Using media query you can divide the images as you like.
.abc{padding:0; margin:0; box-sizing:border-box; width:100%;}
.bcd{display:inline-block;width:24%;}
#media all and (max-width: 360px){
.bcd

display:inline-block;
width:49%;

You can remove the border.
If you remove border, then you can use width 25% for 4 rows in one line and 50% for 2 rows in one line.
