Following a recent jAlbum/Neptune upgrade I've discovered a display anomaly that I can't solve. The fullscreen icons no longer display on iPhones.

Homepage is JRET.net and is fine when viewed with my Mac Studio's displays - Dell (1920 x 1200) and ASUS 5K (checked it all the way to 5120x2880). Homepage is also fine with iPad Pro running IOS 26.3. The fullscreen icon (upper right corner) is missing when viewed on iPhone 16 Pro (standard screen) running iOS 26.3.1 and also missing when viewed on iPhone 15 Max (large screen) running iOS 26.3.

The homepage was recently updated to jAlbum 39.2.2 and Neptune 132.

On the two iPhones the logo is no longer centered with the missing icon on the right. I immediately suspected that the CSS code to keep the center logo at the top of the display was the culprit - .ja-logo {padding: 0px !important;} so I removed that line of code & rebuilt. The icon was still missing but the logo was now centered and dropped down. Since that didn't correct the missing icon I added the CSS code back & rebuilt.

Next clue: from the Homepage click the upper left INFO icon and then click the PHOTO GEAR icon. The GEAR album has not been updated and is running under jAlbum 39.2 and Neptune 131. The fullscreen icon is not missing with this configuration.

I have two other sites that use jAlbum/Neptune. I use the fullscreen option in all. I've only updated a couple of albums but the result is the same. Following the update the fullscreen option no longer displays on the iPhones.

At this point I suspect Apple has somehow broken something with their new Tahoe adventure. If that is indeed the case I imagine I have a better chance of winning the lottery than getting them to admit it, much less fix it. Any ideas? solutions? Hopefully, it's something simple, but I'm stumped at the moment.

The funny thing is that I actually did read the release notes as I was installing the updates but somehow did not make the connection when I noticed the "missing" icon on the iPhone.

I removed the CSS code and rebuilt. The logo is now properly centered with the only "casualty" being the logo no longer at the top of the display in either orientation (portrait or landscape) when viewed on the iPhone. Looks fine on all other displays - can't test on Android (don't have one) and can't test on Windows.

Simple solution that I can live with. I did prefer the logo closer to the top but it's fine as is. Thanks again for your prompt solution.

The css file did the trick ... many thanks. I'm also glad to learn about visibility:hidden and the layout difference.

Will the next Neptune update include the css changes?

I still need to go back and do some poking around, just to make sure I haven't broken anything else. Getting things centered is always tricky - CSS doesn't handle it well, surprisingly. New coders are always mystified to discover that float: center; isn't a thing.
