Layout of website on iPhone

I designed my website, fisherpix.ca, using Backlight and “borrowed” heavily from the design of other sites.

The layout of my website, as seen on a computer display, is more or less what I want, although tweaking is required. When the site is viewed on an iPhone, the content of the Gallery Sections is wider than the iPhone screen and extends beyond the screen on the right. However, the iPhone layout viewed using Developer Tools in Chrome is fine.

While I have learned enough CSS to tweak the appearance of my site, I am clearly a neophyte in this world. I would appreciate any advice about how to fix the layout problem. Thanks in advance!

Looking at your site on my iPhone 6. Everything looks fine. I’m not seeing anything extending to the right on the galleries page, other album sets, or albums

Thanks Rod. I viewed the site on my iPhone 8. The wonderful world of websites is very strange!
