How to centre images using code??

Hi, I am working on a 7.0 site where I need the gallery images to be larger on mobile . I know how to get the code for each image and make them larger however they are not entered now. Does anyone know the code to centre the images. This is my code below.

/* CSS FOR MOBILE */
@media @mobile {
/* Insert Code for Mobile Below This Line*/

  #collection-615435ef6ec44457a9705c06 {  width: 150% !important; margin: 0 auto; }
 

/* Insert Code for Mobile Above This Line */
}

Thanks
