Make transparent the colour behind logo and menu

Good day, I need to Make transparent the colour behind logo and menu, so the background image can be seen behind both. Can you help me into doing this?
Thank you very much!

it is transparent by default , you can place this at bottom of template_css.css to be absolutely sure:

.sparky_full.logorow div.container {
background: transparent!important;
}

HI, Ivan, thank you very much. If I do what you suggest all white containers become transparent. I need only to make transparent the uppermost container with the logo and the menu. You can see what I mean at www.redavila.net/jardeca1/#
If there is another way it would be a great help.
Thank you

DO you maybe have logorow class defined for all rows in layout editor. That class should be only set for that layout row containing logo.

Good Morning Ivan, I am attaching the css.css file for you to see and advise me.
Thank you again.

I dont need css file, I asked about settings in template options, in layout editor
