Center the Effing Div

.image {
  margin-left: auto;
  margin-right: auto;
  width: 415px; /* fix the width while we're at it */
  text-align: center; /* and we'll center the caption as well */
}

Centering a div

This approach will center a <div> in a scenario where you want to have the body of your page centered on the screen, but leave the text left aligned.

body
{
 text-align: center;
 align: center;
}
 
#container
{
 text-align: left;
 margin: 0 auto;
}

align:center / margin: 0 auto are for IE/FF.
