I am experimenting with a page that loads 5 years of thumbs of past monthly newsletters in groups of 12. Takes a couple of seconds to load the page from scratch.
During that initial loading period, part of the second year is usually visible in the lower part of the screen then disappears when the page is fully loaded. This "show then hide" effect looks tacky to me.
Your second paragraph addresses programming techniques that I am unfamiliar with.
I gather, therefore, that there is no way to alter the loading pattern of the current page.
I'm game to consider a different plan, but radically new may be more than I can absorb today. If you can direct me to some examples or tutorials of the concepts involved, or provide some example code I would be grateful. My goal is to have this ready for the website by the first of next year, so there is time to learn a new trick or two <smile>.
