Carousel Left Chevron margin issue

[X3Technology]

The following CSS give the left chevron a negative padding of 15px. As a result, the left chevron is 15px closer to the left edge than the right chevron is to the right edge. This is a bigger issue if the carousel is place in a full screen width section as the left chevron will be partially off the left edge of the viewport. Not sure what the rationale was to give it -15px left margin, but I suggest removing it.

.carousel-control .glyphicon-chevron-left, .carousel-control .glyphicon-chevron-right, .carousel-control .icon-prev, .carousel-control .icon-next {
font-size: 30px;
height: 30px;
margin-left: -15px;
margin-top: -15px;
width: 30px;
}
