484258 Expand Width from 800 px to 1004 px

Our dating site which has roughly 16 pages is of width 800 pixels only and words, photos and graphics on it look smaller than ideal. We hope to expand the width to 1004 pixels, and keeping everything proportional, height increase simultaneously by the same percentage, to prevent things from looking distorted. Graphics in gif and jpeg can be resent to you on a bigger dimension as long as you specify which and what the new width and height ought to be, as we still have the psd files for these and can supply these. You need not create these graphics for us again. But words and photos which are controlled by php need to resized upwards to look way bigger and more catchy. Hope the php programmer is not just a tech geek, but a little bit of artistic taste here to choose what can be more eye-catching ideally. The colour to change from orange to purple. I will give the exact RGB code when programmer is doing, to change to purple colour. (Graphics like gif or jpeg will be supplied to be in purple; need not design them from scratch.) 2 more tasks (for LCD screen) -On a wide LCD screen, the site looks indented to the left. This is Ugly. Centralize all the pages horizontally, because getting centered on the screen will look neater. -The top navigation bar on each page is not properly matching the cursor position with the mouse position, on an LCD screen. When Mouse is pointing at one menu, the dropdown of the submenu items displayed are those that are 2 cursors to the right of the mouse-pointing's chosen menu. So, misalignment on LCD screen Final thing: This site is coded in php, smarty ie tpl files, and a bit of css.
