Responsive design without media-queries/grid

I have been digging around to see if there is any material on creating responsive web designs without media-queries/grid (so that my designs can be compatible with IE 6/7 as well). I have, thus far, found nothing and would like to know if such a thing is possible and if so, direct me to resources where I may be able to learn further.

If you make your pages for full-size screen first and then use css to respond to smaller screen you should be OK. IE6 / 7 are probably not going to be on any small screen devices. Browsers generally ignore css they don’t understand so older machines will happily display your big screen version and newer browsers will benefit from your css regardless of screen size.
