removing space in between photos : <p>I want to remove all the space (padding if any) in between 4 photos and to be in full width of the browser without space. I tried many things including setting the padding to 0 but, I got success to a certain extent, still I get tiny white space between photos. Do anyone have idea what this white space occurs even when padding is set to 0.</p>
