how can i transparent this sticky primary navigation

are you using the colors add-on?

no .i just customize from the theme option !

So you want the background to only be transparent when it's sticky?

yes tom i do !

sorry i want the sticky and the no sticky to be transparent /

Try

.main-navigation {
    background: none;
}

Let me know if this works :)

If you want both to be transparent, deleting the background values in "Customize > Colors > Primary Navigation" should do it.

i did it tom .
i deleted the code that was there and save .
maybee u need to insert a code .
look here

That looks right.

Can you link me to your site?

Your navigation is transparent as far as I can see.

The black background is your header background.

i dont see any black background !
and the problem is the color boxes that appears
on the nav menu when it sticky and when its not that is the problem :)

This colored box?: http://screencast.com/t/8G4epZFn
