Rob,
Have you tried the “advance_hover_color” option that is available for the advance button? You could make it the same as the “advance_color” option, that way there would appear to be no color change on hover.
[intense_content_section background_type="image" image="630" height="400" breakout="1" show_advance="1" advance_color="#ff0000" advance_hover_color="#ff0000" advance_icon_source="elusive" advance_text="Next" scroll_offset="100"]
[/intense_content_section]
If you want to make the color transparent, you can use rgba colors as well. Here is an example. This advance button will have a transparent background at all times, including on hover.
[intense_content_section background_type="image" image="630" height="400" breakout="1" show_advance="1" advance_color="rgba(0,0,0,0)" advance_hover_color="rgba(0,0,0,0)" advance_icon_source="elusive" advance_text="Next" scroll_offset="100"]
[/intense_content_section]
If this doesn’t help, please let us know.
Thanks!
