I have a website designed with css.
I'm now changing the css layout.
The problem is that the code is a little messy as many graphic tags where done without using styles and there are many pages to check, put away hand-done tags and replace with styles.
The work is very simple, but you must be precise, check every page with new stylesheet, check if layout is ok and if necessary add some style to the stylesheet(if you don't know css I will explain you how to do it).
Sometime you can use search and replace to correct some features, but not all pages are alike.
Even if I'm not a designer I cleaned the code on some pages myself and I think to do the whole work well you need about 6-7 hours + downloading and uploading time with about 4-7 minutes work for each page.
There are about 120 pages to do.
