Post different header functionality is not available, you can change it only from theme options. We will try to add this functionality in our upcoming updates
Thank you for your reply,
How can I choose a different header just for the post ?
We have choosen the transparent header but, it works fine on the home page of our BLOG, although when it comes to a post there is 2 problems:
1 - The header disappears, even with we uploading 2 different logos (dark and Light) Is there a way to have a different header for posts and home?
2 - The header overtakes the feature image and de archive side bar, it is on top of each other, how to fix it? You can check here
