Text Color Changes Not Rendering

I see the “change text color” post was resolved, though for some reason the solution is not working for my site. I would like to make the text of the bar be white.

I edited the plugin and made my settings-style.css document:

#wnb-bar{
	position:fixed;
	color:white;
	top:29px;
}
#wnb-bar span{
color:white;
}

The changes will render in the wordpress dashboard, but not on the actual site. I then added those lines of code to my style.css document for my theme, and it still isn’t rendering.

Do you have any recommendations as to what I should do to make the text white on my site? Site: http://www.crowdcrux.com
