Hi steveb. Thank you so much for your kindness. I wouldn’t dream of putting you to that trouble, my friend. I’m actually a bit gob-smacked here. It seems the simple act of my describing a problem and reaching out for help has fired up aging neurons!
I’ve come up with two possible solutions, and the first definitely works. I finally figured out how to get the logo to appear in Top Bar, and it looks very acceptable when I use a transparent PNG. The second solution - if it works - will look very stylish, but may cost a little pinch of CPU on each initial page load.
I made an animated hero for the landing page where the sunrise image fades up slowly, and the curve of the sunrise then expands and glows brighter for a moment. The logo then fades up. I used Impact inside Animate for this, and for some reason I don’t yet understand, the logo is perfectly placed without using Target.
The video opener I made for a new YouTube channel “wipes” the sunrise in left to right, then does the same as the Foundation animation, and the effect is stunning.
But I didn’t want to use a video as the site banner. So my second alternative solution involves replicating the home page animation using the smaller sunrise image. It might not work, but it’s worth a try.
You’re correct that the logo doesn’t resize with page width on the forum, but that involves manual coding in XenForo, and I’m no coder, so I don’t know how to fix it. I think most of the seriously ill people we deal with tend to full-screen web-pages and forums to make scrolling easier. At any rate, we’ve had no complaints, and the banner image doesn’t appear on mobile phones anyway.
The forum offers large ZIP files for treating various diseases as well as educational and instructional materials, and these can only be used on a computer, so as long as the forum can be read and navigated on phones and tablets, and it looks clean and uncluttered, we’re not too worried about compatibility with mobile devices.
I come from a print and TV media background, and I confess I find a great deal about HTML utterly unintuitive and frankly baffling.
Thank you again for your kind advice and offer, made at seriously impressive speed.
Namaste - David.
