Changing an inline css (element.style)

Changing an inline css (element.style)

I'm having difficulty with this one.  Below is some code from our Sharepoint site that I would like to modify with JQuery.  I would like to modify the background property to 0px (instead of -511px) and change the color to transparent (instead of rgb(255, 255, 255)).  Any ideas as to how to approach this?  I can modify the selector to with with the title attribute but I can't change the values I want to change.  Thanks in advance!
