@playnethemes, thank you, I searched that category before, maybe I should look better, I think it’s something similar to that.
@cline123, true, it is similar actually, but I’m not sure what changes I can do on these templates in terms of colors, new sections, etc. For example, can I change the background color?
Most themes are very customizable nowadays, you shouldn’t have any trouble. Specific questions are best answered by the theme author.
