'Front-End web development' Track | How to make a website : Layout Issues

Hi all, I'm at stage 8, at the testing phase.

I've completed every step correctly so far. I've downloaded the project files before asking to see if there's anything different in my code, but it's not. Everything is the same with Nick's files.

When I made the adjustments for wider devices with media queries (at least this is where I noticed it to be honest), my "original" layout for mobile (since that's our main.css - for mobile), screwed up a little.

Here's a link where you can see how the site is rendered in many devices. It's live, so you can navigate through the pages.

My main issues are:

• The 'about' page In some cases the photo is not where it should, but on the right of the header instead (!!!!!)

-The 'portfolio' page: The gallery isn't displayed correctly on IPhone, although it's fine on Galaxy-y. (There's a chance the problem isn't only on iPhone, but on every similar-sized device)

• Less important: The image styling (example the border-radius set to make it a circled image) isn't working on all devices. Also, it's not centered as it should in many cases.

Any ideas???? :)
