Why do my Elements have this weird offset?

Hello Stackoverflow Users, so I am making a game with HTML, I have to eat berries, but when I collect them, the more I collect (the max is 5), the more offset the extra body parts add to all of the body parts (minus the main one).
I have tried changing offset with the variables and loop I used, but nothing worked, no matter the math operator.
All of jQuery code:
// Null Variables \\
/* These variables have no value. */
var bound;
var newFood;
var horizontalMatch;
var vertialMatch;
// Main Variables \\
/* These variables keep values in store. */
var background = $(".game-background");
var player = $(".game-player");
var verticalNum = 0;
var horizontalNum = 0;
var score = 0;
var speed = 20;
var updatePos = 0;
var numOfSnakes = 0;
var snakesArray = [];
// Main Functions \\
/* These are all of the function being called, and created. */
updateSnakeCSS = function (snakes) {
if (snakes.length > -1) {
//for (var i = 0; i < snakes.length; i++) {
console.log(snakes[numOfSnakes - 1]);
$("." + snakes[numOfSnakes - 1]).css("position", "absolute");
$("." + snakes[numOfSnakes - 1]).css("left", player.offset().left - 20);
$("." + snakes[numOfSnakes - 1]).css("top", player.offset().top);
$("." + snakes[numOfSnakes - 1]).css("border", "black");
$("." + snakes[numOfSnakes - 1]).css("border-style", "outset");
$("." + snakes[numOfSnakes - 1]).css("border-width", 2 + "px");
$("." + snakes[numOfSnakes - 1]).css("width", player.width());
$("." + snakes[numOfSnakes - 1]).css("height", player.height());
$("." + snakes[numOfSnakes - 1]).css("background-color", "red");
//}
}
};
addSnake = function (snakes) {
if (numOfSnakes < 5) {
var body = document.getElementsByTagName("body")[0];

It's because of:
speed += 2;
Remove it and it will work fine.
As you're using speed in calculating the verticalNum and horizontalNum everytime, so it increments it with 2 each time, giving a wrong position.
The output after removing it:

Stop the audio player

I have an audio script with play/pause, I want to make the audio stop when I click on the square button at the left, and to add the timing to the right

You can simply use AudioElement.pause() to pause an running element, and the next AudioElement.play() will start from where you left off.
You can essentially set the currentTime property of the audio element to start from the beginning
A simple demonstration of how it works
const pause = document.getElementById('pause');
const stop = document.getElementById('stop');
const play = document.getElementById('play');
const container = document.getElementById('player');
const duration = document.getElementById('duration');
const audio = new Audio('https://www.siriusxm.com/content/dam/sxm-com/audio/test/audio-previews/audio_test03.mp3.png');
let played = 0;
let playing = true;
const wait = (ms) => new Promise(resolve => setTimeout(resolve, ms));
run = async function () {
while(playing) {
if (played == Math.floor(audio.duration)) break;
duration.innerText = `${played} / ${Math.floor(audio.duration)}`;
played++;
await wait(1000);
}
}
container.appendChild(audio);
stop.addEventListener('click', () => {
duration.innerText = `0 / ${Math.floor(audio.duration)}`
audio.pause();
audio.currentTime = 0;
played = 0;
playing = false;
});
pause.addEventListener('click', () => {
audio.pause();
playing = false;
});
play.addEventListener('click', () => {
playing = true
audio.play();
run();
});

**UPDATE
Here my fiddle link

The file list of HTML5 file input is readonly, so when trying to remove a file from it you won't be allowed.
What you need to do is maintain a separate array list (JSON array as per the example).
I have wrapped your X button with a div that hold the file index concatenated to a 'file_' string, and added an onclick function removeLine(obj) that accepts the element as an object.
I have also added a JSON array finalFiles in the global scope as well as moved the inputFile to the global scope.
When the file input changes, I am setting the JSON array with the selected files through :
$.each(this.files,function(idx,elm){
finalFiles[idx]=elm;
});
The function removeLine will flush the input file list to allow the same file selection again if the user removed the file by mistake, the function obtains the file index from the wrapper division id, removes the wrapper div then deletes the file from the JSON array.
function removeLine(obj)
{
inputFile.val('');
var jqObj = $(obj);
var container = jqObj.closest('div');
var index = container.attr("id").split('_')[1];
container.remove();
delete finalFiles[index];
//console.log(finalFiles);
}
You can the maintain your files when the form submits and send them through AJAX post using FormData in a similar manner to This Article.

I've done this before for my Dropzone. Feel free to adjust. This is from my Laravel app. You should focus on avatar_refresh_upload. Cut off unnecessary stuff and you're done.
function avatar_refresh_upload() {
var input = $('input#avatar[type=file]');
input.replaceWith(input.val('').clone(true));
$('#selected_file').html('{{ Lang::get('app.profile_avatar_select') }}');
$('#avatar_refresh_upload').removeAttr('style');
}
$(document).ready(function ($) {
$('input:file#avatar').change(function () {
var file_name = $(this).val();
if (file_name.length > 10) {
file_name = file_name.substring(0, 10) + '...';
}
$('#selected_file').html('File "' + file_name + '" chosen');
$('#avatar_refresh_upload').css('display', 'inline-block');
});
$('#avatar_refresh_upload').on('click', function () {
avatar_refresh_upload();
});
#if ($user->avatar != '')
$('#remove_avatar').change(function () {
if ($(this).is(':checked')) {
avatar_refresh_upload();
$('#avatar').prop('disabled', true);
$('#avatar_preview').css('opacity', '0.5');
$('#avatar_upload_form_area').css('opacity', '0.5');
$('#remove_avatar_info').show();
} else {
$('#avatar').prop('disabled', false);
$('#avatar_preview').removeAttr('style');
$('#avatar_upload_form_area').removeAttr('style');
$('#remove_avatar_info').removeAttr('style');
}
});
#endif
});
Making long story short - if you want to reset input file after you picked a file for upload but before submitting, you have to run:
input.replaceWith(input.val('').clone(true));

Since we cannot modify the selected files array in the <input type'file' multiple> tag then I have updated you code to show the count of file and to delete all the files if multiple files are selected.
There is a fiddle of the updated code.

Trouble with Cloud-Zoom. Zoom box doesnt follow cursor and doesnt span the image

Here is a link to the website so that you can visualize the error im expressing in my title:
https://glassesled.com/aubrey
If you hover over the picture the zoom box doesn't follow the cursor and when you go the lower portions of the image the zoom box reaches a wall. Here are the relevant files (the ones I think are relevant)

stopping setTimeout loop in my snake game?

I've created a snake game, and when the snake hit the wall or itself, it still wont stop moving. I figured out if I used the clearTimeout(), it would help. but it didn't.
Is there a way to stop the loop? or it is another issue?
jQuery(document).ready(function($) {

function init() {
board.initBoard();
drawSnake();

moveSnake();
getSnakeDir();
}

clearTimeout(move);

}

init();
play();
}

for (var i = 0; i < board.DIM; i++) {
var row = $('<div class="row-' + i + '"></div>');
for (var j = 0; j < board.DIM; j++) {
var col = ('<div class="col-' + j + '-' + i + '"></div>');
$(row).append(col);
}
$("#gameboard").append(row);
}
}
}
var snake = {

There were a few problems, but here is the 'working version' (there are more bugs).
1) I renamed drawSnake to createSnake. You weren't fully reinitializing the snake when you called init(). The snakes position was not being reset in the previous drawSnake method, so it would seem like the game was not playable.
After that there were 2 more bugs.
2) You have to return after you call gameOver or the game never really ends does it? Once you clear the timeout in gameover, you immediately set another Timeout for on the last line of moveSnake() because you didn't return once the game was over. That lead to weird results that made it seem like the game was unresponsive.
3) You were using a combination of visibility none or visible and $.hide(). $.hide() uses display: none, so when you tried to show it again with the visibility style change, its still display: none so the new game button would stop appearing.
My advice to any game coder is to learn how to separate the code that handles how the game works (logic of the game, how the clock ticks, initialization of game state, etc) , and how it is displayed (the html and css). Modeling the game logic after a cleanly written system is easy to read and debug. The code becomes harder to understand and modify when the display code is mixed in with game logic. In theory, our game should work perfectly without any kind of rendering. Then we could write a renderer that produces an HTML canvas, html DOM, text in the command line, or OpenGL.
Heres an old project I never finished that should illustrate a separation between model and view.

You could try not to initiate a new setTimeout call at the and of the moveSnake function, but instead using.
function play() {
$('.newGame').css('visibility', 'hidden');
$('.playgame').css('visibility', 'hidden');
move = setInterval(moveSnake, 200);
getSnakeDir();
}
and remove the
move = setTimeout(moveSnake, 200)
from the moveSnake function and do
function gameover() {
clearInterval(move);
$('.newGame').css('visibility', 'visible');
}
