Background of what? Breadcrumb NavXT does not ship with CSS, so you will need to apply styling via modification of your current theme’s style.css (or child theme’s style.css). The class you need to select when styling depends on how you are calling Breadcrumb NavXT. I suggest using something such as Firebug in Firefox or the build in inspector tools in Chrome to determine what selector you should use and test CSS styling modifications.
While I was poking around in: breadcrumb-navxt/includes/mtekk_adminkit_tabs.css
I found:
#hasadmintabs ul.ui-tabs-nav li.ui-tabs-active a{background: #ffffff;border:1px solid #ccc; border-bottom-color:#f1f1f1; height: 25px; color:#464646; font-weight:normal; padding:1px 13px 0;color:#000;}
So, I thought that because ‘transparent’ was established in the background code, that I could change it to #ffffff.
I guess not?

Please don’t modify files that ship with the plugin, your modifications will be lost when you update the plugin.
The file you are modifying is the styling for the tabs on the Breadcrumb NavXT settings page (it is part of the mtekk_adminKit library). Modifications to that file will not affect the styling of your breadcrumb trail. You will need to make your styling modifications elsewhere (e.g. your theme’s style.css). As I stated above, Breadcrumb NavXT does not ship with CSS for the breadcrumb trail.
