How can I change the size of my sticky header logo?
Please, go to Betheme -> Theme options -> Global -> Logo, and check the option Remove max-height & padding for Sticky Logo.
If the result will not suit you, I suggest using the Header builder, where you will be able to customize it however you want.
I encourage you to check our Facebook group if you have not done it yet. You can talk there about Betheme and confront your experience with others:
Perfect, thank you!
