Venture theme - made header transparent but other sections are moving up underneath

[DeadEndStreet]

Hi there, I hope someone can help me with this.

I have made my header section transparent but the page seems to move up almost as if I deleted the section not made it transparent.

So now  have 'testimonials' sat where the header (white background formerly was' - cant work it out.

A secondary question - I cannot seem to make the navigation bar transparent either.

Any help would be appreciated.
