menu header to other theme

Unless you’re good in CSS, and have some PHP knowledge, there’s no easy way to just merge two themes into one. Your best bet would be to hire somebody to do it for you, but then again, perhaps there’s a third theme which is better than the hybrid? ??

Firstly thank you for your reply. I’m familiar with CSS and have a little PHP knowledge as well. Also I have to admit I don’t know PHP too much. What I already have tried is: changing my Reddle theme’s header.php to Expound’s header.php in a child theme and also copied all of the CSS rules to my child theme’s CSS what the header.php of Expound theme needed. But unfortunately it didn’t work. Am I on the right way of changing my theme’s header to yours or in a really bad way? ??
Thank you again for your help.

Muzli, it’s not a matter of copy and paste, it’s a matter of cherry-picking the right styles from one theme and applying them to a different theme, which may have different classes, IDs and selectors. It’s an annoying long-lasting process. Personally I would have given up in a few minutes. It’s like trying to squeeze Mercedes doors onto a Toyota, if you know what I mean ??
