Centering a Div

One of the many ways in which Firefox, Netscape, Internet Explorer, and other browsers interpret the same HTML code differently is when margin: auto is used to center a block on a webpage, such as a div section. Adding margin: auto to 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: center to the style definition of the body tag.
