Apologies – didn’t realize I was asking for a very big thing. The Client simply wants the website to be visible on all devices the same way. In other words, on a tablet – the width of the screen both portrait and landscape. On the iPhone, the width of the iPhone screen in both portrait and landscape. My assumption was that this could be achieved by setting the outside container to be a set width in pixels – but then also shrink to 100% of the viewer size when it came to tablet and mobile.
I was a bit frustrated because the majority of the themes I purchase from Theme Forest nowadays are responsive, but have a check box in the theme options that allows me to turn the responsive feature on/off.
If there is no easy fix just let me know and I’ll figure something out.
