Hello,

I have created this JS script code  to let each of letter of text  to animate .

I have first created this HTML CODE:

<h1 class="message-texst">welkom to our website</h1>

This is CSS Code:

 h1{	
color:black;
font-size:2rem;
text-align:center;
line-height:50vh;	
}
	
span {	
	opacity:0;
	transition:all 1s ease;
	
}

span.fade {	
opacity:1;	
	
}

and this is JS CODE:

<script>	
const text=document.querySelector(".message-text");
const strText=text.textContent;
const splitText=strText.split("");
text.textContent= "";
for(let i=0; i < splitText.length; i++)  {
	
	text.innerHTML += "<span>" + splitText[i] + "</span>";
	}

	let char= 0;
	let timer=setInterval(onTick, 50);
	function onTick() {
	const span=text.querySelectorAll("span")[char];
		span.classList.add("fade");
		char++;
		if(char === splitText.length) {
		complete();
			return;		}		
	}

 function complete() {	 
	clearInterval(timer);
	 timer=null;
	 
 }  

</script>

I don't see any clue !  can some one tell me what is the wrong?

the span and fade class are generated in JS code.

thank you very much
