Hi, I am making a site which will run in all ipods; i-pads;i-phone, androyed mobiles as well as desktop and laptops with any resolutions.It must have only one css and must follow 960 grid.I must make it fluid design.but when I tried to specify height by percentage( insted of pixels, other wise the site looks ridiculous on laptop and desktops.)its not rendering the percentage value given.What am i doing wrong?

Not enough info to answer that one. Try posting your markup and CSS, using the code button .
