Question

How do I Center align text in select drop down for all browsers? Its center aligned in Firefox, but it comes to left in Chrome and Safari.

CSS:

  max-width: 850px;
  width: 98%;
  height: 50px;
  background: #ffffff;
  margin: 30px auto;
}

.challenge select {
  width: 100%;
  height: auto;
  background: url(images/select_arrow.png) no-repeat right top #ffffff;
  font-family: 'RexBold';
  text-align: center!important;
  text-align: -moz-center;
  text-align: -webkit-center;
  font-size: 30px;
  padding-top: 7px;
  color: #545454;
  overflow: hidden;
  -moz-appearance: none;
  -webkit-appearance: none;
  appearance: none;
  text-indent: 0.01px;
  text-overflow: '';
}
