<li data-target="#imgCarouselSlider" data-slide-to="1" ></li>
<li data-target="#imgCarouselSlider" data-slide-to="2" ></li>
<li data-target="#imgCarouselSlider" data-slide-to="3" ></li>

</div>
<div class="item">

</div>
<a class="carousel-control left" href="#imgCarouselSlider" data-slide="prev">
<span class="icon-prev"></span>
</a>
<a class="carousel-control right" href="#imgCarouselSlider" data-slide="next">
<a class="carousel-control right" href="#imgCarouselSlider" data-slide="next">

</a>
</div>
If the code doesn't work properly, consider wrapping it in a container div.
