更改轮播左/右位置 - Bootstrap-3/HTML

Question

我使用 bootstrap-3 在轮播中设置了一些 webviews。要移动的左/右箭头太大，挡住了我页面的某些部分。如何修剪它们以使它们更小。我尝试过尝试和错误来更改 CSS，但没有运气。

.carousel {
  position: relative;
}

.carousel-inner {
  position: relative;
  width: 100%;
  overflow: hidden;

.carousel-inner>.item {

编辑以下CSS：

.carousel-control {
  position: absolute;
  top: 0;
  bottom: 0;
  left: 0;
  width: 8%;  /* change this value to required width */
  font-size: 20px;
  color: #fff;
  text-align: center;
  text-shadow: 0 1px 2px rgba(0, 0, 0, .6);
  background-color: rgba(0, 0, 0, 0);
  filter: alpha(opacity=50);
  opacity: .5;
}
