Play sound if div pass a offset while in animation?

Long story short, I used this source, to simulate a case opening: https://codepen.io/zheleznov/pen/POXMdO

I managed to add multiple case openings at once, and other stuffs, but, what I want to add now is that, to play a sound when a div passes a certain offset.
I've tried to check where is the middle position, using offsetLeft, and I got 411.
My question is, can I add sound everytime a div passes that offset?
Or is there any other way to play a sound individually for each div?
(The effect I want to get is this one: https://www.youtube.com/watch?v=9ChsGHLPyG8)

Local storage data not saving on page refresh

I am creating a settings portion on a website. I want the features chosen to be "saved" and kept when the page refreshes. I attempted this but it seems to just reset the form when I refresh the page. Another issue is when I click on the cancel button, the toggle buttons reset but the dropdown comes back blank instead of going back to the placeholder "select timezone". The issue most likely lies in my javascript code below. It's also throwing an error in stack overflow but works properly on my website (minus the issues described above). Any suggestions would be much appreciated!
// ---------- TOGGLE BTN ----------
const toggle = document.getElementsByClassName("toggle");
const labels = document.getElementsByClassName("labels");
for(let i=0; i < 2; i++) {
labels[i].innerHTML = "OFF";
toggle[i].addEventListener( "click", () => {
if(labels[i].innerHTML == "OFF") {
// console.log("button toggled");
labels[i].classList.add("on");
labels[i].innerHTML= "ON";
} else {

labels[i].innerHTML = "OFF";
}

here a working example.
The problems with your code were that you were using emailBtn.value and publicBtn.value instead of emailBtn.checked and publicBtn.checked (they are checkbox so in order to get the correct value you have to read che checked property) and you were not loading the saved values on document load (the function inside window.addEventListener("load", ...) in my example.
Hope this helps you.

The fullscreen is applied to the full window instead rather than just my video. I can see function is working just probably is not the right one.
I would like my actual video (black background) to be in fullscreen instead.

May be this would help you

Transition from right to left

I need to change some background color with a smooth transition from right to left instead of just changing the color in a uniform way. I will now provide you my code, so that maybe it will be more clear.

I am sorry if my explanation appears poor: I'll be happy to answer your doubts.

You could do it very simply with css transition. This method work on :hover. Working CodePen.
HTML
<div>
<p>This is some text</p>
</div>
CSS

background-size: 200% 100%;
background-position: right bottom;
transition: all ease 1s;

How to make the simon game work properly

I'm working on the "Simon Game" project.
I want it to lighten buttons in the proper sequence. But now by far the code works properly until the 2-nd level.
If I am right the checkButton(randIndexArr, counter) should be included to the promise, so that if counter === index then it should call checkButton and maybe there are some more errors that I missed.
Here's a link with the video: How the code should work to be more clear Zipline: Build a Simon Game
and here is my code:
document.addEventListener("DOMContentLoaded", function () {
'use strict';
var checkOn = document.querySelector("input[type=checkbox]");
var gameCount = document.getElementsByClassName("innerCount")[0];
var startButton = document.getElementById("innerStart");
var strictButton = document.getElementById("strictButton");
var strictInd = document.getElementById("strictIndicator");
var strictMode = false;
var soundArray = document.getElementsByTagName("audio");
var buttons = document.querySelectorAll(".bigButton");
var buttonArray = [].slice.call(buttons, 0);
checkOn.addEventListener("change", function () {
if (checkOn.checked) {
gameCount.innerHTML = "--";
} else {
gameCount.innerHTML = "";
}
});
strictButton.addEventListener("click", function () {
strictMode = !strictMode;
strictMode ? strictInd.style.backgroundColor = "#FF0000" :
strictInd.style.backgroundColor = "#850000";
});
function getRandArray() {
var array = [];
for (var i = 0; i < 22; i++) {
array[i] = Math.floor(Math.random() * 4);
}
document.getElementsByClassName("randArray")[0].innerHTML = array;
return array;
}
startButton.addEventListener("click", function () {
var level = 0;
var randIndexArr = getRandArray();
playGame(randIndexArr, level);
});
function sleep(time) {
return new Promise(resolve => {
setTimeout(resolve, time)
})
}
function checkButton(randIndexArr, counter) {
console.log('checkButton');
var checker = function checker(e) {
var clickedButtonId = e.target.dataset.sound;
lightenButton(clickedButtonId);
sleep(1000);
for (let index = 0; index <= counter; index++) {
if (+(clickedButtonId) === randIndexArr[index]) {
if (index === counter) {
console.log('checking passed - next level :', (counter + 1));
counter++;
for (var i = 0; i < 4; i++) {
buttonArray[i].removeEventListener("click", checker, false)
}
playGame(randIndexArr, counter);
}
}
}
}
;
for (var i = 0; i < 4; i++) {
buttonArray[i].addEventListener("click", checker, false)
}
}
function playGame(randIndexArr, counter) {
if (counter === 22) {
return;
}
//Show the level of the Game
gameCount.innerHTML = counter + 1;
//Light and play random buttons according to the level
//Light and play user's input then check if input is correct
randIndexArr.slice(0, counter + 1).reduce(function (promise, div, index) {
return promise.then(function () {
console.log("slice reduce");
lightenButton(div);
return new Promise(function (resolve, reject) {
setTimeout(function () {
resolve("reduce Resolve");
}, 1000);
})
})
}, Promise.resolve()).then(function (value) {
console.log(value);
checkButton(randIndexArr, counter);
});
}
function lightenButton(id) {
var lightColorsArr = ["liteGreen", "liteRed", "liteYell", "liteBlue"];
var promise = new Promise((resolve, reject) => {
soundArray[id].play();
buttonArray[id].classList.add(lightColorsArr[id]);
setTimeout(function () {
resolve("lighten");
}, 500);
});
promise.then(function (value) {
console.log(value);
buttonArray[id].classList.remove(lightColorsArr[id]);
});
}
});

One of the problem (along many others) is in checkButton function itself, where you checking buttons against array, but doesn't check the series of button presses, or "attempts".
For example, if randIndexArr contains values [2,2,1,1...], your code is okay with checking clickeBbuttonId with value 2 against both array's first two values, and so on.
I did rewrote only one function checkButton just to show you one of possible approaches:
var currentAttempt = 1
function checkButton(randIndexArr, counter) {
var checker = function checker(e) {
var clickedButtonId = e.target.dataset.sound;
lightenButton(clickedButtonId);
if (randIndexArr[currentAttempt -1] === +(clickedButtonId)){
if (currentAttempt - 1 === counter) {
counter++
currentAttempt = 1
for (var i = 0; i < 4; i++) {
buttonArray[i].removeEventListener("click", checker, false)
}
playGame(randIndexArr, counter);
}
currentAttempt++
} else {
currentAttempt = 1
}
};
for (var i = 0; i < 4; i++) {
buttonArray[i].addEventListener("click", checker, false)
}
}
But to be honest, whole code should be redesigned.
