It has specifically to do with how the browser renders the page. part of the spec for rendering is that newlines are ignored, and the only way to get a line to break in a browser window is with the use of <br>. As for the padding this is the same issue. In Browswer rendering all white space except the first one is ignored, and you have to use for aditionall spaces. ie: 3 space would be ' ' or ' ' Hope that helps!
