Set Concentric Circles Within a Text-box

I am trying to keep these two circles concentric but not have them interfere with the text and stuff on the web page. I am currently using position: fixed, but I want them within a textbox below that can also limit the size of the circles so that they don't take up the whole screen if user inputs something unreasonable value.
*EDIT:
I am now trying to make it so that when an input value of 85 or greater is inputted into outer diameter on jsFiddle or "Pipe O.D." on the actual web page, an error message/some time of message pops up saying "Too big".
Additionally, on the web page itself, there is a calculator button using Formidable Forms. After hitting calculate, it displays the output calculated values, but when the values of the inputs are changed, the circles no longer change size until the page is refreshed. Why is this and how do I fix it?

$(function() {
$('.circle').hide();
$('#outer_diameter').on('change', function() {
var $outer_diameter = parseFloat($("#outer_diameter").val()).toFixed(3);
var $converted = ($outer_diameter * 10).toFixed(3);
console.log($outer_diameter, $converted);
$('.circle').css({

$('.circle').fadeIn(300);
$('.circles').css({height:(2 * $converted) + 10, width: (2 * $converted) + 10})
$('#error').hide();
})
https://jsfiddle.net/p4w6gzov/7/
Basically
I added in the css:
position:relative to the .circles
and position:absolute to the .circle and .circle2
And for the js, I added:
$('.circles').css({height:(2 * $converted) + 10, width: (2 * $converted) + 10})
finally, to limit the use (as for the size), you just need to add a small condition in the change event and if the input is too big, just do nothing and notify the user.
Hope this helped

Background reveal javascript not working properly

By following this tutorial :https://codepen.io/xaviDDB/pen/ExaKeeN I made a section in my website with this background reveal. here is the link:http://example.com/abra/
The code works fine if I do not have any other section in this page. But if I do, then it gets very strange. The reveal circle move away from the Mouse. See the page, I have added a horse image & the code gets messy. How do I solve this?
This is my current code:
(function() {
let magic = document.querySelector('.magic');
let magicWHalf = magic.offsetWidth / 2;
document.body.addEventListener('mousemove', function(e) {
magic.style.left = e.pageX - magicWHalf + 'px';
magic.style.top = e.pageY - magicWHalf + 'px';
});
document.body.addEventListener('mouseout', function(e) {
//magic.style.left = 'calc(50% - 10rem)';
//magic.style.top = 'calc(50% - 10rem)';
});
})();
.containers {
position: relative;
height: 100vh;
width: 100%;
background-color: #ffffff;
text-align: center;
overflow: hidden;
z-index: 1;
}
.containers:hover {
cursor: crosshair;
}
.text {
position: absolute;
font-size: 72px;
font-family: Arial, Helvetica, sans-serif;
color: #000000;
bottom: 20%;
left: 0;
right: 0;
z-index: 3;
}
.magic {
position: absolute;
top: calc(50% - 10rem);
left: calc(50% - 10rem);
width: 500px;
height: 500px;
background: center center no-repeat fixed;
background-size: cover;
border-radius: 50%;
z-index: 2;
}
<div class="containers">
<div class="text">Lorem Ipsum</div>
<div class="magic" style="background-image: url('https://s3-us-west-2.amazonaws.com/s.cdpn.io/142996/hover-reveal.jpg')"></div>
</div>

You have to update your mouse-move function in javascript. It has to calculate the relative mouse position to its parent (.container)
and one more improvement: set the eventListener on the element you want to hover. Not the entire body.
(function() {
const container = document.querySelector('.container');
const magic = document.querySelector('.magic');
const magicWHalf = magic.offsetWidth / 2;
container.addEventListener('mousemove',function(e){
const rect = container.getBoundingClientRect(),
scrollLeft = window.pageXOffset || document.documentElement.scrollLeft,
scrollTop = window.pageYOffset || document.documentElement.scrollTop;
magic.style.left = (e.pageX - (rect.left + scrollLeft)) - magicWHalf+'px';
magic.style.top = (e.pageY - (rect.top + scrollTop)) - magicWHalf+'px';
});
container.addEventListener('mouseout',function(e){
//magic.style.left = 'calc(50% - 10rem)';
//magic.style.top = 'calc(50% - 10rem)';
});
})();
.container {
position: relative;
height: 100vh;
width: 100%;
background-color: #ffffff;
text-align: center;
overflow: hidden;
z-index: 1;
}
.container:hover {
cursor: crosshair;
}
.text {
position: absolute;
font-size: 72px;
font-family: Arial, Helvetica, sans-serif;
color: #000000;
bottom: 20%;
left: 0;
right: 0;
z-index: 3;
}
.magic {
--size: 20rem;
position: absolute;
top: calc(50% - var(--size));
left: calc(50% - var(--size));
width: var(--size);
height: var(--size);
background: center no-repeat fixed;
background-size: cover;
border-radius: 50%;
z-index: 2;
}
<h1>add</h1>

<div class="magic" style="background-image: url('https://s3-us-west-2.amazonaws.com/s.cdpn.io/142996/hover-reveal.jpg')"></div>
</div>

You need to add the height of the previous element of your div.container
html
<div class="other">Other div </div>
<div class="container">
<div class="text">Lorem Ipsum</div>
<div class="magic" style="background-image: url('https://s3-us-west-2.amazonaws.com/s.cdpn.io/142996/hover-reveal.jpg')"></div>
</div>
js
let magic = document.querySelector('.magic');
let magicWHalf = magic.offsetWidth / 2;
let heightPrevELm=document.querySelector('.other').offsetHeight;
document.body.addEventListener('mousemove',function(e){
magic.style.left = e.pageX - magicWHalf+'px';
magic.style.top = e.pageY - (magicWHalf+heightPrevELm)+'px';
});
You can see the result here :

But i think if they are multiple element before we need to optimize the code

Website code works fine on Chrome and Firefox, desktop or mobile, but does not work on Safari

A certain piece of my website works fine on Chrome and Firefox, but does not seem to work on Safari. I checked and all the people trying the website on iPhones had Javascript enabled. Is there something about my code that cannot be read by Safari? Are there any tools out there to test how code would be perceived on Safari that I can use with a windows computer?
Below is the code to the piece of my website. I had to replace all images and text with different content because I am forbidden to share the actual content. Essentially, this piece of the website would allow someone to input a certain metric in, via a slider bar, and see what something would look like with said metric. The slider bar seems to be movable, but images are not appearing, nor are they moving when viewing through Safari. As an additional note, I converted this code to https (what Wix refers to as all in one text block) and inserted it into my Wix website as an html element.
I realize that my JavaScript has quite a few redundancies, such as defining the same variable locally twice instead of defining it globally once. I'm looking to fix those later and get this working first (although this could be why it doesn't work on Safari?). I've never developed anything before, so any help at all would be much appreciated.
Update: I had a few people send me screenshots and the slider bar AND javascript are working, the images are just not showing up on Safari.

Why does device orientation javascript mess up my element positioning?

So I've got my site more or less responsive. Everything stays centered and nice sizes when full screen desktop or mobile. But when I try to incorporate some device orientation javascript everything goes haywire. I'm sure it's something obvious that I'm missing since I'm a newbie but any insights would be appreciated :) Sorry in advance for the mess (been trying many different things without success and still getting my bearings with everything).

Parallax Issue in Javascript

I was creating a parallax effect in which the image and the text move in opposite direction to the movement of the mouse. That is happening inside an element called parallax-wrapper. But when I move out of the element I want the image and the text to return back to their original positions. I have tried to detect the mouse position outside the element but for some reason it not firing properly.

$(".parallax-wrapper").mousemove(function(e) {
var x = e.pageX - $(this).offset().left - $(this).width() / 2;
var y = e.pageY - $(this).offset().top - $(this).height() / 2;
$("*[data-mouse-parallax]").each(function() {
var factor = parseFloat($(this).data("mouse-parallax"));
x = -x * factor;
y = -y * factor;
$(this).css({ transform: "translate3d( " + x + "px, " + y + "px, 0 )" });
});
});
$(document).mouseleave(function(e) {
var target = $(e.target);
if( !target.is("div.layer")) {

What I want is when the mouse is outside the parallax-wrapper the Image and the text return back to their original positions.

You're not resetting the transformations when your mouse leaves. You need to add this where you have the alert...
$(".parallax-wrapper").mouseleave(function(e) {
$("*[data-mouse-parallax]").each(function() {
$(this).css({ transform: "translate3d( 0, 0, 0 )" });
});
});
Note that the mouseleave event is triggered when the mouse leaves .parallax-wrapper, not document as you previously had it.
Here's a modified codepen...

I think a selector was wrong. Here's a correct version or see code below.
To show better when you are inside/outside I change the background color, that's better than an alert. When you leave the wrapper (the black background) it flips correctly now.
Where RED is set you can reset the transform to the origin.
// Trying to replicate the effect here - https://tympanus.net/Development/MorphingBackgroundShapes/
$(".parallax-wrapper").mousemove(function(e) {
var x = e.pageX - $(this).offset().left - $(this).width() / 2;
var y = e.pageY - $(this).offset().top - $(this).height() / 2;
$(".parallax-wrapper").css("background-color", "#00ff00"); // <-- EXIT
// reset transform here
$("*[data-mouse-parallax]").each(function() {
var factor = parseFloat($(this).data("mouse-parallax"));
x = -x * factor;
y = -y * factor;
$(this).css({ transform: "translate3d( " + x + "px, " + y + "px, 0 )" });
});
});
// this is the selector I changed from "document" to ".parallax-wrapper"
$(".parallax-wrapper").mouseleave(function(e) {
var target = $(e.target);
if( !target.is("div.layer")) {
$(".parallax-wrapper").css("background-color", "#ff0000"); // <-- ENTER
e.stopPropagation();

Replace $(document).mouseleave with $(".parallax-wrapper").mouseleave.
$(".parallax-wrapper").mousemove(function(e) {
var x = e.pageX - $(this).offset().left - $(this).width() / 2;
