Stylesheet edits frontpage

This has probably been asked but I can't seem to find it. Simply put I have done all the neccessary installs and have come across a problem where I only seem to be able to adjust the width of the main front page. When clicking on a section the whole thing nolongers sets to 100% across the screen. Any ideas I apologise if this is simple. Please check out the website so far https://www.pixelgamer.co.uk

You have 2 options:

1-Add the following to your css:

.centershop {width: 100%} 

2-Download the most recent version of Sophy Blue Template, where this and other little issues has been fixed.

Thanks for the quick response very appreciated, and nice one on a good template. Can I just ask a quick question. Is it the case that all the changes are just in the stylesheet or are the other changes throughout the template. Just that I have personalised it quite a lot and do not want to start from scratch.

Thanks again for any help you can give. Ta!

Yes, the css and readme file where the only only ones edited. It's very important to read the new readme file.

Readme read and copywrite reattached.
