html - Center an object tag in a div -

-

how can center object content within div? 

.parent{ background-color:yellow; }  .ob{ margin: 0 auto; } </style>  <div class="parent"> <object width="400" height="400" class="ob" data="helloworld.swf"> </object> </div>

thanks in advance!

an object element has inline style default, , margin: auto applies block-level elements only.

add style:

.ob {   display: block; }
