Bring carousel caption on top of the overlay - css

Question

I have this Bootstrap carousel:
HTML:
<div id="carousel-example" class="carousel slide" data-ride="carousel">
<div class="carousel-overlay"></div>
<ol class="carousel-indicators">
<li data-target="#carousel-example" data-slide-to="0" class="active"></li>
<li data-target="#carousel-example" data-slide-to="1"></li>
<li data-target="#carousel-example" data-slide-to="2"></li>
</ol>
<div class="carousel-inner">
<div class="item active">
<img src="http://placekitten.com/1600/600" />
<div class="carousel-caption">
<h3>Meow</h3>
<p>Just Kitten Around</p>
</div>
</div>
<div class="item">
<img src="http://placekitten.com/1600/600" />
<div class="carousel-caption">
<h3>Meow</h3>
<p>Just Kitten Around</p>
</div>
</div>
<div class="item">
<img src="http://placekitten.com/1600/600" />
<div class="carousel-caption">
<h3>Meow</h3>
<p>Just Kitten Around</p>
</div>
</div>
</div>
<a class="left carousel-control" href="#carousel-example" data-slide="prev">
<span class="glyphicon glyphicon-chevron-left"></span>
</a>
<a class="right carousel-control" href="#carousel-example" data-slide="next">
<span class="glyphicon glyphicon-chevron-right"></span>
</a>
</div>
CSS:
.carousel-overlay{
background-color: black;
width: 100%;
opacity: 0.3;
height: 100%;
position: absolute;
z-index: 15;
}
I want the caption and arrow buttons to be on the top the overlay like the carousel indicators. I tried using z-index, but it is not working.
here's a fiddle: http://jsfiddle.net/bM32G/39/

I put the captions and arrow buttons on top of the overlay with z-index in this Fiddle:

I used some !important for simplicity, but it seems to work for me.

To change the color of the content of the carousel you need to refer to, in this case, img. Add the following code to your CSS:
img{
-webkit-filter: sepia(90%) hue-rotate(90deg);
}
Remove or comment out the following line in your HTML:
<div class="carousel-overlay"></div>
You can also look into the following posts:

Answer 3

Since z-index is not working for you..
Try this
.item a img {
opacity: 0.6;
}
.carousel-control {
opacity: 1;
}
.item .carousel-caption {
opacity: 1;
}
