Specifically, while using the white color scheme with 5.5.0 I could add the following code (see below) to "floatbox.css" and change the "info..." link color away from it's constant default color of #000 [black] for all of its various states. Also, somehow I was even rid of its default "text-decoration:underline" upon mouse hover -- though I seem to have forgotten just where I turned that off.
With these couple of minor tweaks in 5.5.0 I had the "Info..." link match the style of other links on my web site. Is this still possible?
.fbx#fbx .fbInfoLink a:link{color:#800000}
.fbx#fbx .fbInfoLink a:visited{color:#800000}
.fbx#fbx .fbInfoLink a:hover{color:#FF0000}
.fbx#fbx .fbInfoLink a:active{color:#800000}
