Rewriting the present CSS so that the same can show in print format for DOMPDF

We have the standard HTML / CSS written for the pdf report. However this needs to be edited / changed / rewritten based on the rules of DOMPDF. so that it shows in a print format that can be converted to PDF. We have our own coding team so no PHP coding is required by this person. Requirement is - people with HTML / CSS Skills having good understanding of DOMPDF rules . People with PHP knowledge will have a distinct advantage as you would need to install dompdf to check if the print format is proper or not. Total no. of hours expected to complete this between 8 to 15 hours. So pls read this before just bidding for it.
