Disable transparency on images in the Materialize carousel layout

I am currently using a 3d carousel that involves displaying images with some opacity. However, I would like to remove the opacity effect on the images.

    $('.carousel').carousel({
            dist:0,
            shift:0,
            padding:20, 
           interval:100
      });

<link href="https://cdnjs.cloudflare.com/ajax/libs/materialize/0.97.6/css/materialize.min.css" rel="stylesheet" type="text/css">
   
<script src="https://cdnjs.cloudflare.com/ajax/libs/materialize/0.97.6/js/materialize.min.js"></script>


 <div class="carousel">
    <a class="carousel-item" href="#one!"><img src="http://lorempixel.com/250/250/nature/1"></a>
    <a class="carousel-item" href="#two!"><img src="http://lorempixel.com/250/250/nature/2"></a>
    <a class="carousel-item" href="#three!"><img src="http://lorempixel.com/250/250/nature/3"></a>
    <a class="carousel-item" href="#four!"><img src="http://lorempixel.com/250/250/nature/4"></a>


    <a class="carousel-item" href="#five!"><img src="http://lorempixel.com/250/250/nature/5"></a>

</div>

I am seeking a way to eliminate the opacity from all of the images being displayed within the carousel.

Answer №1

To adjust the opacity of images in the carousel plugin, you will need to utilize CSS styles as there is no direct option for it. While not ideal, this workaround should do the trick :)

$('.carousel').carousel({
  dist: 0,
  shift: 0,
  padding: 20,
  interval: 100
});

.carousel .carousel-item {
  opacity: 1 !important;
}

Answer №2

Upon exploring different solutions:

.carousel .carousel-item {
  opacity: 1 !important;
}

The initial approach did not meet my requirement of displaying 3 Images in the carousel without any opacity.

An alternative answer provided proved to be complex and challenging to modify further.

Finally, I devised a unique solution by utilizing MutationObserver to monitor attribute changes on the parent .carousel div element.

$(document).ready(function () {

    $('.carousel').carousel({
        'numVisible': 3
    });

    var targetNode = document.querySelectorAll(".carousel")[0];

    // Options for the observer (which mutations to observe)
    var config = { attributes: true, childList: true, subtree: true };

    // Callback function to execute when mutations are observed
    var callback = function(mutationsList, observer) {
        // Use traditional 'for loops' for IE 11
        for(let mutation of mutationsList) {
            if (mutation.type === 'childList') {
                console.log('A child node has been added or removed.');
            }
            else if (mutation.type === 'attributes') {
                console.log('The ' + mutation.attributeName + ' attribute was modified.');
            }
            displayTopThreeImages();
        }
    };

    // Create an observer instance linked to the callback function
    var observer = new MutationObserver(callback);

    // Start observing the target node for configured mutations
    observer.observe(targetNode, config);

    function displayTopThreeImages() {
        [...document.querySelectorAll(".carousel-item")].forEach(item=>{item.style.opacity = item.style.opacity > 0 ? 1 : item.style.opacity});
    }
})

After noticing that the default opacity transition behavior of Materialize Carousel wasn't to my liking, I delved into the code and made some modifications to the _scroll function. Hopefully, this altered solution will be beneficial to others as well. Simply insert the following code snippet before initializing the Carousel:

M.Carousel.prototype._scroll = function(x) {
// Updated scroll function logic goes here
...
};

// Initialize the carousel after making the necessary changes
