One of the many ways in which Firefox, Netscape, Internet Explorer, and other browsers interpret the same HTML code differently is when
margin: autois used to center a block on a webpage, such as a div section. Adding
margin: autoto the style definition for a block will result in the block being centered when viewed in Firefox or Netscape, but it isn't sufficient to result in the display of a centered block in Internet Explorer. To have the block centered in Internet Explorer, you have to also add
text-align: centerto the style definition of the body tag.
