It looks like it's not working because you have a space between the text and the ID selector. #.

As you've probably suspected already margin: 0 does indeed set margin on all sides of an element to 0 but it's not taking effect because CSS isn't recognising your ID selector so the browser is ignoring it. 

#gallery {
            margin: 0;
            padding:0;
            list-style:none;
}
