Centering the facebook like box in the sidebar

Hi Chandra. Just takes a bit of math.
Sidebar width: 340px
FB box width: 250px
Leaves 90px to divide equally on both sides = 45px
Default widget padding is 30px so need to add 15px on the left:

.fb_iframe_widget {
    margin-left: 15px;
}

It helps but in smart phone, it did not make any difference.

Try using a media query:

@media only screen and (max-width: 479px) {
  .sidebar .widget {
    margin-left: 25px !important;
  }
}
