Creating a seamless slideshow using HTML

Being a beginner in HTML, CSS, and JavaScript, I am eager to incorporate a smooth slideshow on my website using jQuery or JavaScript. At the moment, my code looks like this, but I am struggling with implementing jQuery.

<div class="col-md-6">
    <div class="story_image wow slideInLeft" data-wow-duration="2s">
         <img src="images/1.jpg" alt="" class="mySlides">
         <img src="images/2.jpg" alt="" class="mySlides">
         <img src="images/3.jpg" alt="" class="mySlides">
         <img src="images/4.jpg" alt="" class="mySlides">
         <img src="images/5.jpg" alt="" class="mySlides">
    </div>
</div>

Here is how I currently use JavaScript:

    var myIndex = 0;
    carousel();

    function carousel() {
    var i;
    var x = document.getElementsByClassName("mySlides");
    for (i = 0; i < x.length; i++) {
         x[i].style.display = "none";  
    }
    myIndex++;
    if (myIndex > x.length) {myIndex = 1}    
    x[myIndex-1].style.display = "block";  
    setTimeout(carousel, 3000); // Change image every 2 seconds
}

To achieve a smooth transition effect, you can utilize the `opacity` property along with CSS transitions. This method involves absolutely positioning the images and adjusting the container's height to match each image during the transition.

var currentIndex = 0,
    parentContainer = document.getElementsByClassName('story_image')[0];

carousel();

function carousel() {
  var index,
      element,
      slides = document.getElementsByClassName("mySlides");
      
  for (index = 0; index < slides.length; index++) {
    slides[index].style.opacity = "0";
  }
  
  currentIndex++;
  
  if (currentIndex > slides.length) {
    currentIndex = 1;
  }
  
  element = slides[currentIndex - 1];
  parentContainer.style.height = element.height + 'px';
  
  setTimeout(function() {
    element.style.opacity = "1";
    setTimeout(carousel, 3000);
  }, 500);
}

.story_image {
  position: relative;
  transition: height .5s;
  background: #eee;
}
.mySlides {
  position: absolute;
  top: 0;
  left: 0;
  transition: opacity .5s;
}

<div class="col-md-6">
    <div class="story_image wow slideInLeft" data-wow-duration="2s">
         <img src="http://kenwheeler.github.io/slick/img/fonz1.png" alt="" class="mySlides">
         <img src="http://www.jqueryscript.net/images/Simplest-Responsive-jQuery-Image-Lightbox-Plugin-simple-lightbox.jpg" alt="" class="mySlides">
         <img src="http://www.jqueryscript.net/images/Dynamic-Horizontal-Vertical-Image-Slider-Plugin-slideBox.jpg" alt="" class="mySlides">
    </div>
</div>

Your code seems to be working perfectly fine, as shown in the example on jsfiddle that was included with your question.
Upon examining the JavaScript code provided in your question, I found no issues that would prevent it from functioning properly.

var myIndex = 0;
    carousel();

    function carousel() {
    var i;
    var x = document.getElementsByClassName("mySlides");
    for (i = 0; i < x.length; i++) {
         x[i].style.display = "none";  
    }
    myIndex++;
    if (myIndex > x.length) {myIndex = 1}    
    x[myIndex-1].style.display = "block";  
    setTimeout(carousel, 3000); // Change image every 2 seconds
}

After testing the code, it performed perfectly as expected.

If you're looking to enhance or optimize your carousel functionality, I suggest checking out the carousel.js script by ksylvest, or exploring the carousel example provided in Bootstrap 3. Both resources offer additional features and improvements that may benefit your project.
