frame and linked both in the nav frame (along with 2 external reference charts: a Web Page Transitions Meta-Code Chart and the Character Entity Reference Table with Extended Character Set Test pages, along with a home page link, to confirm proper linking that breaks out of the established frameset). On the initial frameset load, no HTML transition effects were seen, but if you click the second content stuff link, the transitions effects apply in the content frame...and will apply as you switch between the two content stuff frame content pages. Unlike standard HTML pages, refreshing the page does not reapply the HTML transition effects to the content frame.
