How to center thumbnails for all screen-sizes?

Question

body{
    width:auto;
    color:white;
    font-size:15px;
    width:100%;
    max-width:1980px;
    min-width:334px;    
    margin:0px auto;
}

This is my code. I need thumbnails to be in the center for all screen resolutions. But I can't do it. I even tried tag. It didn't work either. What should I do?
