I'm new in blogging. Few days ago I've created a new blog with Frontier template. I've changed the header Frontier logo with my cover photo with image and text. Now, when I see the mobile version, the image is not show on screen and text is extended, non of them look well.
What can I do, and how can I do? I think, may be, I'll need some codes or so, but I could not find info about that.
Thank you in advance.
