Bootstrap 3 Carousel Not Working

My carousel from Bootstrap won't display my images or react to the controls.

This is my HTML:

<!DOCTYPE HTML>
<html>
    <head>
        <title>Skates R Us</title>
        <meta name="viewport" content="width=device-width, initial-scale=1.0">
        <link rel="stylesheet" href="css/bootstrap.min.css">
        <link rel="stylesheet" href="css/global.css">
    </head>

    <body>
        <div class="navbar navbar-inverse navbar-fixed-top" role="navigation">
            <div class="container">
                <div class="navbar-header">
                    <button type="button" class="navbar-toggle" data-toggle="collapse" data-target=".navbar-collapse">
                        <span class="sr-only">Toggle navigation</span>
                        <span class="icon-bar"></span>
                        <span class="icon-bar"></span>
                        <span class="icon-bar"></span>
                    </button>
                    <a href="#" class="navbar-brand">
                        Skates R Us
                    </a>
                </div>
                <div class="collapse navbar-collapse">
                    <ul class="nav navbar-nav">
                        <li class="active">
                            <a href="index.html">Home</a>
                        </li>
                        <li>
                            <a href="contact.html">Contact / About</a>
                        </li>
                        <li>
                            <a href="shop.html">Shop</a>
                        </li>
                        <li>
                            <a href="new.html">New Products</a>
                        </li>
                        <li>
                            <a href="media.html">Media</a>
                        </li>
                    </ul>
                </div>
            </div>
        </div>

        <div id="carousel" class="carousel slide" data-ride="carousel">
            <ol class="carousel-indicators">
                <li data-target="carousel" data-slide-to="0"></li>
                <li data-target="carousel" data-slide-to="1"></li>
                <li data-target="carousel" data-slide-to="2"></li>
            </ol>
            <div class="carousel-inner">
                <div class="item">
                    <img src="img/slide_1.png" alt="Slide 1">
                </div>
                <div class="item">
                    <img src="img/slide_2.png" alt="Slide 2">
                </div>
                <div class="item">
                    <img src="img/slide_3.png" alt="Slide 3">
                </div>
            </div>
            <a href="#carousel" class="left carousel-control" data-slide="prev">
                <span class="glyphicon glyphicon-chevron-left"></span>
            </a>
            <a href="#carousel" class="right carousel-control" data-slide="next">
                <span class="glyphicon glyphicon-chevron-right"></span>
            </a>
        </div>

        <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"></script>
        <script src="js/bootstrap.min.js"></script>
        <script>
            $("#carousel").carousel();
        </script>
    </body>
</html>

My CSS:

#carousel {

    margin-top: 50px;

}

.carousel {
    height: 500px;
    margin-bottom: 60px;
}
/* Since positioning the image, we need to help out the caption */
.carousel-caption {
    z-index: 10;
}

/* Declare heights because of positioning of img element */
.carousel .item {
    width: 100%;
    height: 500px;
    background-color: #777;
}
.carousel-inner > .item > img {
    position: absolute;
    top: 0;
    left: 0;
    min-width: 100%;
    height: 500px;
}

@media (min-width: 768px) {
    .carousel-caption p {
            margin-bottom: 20px;
            font-size: 21px;
            line-height: 1.4;
    }
}

img {
    background: red;
}

There are no errors in the Chrome console and the code is pretty much the exact same as that from the Bootstrap examples.

This is what the site looks like on my end: Site

Recently I was helping a friend to find why their carousel was not working. Controls would not work and images were not transitioning. I had a working sample on a page I had used and we went through all the code including checking the items above in this post. We pasted the "good" carousel into the same page and it still worked. Now, all css and bootstrap files were the same for both. The code was now identical, so all we could try was the images.

So, we replaced the images with two that were working in my sample. It worked. We replaced the two images with the first two that were originally not working, and it worked. We added back each image (all jpegs) one-by-one, and when we got to the seventh image (of 18) and the carousel failed. Weird. We removed this one image and continued to add the remaining images until they were all added and the carousel worked.

for reference, we were using jquery-3.3.1.slim.min.js and bootstrap/4.3.1/js/bootstrap.min.js on this site.

I do not know why an image would or could cause a carousel to malfunction, but it did. I couldn't find a reference to this cause elsewhere either, so I'm posting here for posterity in the hope that it might help someone else when other solutions fail.

Test carousel with limited set of "known-to-be-good" images.

There are just two minor things here.

The first is in the following carousel indicator list items:

<li data-target="carousel" data-slide-to="0"></li>

You need to pass the data-target attribute a selector which means the ID must be prefixed with #. So change them to the following:

<li data-target="#carousel" data-slide-to="0"></li>

Secondly, you need to give the carousel a starting point so both the carousel indicator items and the carousel inner items must have one active class. Like this:

<ol class="carousel-indicators">
    <li data-target="#carousel" data-slide-to="0" class="active"></li>
    <!-- Other Items -->
</ol>
<div class="carousel-inner">
    <div class="item active">
        <img src="https://picsum.photos/1500/600?image=1" alt="Slide 1" />
    </div>
    <!-- Other Items -->
</div>

For me, the carousel wasn't working in the DreamWeaver CC provided the code in the "template" page I am playing with. I needed to add the data-ride="carousel" attribute to the carousel div in order for it to start working. Thanks to Adarsh for his code snippet which highlighted the missing attribute.

Well, Bootstrap Carousel has various parameters to control.

i.e.

Interval: Specifies the delay (in milliseconds) between each slide.

pause: Pauses the carousel from going through the next slide when the mouse pointer enters the carousel, and resumes the sliding when the mouse pointer leaves the carousel.

wrap: Specifies whether the carousel should go through all slides continuously, or stop at the last slide

For your reference:

Hope this will help you :)

Note: This is for the further help.. I mean how can you customise or change default behaviour once carousel is loaded.

Here is the changes you need to be done

just replace the carousel div with the below code

You have missed the '#' for data-target and add active class for the first item

<div id="carousel" class="carousel slide" data-ride="carousel">
            <ol class="carousel-indicators">
                <li data-target="#carousel" data-slide-to="0"></li>
                <li data-target="#carousel" data-slide-to="1"></li>
                <li data-target="#carousel" data-slide-to="2"></li>
            </ol>
            <div class="carousel-inner">
                <div class="item active">
                    <img src="img/slide_1.png" alt="Slide 1">
                </div>
                <div class="item">
                    <img src="img/slide_2.png" alt="Slide 2">
                </div>
                <div class="item">
                    <img src="img/slide_3.png" alt="Slide 3">
                </div>
            </div>
            <a href="#carousel" class="left carousel-control" data-slide="prev">
                <span class="glyphicon glyphicon-chevron-left"></span>
            </a>
            <a href="#carousel" class="right carousel-control" data-slide="next">
                <span class="glyphicon glyphicon-chevron-right"></span>
            </a>
        </div>
