Drupal 7 Commerce - How do you style the Please wait loading message/icon when you select an attribute?
For example:

/* Custom ajax throbber style */
.ajax-progress .throbber {
  /* New icon */
  background: transparent url(../images/ajax-loader.gif) no-repeat 0px 0px;
  /* icon is 15px square */
  height: 15px;
  width: 15px;
  /* Alignment, may tweak to suit */
  float: left; /* LTR */
  clear:both;
  margin: 2px 2px 8px 2px;
}
.ajax-progress-throbber .message {
  /* Hide the "please wait" msg */
  display: none;
}
