how to create design Letter z with animation in css

I want to create the letter z in animation.
In such a way that the first part (1) appears without delay with animation from left to right.
When the first part (1) reaches the right, the second part (2) will appear from top to bottom with animation.
When the second part (2) is down, the third part (3) will appear from left to right with animation.
The problem with this animation is that all three parts (1-2-3) appear together, while I want them to appear alternately and late.
Thank you in advance for your cooperation.

This snippet thinks of things slightly differently.
Each line has a 3 second animation with the top one animating to its full width in the first second, ie the first 33.33% of the time, the second animating to its full width in the second second and the third in the third second.
That way aspects such as the lines not being visible to start with are dealt with.

How can I implement this loader for my project?

Basically, I am trying to implement a loader for my clock project. However, for some reason, it does not work. I have tried moving my code around to see what's wrong, but I have not figured it out. However, if I remove the div that my clock is in, the loader appears and fades out which is what I want it to do. How can I produce my loader so it appears, fades out, and shows the clock? Any help is appreciated. Here is my code below.
setInterval(setClock, 1000)
const hourHand = document.querySelector('[data-hour-hand]')
const minuteHand = document.querySelector('[data-minute-hand]')
const secondHand = document.querySelector('[data-second-hand]')
function setClock() {
const currentDate = new Date()
const secondsRatio = currentDate.getSeconds() / 60
const minutesRatio = (secondsRatio + currentDate.getMinutes()) / 60
const hoursRatio = (minutesRatio + currentDate.getHours()) / 12
setRotation(secondHand, secondsRatio)
setRotation(minuteHand, minutesRatio)
setRotation(hourHand, hoursRatio)
}
function setRotation(element, rotationRatio){
element.style.setProperty('--rotation', rotationRatio * 360)
}
setClock()

You only need to add Z-index to the parent container of either the Clock or the loader:
Here I add a z-index on the container of the clock:
#section1{
z-index: -1;
}
So the loader and your clock are overlapping on one another and the clock has higher priority in terms of your HTML which is below the loader HTML-markup and that is why the clock shows on top of the Loader.

Content overlapping when display size is too small

I have an issue with my site; I cannot find a way to make my content stop overlapping when the actual display size is smaller than the original display size - 1920x1080.
I would like to know how I could either scale down the whole page or just make my content not overlap.
Thanks in advance for any help provided!

absolute position will cause elements to overlap. Better to use position:relative and display:block to stack elements on the page. Please refer to: https://www.w3schools.com/css/css_positioning.asp
Consider using bootstrap, responsive framework out of the box. Get started by pasting css and js link and you are ready to go:
https://getbootstrap.com/docs/4.3/getting-started/introduction/

Instead of using position: absolute everywhere you should consider to use other approach like :
CSS flex (https://css-tricks.com/snippets/css/a-guide-to-flexbox/)
CSS grid (https://css-tricks.com/snippets/css/complete-guide-grid/)
It's more flexible and responsive.
You also can use other units like viewports units (vw or vh) to use screen size relative units : https://css-tricks.com/fun-viewport-units/

Right now I have a White Background, I would like the Background to be Pure Black. I have tried a few things but nothing seems to work.
I am loading the GIF from a URL.
I know that the color code for Black is #000000 and I have tried entering it instead of the opacity = 0; but nothing seems to work.
Any advice ?

Add this style
html {
height: 100%;
background-color: black;
}

html , body{ height: 100%;}
html {background-color: black;}

CSS animation reset transform

I have a CSS clock, the minute hand has the following animation styling:
animation: a36016 3600s normal infinite steps(3600,end);
This allows it to move along as the minutes go by.
When I load the page the minutes hand has a rotation set like this:
transform:rotate(180deg);
Using setInterval I am trying to reSync it. So for example after 10 minutes if I get the rotation for example as 210deg, and then I change it like this:
$('#clock .mm').css( {'transform': 'rotate(210deg)'});
The problem is that it doesn't actually set the degrees to 210, for some reason it adds to whatever amount of degrees the animation has already moved. So it becomes 210deg plus whatever amount it has already moved.
Can someone tell me how I can adjust the animation styling so this doesnt happen, if change the rotation usig javascript to whatever it is, it should set it to that regardless of how many degrees it has already moved.
Thanks

This removes the value of the CSS property entirely, will that help?
// Reset transform
$('#clock .mm').css({'transform': ''});

This issue is not related to changing transform by jQuery or initial value of transform by CSS.
if you have following example:
<!doctype html>
<html lang="en">
<head>
<title></title>
<!-- Required meta tags -->
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no">
<style>
.a{width: 100px; height:100px; margin: 100px auto; background: #000}
.b{height: 100px; width: 100px;transform:rotate(10deg); background: red;}
</style>
</head>
<body>
<div class="a">
<div class="b">
</div>
</div>
<script src="https://code.jquery.com/jquery-3.2.1.slim.min.js" crossorigin="anonymous"></script>
<script language="javascript">
$('.b').css( {'transform': 'rotate(20deg)'});
</script>
</body>
</html>
You see that it change just 10 degree and even you change $('.b').css( {'transform': 'rotate(10deg)'}); it does not change.
the problem is related to something else or even a logical error.
According to codes that you sent if you change your jQuery to this:
$(document).ready(function(){
function SyncTime(){
$('#clock .hh').css( {'transform': 'rotate(50deg)'});
$('#clock .mm').css( {'transform': 'rotate(50deg)'});
}
setInterval(SyncTime,5000);
});
After 5 seconds it will redirect to a location and never change its position. the calculation time that pass from ajax.php has issue
