Can I customize the layout of the blog in magento?

Yes, of course. The extension provides flexible settings for layout customization.

You will be able to choose the layout of the main page for desktop and for mobile separately to ensure better user experience. You are also free to choose whether the homepage should contain only the last post or a list of recent posts as well as their number.

All the layout customizations can be done in System > Configuration > Blog Pro > Layout.
