Jquery – remove border around bxslider slides


I am using jquery bx slider. I want to remove the border around the slides.
How do I do this?
I tried this, but it didn't work:

ul.bxslider {
  -webkit-box-shadow: 0;
  -moz-box-shadow: 0;
  box-shadow: 0;
  border: none;

Any other ways to do so?

As accepted answer is no more correct (in 2018 - bxSlider v4.2.12), I added here working CSS:

.bx-wrapper {
  -moz-box-shadow: none;
  -webkit-box-shadow: none;
  box-shadow: none;
  border: 0;

!important is not necessary, if you add this CSS after linking to bxSlider's CSS file.
