Transparent Header with menu above

Hi,

I posted a couple of days ago but now realise I didn’t get a response as I had replied to my own post with additional information so I’m re-posting in the hope I can get some help ASAP on this.

I have a new site which I have configured with menu above, logo below centre. I have found the code that allows me to have a different background colour for the menu to the logo area but I now want to make the area containing the logo semi transparent so it shows the image beneath in a similar way to the transparent glassy header settings (disabled due to the menu above selection).

This is driving me insane now as I have tried loads of different CSS from other posts in the hope they would work but nothing seems to make a difference.

If someone could get back to me ASAP I would really appreciate the help on this as its stopping me from moving forward with my design.

Thank you.

p.s. can someone close my other threads as I don’t want them to get confused?
