Bootstrap carousel inner images - css

Question

My carousel is a 1200*500 dimension one. When I put an image of the same dimension , its not taking the full width of the carousel , just partially.
I tried using the "fill" class in my html code but its not working , I also tried with this css code:
.carousel,
.item,
.active {
height: 100%;
}
.carousel-inner {
height: 100%;
}
Nothing seems to be working. Any help please
HTML Code:
<div class="container">
<div class="row">
<div class="col-md-12">
<div id="carousel-example-generic" class="carousel slide" data-ride="carousel">
<ol class="carousel-indicators">

<li data-target="#carousel-example-generic" data-slide-to="1"></li>
<li data-target="#carousel-example-generic" data-slide-to="2"></li>
</ol>
<div class="carousel-inner">
<div class="item active">
<img src="images/18.jpg" alt="First slide">

I did this example for you (it's a bit simple, but will help you).
The change I made, compared to yours, is that I am now adding the image as background in a DIV, not in an image element. Thus, we can control the display, regardless of the size the image has.
.carousel-img {
width: 100%;
height: 400px;
background-size: cover;
}

<li data-target="#carousel-example-generic" data-slide-to="1"></li>
<li data-target="#carousel-example-generic" data-slide-to="2"></li>
</ol>
<!-- Wrapper for slides -->

<div class="carousel-caption">

<!-- Controls -->
<a class="left carousel-control" href="#carousel-example-generic" role="button" data-slide="prev">
<span class="glyphicon glyphicon-chevron-left" aria-hidden="true"></span>

<a class="right carousel-control" href="#carousel-example-generic" role="button" data-slide="next">
