How does the width of this Template work?

In other words, is there a minimum & maximum width setting for desktops & tablets? In the past, Ive made sites about 960 width, so the format could be controlled.

I'm concerned that if it is completely responsive, how can you make a site look good for both 800 width & 1500 width screens?

It uses the Bootstrap responsive fluid grid system

You can easily tweak the container widths for specific screen widths using this technique.
