My bootstrap carousel slider is not working

Question

I used the bootstrap carousel slider plugin, but it does not seem to be working. I did modify the bootstrap code a bit using this example: file:///C:/Users/wangsi/Desktop/corlate-free-responsive-business-html-template/index.html

See my example on fiddle: JsFiddle

<section id="main-slider" class="no-margin wow fadeInDown">
        <a class="prev hidden-xs" href="#main-slider" data-slide="prev">
          <i class="fa fa-chevron-left"></i>
        </a>
        <a class="next hidden-xs" href="#main-slider" data-slide="next">
          <i class="fa fa-chevron-right"></i>
        </a>
        <div class="carousel slide" data-ride="carousel">

            <ol class="carousel-indicators">
                <li data-target="#main-slider" data-slide-to="0" class="active"></li>
                <li data-target="#main-slider" data-slide-to="1"></li>
                <li data-target="#main-slider" data-slide-to="2"></li>
            </ol>

          <div class="engineering-section">
            <div class="engineering-section-title title-text text-center">Engineering</div>
              <div class="down-button bounceInDown animated">

Answer 1

JsFiddle

I took a look at your fiddle, it seems everything is fine from my perspective. So I looked into the console and I realised you aren't loading JQuery. You might want to start somewhere there first. Bootstrap Js requires Jquery .

<script src="//ajax.googleapis.com/ajax/libs/jquery/1.9.6/jquery.min.js"></script>

---

Edit: a look at the file you are loading, there is nothing in there that screams JQuery. So I suggest you load JQuery file before you load BootstrapJs.
