I am managing an application from a vendor which is very strict about customisation. My business team has asked for a simple requirment which has been rejected by the vendor however they did say if we wanted to modify the CSS ourselves we are welcome to do so. I don't have a lot of experiece with CSS so really need some help. i have attached a jpg of how the screen looks (query.jpg) the business wants the column called results to have a different back colour depending on it's value. If it is a negative number then it should be Red, If it is between 0 and 10 it should be yellow, 111 and above should be green.
I have attached also source generated from my browser (query.html) for the screen in the image. i have also attached the stylesheet used currently on that screen. (Acclist.css)
Any help appreciated.
