I’m having the same issue. THe gradient is left-aligned and does not go completely across my screen (2560 x 1080). You already have a user on my site. Can you help me to make it so it will always be full-width?
There is an easy fix for this issue. You have to open your style.css file located inside the elvinaapro theme folder. (Note: you need to access your control panel for that)
Open this file in any text editor and find line number 1766 and replace no-repeat with repeat only.
