it fixes the issue Don't duplicate your ID. ID should be unique-per-page.
Also, why not do it in pure CSS? (no JS required)
code :
<div class="imgBox">
    <img src="cat.jpg">
    <img src="mask.png">
</div>
<div class="imgBox">
    <img src="bear.jpg">
    <img src="mask.png">
</div>
<div class="imgBox">
    <img src="elephant.jpg">
    <img src="mask.png">
</div>
.imgBox{
  position:relative;
  /*width, height etc... */
}
.imgBox img{
    position:absolute;
    top: 0;
    transition: opacity 0.5s; /* yey! */
}
.imgBox:hover img + img{ /* on hover target the second image */
    opacity: 0;
}

will help you I have looked around for a solution to this problem, but it's so wonky that I doubt many people have considered it. A web application that I've recently inherited as a web administrator runs on Drupal (version 6). Unfortunately, I am unable to edit the Drupal install or create a custom theme until May due to other obligations that must be tended to first. , Use a more specific selector:
code :
$('ul.menu > li.expanded > a').attr( ...

fixed the issue. Will look into that further Here's a simple webpage. Why doesn't the textarea's width change when the browser is resized? , The style.width requires a unit to be set, like px.
code :
document.getElementById("main").style.width=window.innerWidth + "px";

like below fixes the issue I'm working on a problem like this for sometime now, trying to figure out what to do with the indexes. Here's the problem: , You could use a replace with positive lookahead.
code :
var str = "thisIsGreat";
   
str = str.replace(/(?=[A-Z])/g, ' ').split('');
document.write('<pre>' + JSON.stringify(str, 0, 4) + '</pre>');

With these it helps You are constantly resetting your array. You need to initialize it in the outer loop. Change this:
code :
for(let id = 0; id < rainbowelements.length; id++) {
    for(let i = 0; i < rainbowelements[id].length; i++) {
        hovercounters[id] = [];
        hovercounters[id][i] = 0 + i;
    }  
}
for(let id = 0; id < rainbowelements.length; id++) {
   hovercounters[id] = [];
   for(let i = 0; i < rainbowelements[id].length; i++) {
        hovercounters[id].push(i);
    }
}
or (let id = 0; id < rainbowelements.length; id++) {
  hovercounters[id] = rainbowelements[id].map((_, i) => i);
}
let rainbowhover = document.getElementsByClassName('foxrainbowhover');
let rainbowelements = [];
let hoverinterval = [];
let hovercounters = [];

for (let i = 0; i < rainbowhover.length; i++) {
  rainbowelements[i] = spanElementContents(rainbowhover[i]);
}

//Set up the wavy effect with counters.
for (let id = 0; id < rainbowelements.length; id++) {
  hovercounters[id] = rainbowelements[id].map((_, i) => i);
}

// Add event listeners for every item classed foxrainbowhover.
for(let id = 0; id < rainbowhover.length; id++) {
    rainbowhover[id].addEventListener("mouseenter", function startanimation() {
        hoverinterval[id] = setInterval(() => {
            for(let i = 0; i < rainbowelements[id].length; i++) {
                rainbowelements[id][i].style.color = 'hsl(' + (hovercounters[id][i] + Math.floor(i * 1)) + ', 100%, 70%';

                hovercounters[id][i]++;
            }
        }, 8);
    }, false);

    rainbowhover[id].addEventListener("mouseleave", function stopanimation() {
        clearInterval(hoverinterval[id]);
        for(let i = 0; i < rainbowelements[id].length; i++) {
            rainbowelements[id][i].style.color = 'black';
        }
    }, false);
}

function spanElementContents(element) {
  let spans = [];
  let chars = [];

  chars.push(element.innerText.split(""));
  for(let i = 0; i < chars.length; i++){
    element.innerHTML = chars[i].map(function(char) {
      return '<span>' + char + "</span>";
    }).join('');
  }

  let temphtmlcollection = [].slice.call(element.children)
  for(let j = 0; j < temphtmlcollection.length; j++) {
     spans.push(temphtmlcollection[j]);
  }
  return spans;
}
h1 {
  color: black;
}
<h1 class="foxrainbowhover">test1</h1>
<h1 class="foxrainbowhover">test111</h1>
<h1 class="foxrainbowhover">test111111</h1>
