how to customize jfbconnect login text color and background color?

To change the color of the background or text, you'll want to add a Module Class Suffix to the module itself. To do so, in the JFBCLogin parameters, on the right side, simply set the Module Class Suffix to "-jfbclogin", for example. Then, in your stylesheet, you can add the following to style the box however you want:
.moduletable-jfbclogin {
color:#FF0000; // Set the text color to bright red
background:#00FF00; // Set the background to green
}

Hope that helps, but if you need more info, let me know!

NLM,
This may go over your head, so if so, just let us know. The Module Class Suffix parameter only works if your Joomla site's template is setup to take advantage of it. In your template's file that includes the module position that you have the login button in, the style must be set to xhtml.

To check this, you should check (usually) the index.php of your template file (in /templates/<YOUR_TEMPLATE>/index.php. In this file, you'll want to look for the include command for the module position you're looking for. It should look like below:
The name is the module position (left, user1, top, etc) and the style is set to xhtml. If this isn't how the module position inclusion that you're template looks like, try adding the style=xhtml bit, and the module class suffix should then start working.

Let me know how that goes, or if it just adds to your confusion. Hopefully, this will get you squared away.

Good luck!
