Perspective Style Class Breathing Synchronization

[simeonw]

Other similar posts have discussed the topic, and the general consensus is that you can't do it with CSS only and it is quite involved to implement well with JavaScript.

Perspective Styling animation sync

Is there any way to make the styling animations synchronised across each component that uses them? [UnsyncdAnimation] [UnsyncdAnimation2] And if not possible without custom css now, is this a feasible idea request to add an option to a style class for the animation to be synchronous for all?

However, with some VERY janky JavaScript and @victordcq's Markdown injection method:

Javascript inject in Perspective... have fun

Soo i'll just link this here... You can do whatever with it, but its not really gonna be clean or easy xD Have fun WARNING Dont let userinput enter in here [image]

Create a new markdown component and disable escapeHtml

Then create an expression binding on the source prop containing the style class to target and a script transform with the code below:

def transform(self, value, quality, timestamp):
	code =  """<img style='display:none' src='/favicon.ico' onload=\"	
		var targetNode = document.documentElement;
		var observerConfig = { subtree: true, attributes: true, attributeFilter: ['class'] };
		
		var mutationCallback = function(mutationsList, observer) {
		    mutationsList.forEach(function(mutation) {
		        if (mutation.type === 'attributes' && mutation.attributeName === 'class') {
		            var targetElement = mutation.target;
		            if (targetElement.classList.contains('psc-igStyleClass')) {
		                var elements = document.querySelectorAll('.psc-igStyleClass');
					    elements.forEach(function(element) {
					    	var animation = element.style.animation;
					    	element.style.animation = 'none';
					        void element.offsetWidth;
					        element.style.animation = animation;
					    });		              
		            }
		        }
		    });
		};
		
		var observer = new MutationObserver(mutationCallback);
		observer.observe(targetNode, observerConfig);
	\"></img>""".replace("\n", "").replace("\t", "").replace("igStyleClass",value)
	return code

The code basically setups a mutation observer, that monitors for the animated class being added to an element, then loops through all elements with that class and reset their animations. All animation will be reset to the start, which is not ideal...
