Centering not working

For some reason centering is not working - stylebyaaron.co.uk/newbuild/index.php

If you look at the sections "location" and the sections "Salons"

any ideas?

Responsive slideshow will always be 100% width , so just adopt images to be bigger. For maps add this to template_css.css:

.phocamaps{
width:424px;
margin:0 auto;
}

I created various images with a white background to make them all the same size but for some reason still left justifys them
