no theme name change. i think its theme forest item .
It’s probably not. There’s no “table of contents” on the style sheet and the codes look a bit messy (not messy bu un-ordered)
There may be some similar themes on ThemeForest but pretty sure it’s not a theme
This is custom made template. You will not find 100% same template like your example.
If you want such site you can contact me and I will make it.
