Gromit continues to improve ... many, many thanks for that.
I've recently observed a screen display behavior that seems odd. I think it's always been there and not a result of any updates. On my home page I'm using a background image with title bar & thumbnail folders plus the icon link to an infopage. On my computers and iPad the background image behaves as expected on both the home page and infopage. But on my Samsung Android the background image on the home page appears to be zoomed in while the infopage displays as expected. I've played around with some settings and rebuilt the page a few times - even tried looking at the code & CSS but not really sure what I'm looking for. It seems to me that the background image should display the same on both pages. Any ideas?
I just did a quick test with a small album with an info page and a background image. In Firefox on my S7, it works perfectly - just like it does on the desktop. But in Chrome on the S7, the background image CSS is ignoring the background-size:cover; attribute. So, the appearance of the background image is heavily dependent upon how much material is on the page. It looks different with different numbers of rows of thumbnails, for example.
I believe I've found the workaround, and I'll incorporate it in the next release, if it doesn't louse up something else.
Try this: head for Gromit > Code > CSS and enter:
Make the album and upload it again. Let me know how that works out.
