The navigation bar at the top of the home page is transparent. How do I remove transparency such that the navigation bar background color comes on top of (or above) the slideshow?

Nevermind, I found out how to do it by editing front_params_output.php

I changed
#header.has_slider{
background:<?php echo $this->hex_to_rgba
($header_back_color, 0.20); ?> !important;

to
#header.has_slider{
background:<?php echo $this->hex_to_rgba
($header_back_color, 1.00); ?> !important;

I just commented out the whole section. That works well.

Great Gaute!
