GriffinGraffix on "[Plugin: Category and Subcategory list widget] Removing yellow background styling"

I have style the widget to pretty much what I want but...

for some reason, I can't find the css where the background on hover or focus is yellow. It only shows a very narrow line of yellow in a band below the category icon, title & post count. And only on hover.

The item itself has a white background, it's really a very thin line below it. I did change the padding & margins to better fit the website style.

My site isn't live so it's hard for me to show you. I could send you a screen shot if you give me a place to send it to.

Thanks!!
P.S. I have another issue but I'll write a separate message.
