Important - No compatibility issues in the coding - Priority given for a clean, short code - We use SSL Example of the store to edit: [login to view URL] (just an example to see the code) We appreciate your attention and your proposal If you have any question please tell us You do not need to develop the code yourself, just find fixed banner and slider codes that work for mobile and test in our script.
