Thank you Nikko.
I have next problem with logo in header menu .
In E-commerce demo logo ist resized, but i will have pure logo-without any effects ( Ex. opacity, transition ..) like in OnePage demo. I read many comments on this forum,but i don,t find resolution for my problem.
In .css i tested settings for:
#header_main > div.container.av-logo-container > div > span > a > img

and

.header-scrolled .logo img, .header-scrolled-full .logo img,
.header-scrolled .logo a, .header-scrolled-full .logo a,
.logo img, .logo a

Thank you
This is the same image- 2000px x 1333 px, the same settings in editor, but looks terrible.
What about white pattern (background-images/dots-for-dark-background.png) from one page demo? Is possible paste it in enfold2017 demo?
