    Hello

    I can’t make it so I ask help please.
    How can I make a fadein entrance of the featured image on a single page of my blog please ?
    I would like that the .single .attachment-full appears slowly with a fadein effect …

    Thank you

    Hi there,

    can you provide a link to your site so i can see the markup – as there a few custom ways of doing this.

    You can edit your Profiles biography by clicking the Forum Profile button at the top of this page and then clicking Edit.

    Hi,

    Can you explain a bit more on how it will behave? Does the animation have to repeat when the element is not visible within the viewport?

    Usually, you’ll to write a script that checks if the element is in viewport and add an if condition that toggles fade-in class.

    You can use this discussion as a reference:
    https://stackoverflow.com/questions/123999/how-can-i-tell-if-a-dom-element-is-visible-in-the-current-viewport/7557433#7557433

    Alternatively, you can use well-known animate libraries like AOS:

    You can implement AOS on your site and try to animate your targets w/ only unique CSS selector classes using this snippet:

    This is somewhat out of our scope but to help you out, Try this:

    Add animated class to the image you want to animate.

    You then insert this script on your wp_footer.

    var el = document.querySelector('.animated');
    
    function isElementInViewport (el) {
    
        var rect = el.getBoundingClientRect();
    
        return (
            rect.top >= 0 &&
            rect.left >= 0 &&
            rect.bottom <= (window.innerHeight || document.documentElement.clientHeight) && /* or $(window).height() */
            rect.right <= (window.innerWidth || document.documentElement.clientWidth) /* or $(window).width() */
        );
    }
    
    function onVisibilityChange(el, callback) {
        var old_visible;
        return function () {
            var visible = isElementInViewport(el);
            if (visible != old_visible) {
                old_visible = visible;
                if (typeof callback == 'function') {
                    callback();
                }
            }
        }
    }
    
    var handler = onVisibilityChange(el, function() {
    	if(isElementInViewport(el)){
    		if(!el.classList.contains('fade-in')){
    			el.classList.add('fade-in');
    		}else{
    			return;
    		}
    	} if(!isElementInViewport(el)) {
    		if(el.classList.contains('fade-in')){
    			el.classList.remove('fade-in');
    		}else{
    			return;
    		}
    	}
    });
    
    if (window.addEventListener) {
        addEventListener('DOMContentLoaded', handler, false);
        addEventListener('load', handler, false);
        addEventListener('scroll', handler, false);
        addEventListener('resize', handler, false);
    } else if (window.attachEvent)  {
        attachEvent('onDOMContentLoaded', handler); // Internet Explorer 9+ :(
        attachEvent('onload', handler);
        attachEvent('onscroll', handler);
        attachEvent('onresize', handler);
    }

    Ok I found a solution ! I just put this piece of css in the cuqstom css and I works fine …
    Here it is :

    .page-header-image-single {
    animation: fadeIn ease 5s;
    -webkit-animation: fadeIn ease 5s;
    -moz-animation: fadeIn ease 5s;
    -o-animation: fadeIn ease 5s;
    -ms-animation: fadeIn ease 5s;
    }

    @keyframes fadeIn{
    0% {
    opacity:0;
    }
    100% {
    opacity:1;
    }
    }

    @-moz-keyframes fadeIn {
    0% {
    opacity:0;
    }
    100% {
    opacity:1;
    }
    }

    @-webkit-keyframes fadeIn {
    0% {
    opacity:0;
    }
    100% {
    opacity:1;
    }
    }
