I tried to move the module to position "above content" but then it loses its style format. How can I fix it so that it retains the same style as if published in position "user 4"
I am not sure what you are trying to copy, but in custom CSS try changing classes ".testimonialsrow .list_carousel" to ".abovecontent .list_carousel". So, wherever you see ".testimonialsrow", change it to ".abovecontent".
