Resizing browser dimensions question

Hi All,

Question for you. I’m about 99% done with a site I’m working on and the client just hit me with a low blow. The designs that I got from their designer were a certain dimension, so I built the site with the assets based on those dimensions and now that I’m nearing the end of the project, the client seen the site on their 13 inch macbook and freaked out “everything looks too big!” is what they said. Is there a way to resize assets based on browser size without having to go in and do too much modifying? I tried looking this up, but I got a bunch of Event.RESIZE responses which I don’t think I’m looking for that. Anyway, please let me know what my best possible options are.
