UI Deploy

Far too often I see people don’t quite understand the differences between width and device-width (and expanding upon that, other examples such as min-device-width and max-device-width), when using CSS media queries. This misunderstanding results in poor code and ultimately more work for the developer. I’ve seen this question quite often over on the SitePoint Forums, so I felt it was time to give some further explanation. I’ll be touching on this, along with expanding on which option you should be using when building your responsive websites.
