I'm designing a website that suits the screen size but should work in ie7 to more,How can I adapt the website to user's screen resolution no matter what screen resolution the user have in ie7? thanks.
--edit--
this site is my reference http://www.rei1440project.com/#
Check out css3-mediaqueries-js, which attempts to provide media query support (a key component of responsive web design) to legacy browsers.
EDIT: Check this out for fluid grids and this for fluid images. Both seem to include Internet Explorer accessibility.
