The problem is you are loading your js script before rendering elements on the page.
You can use defer attribute for the script tag to launch script after page rendering.
<script src="js/myscript.js" defer>
getElementsByTagName() is returning a HTMLCollection, so here is a working code:
console.log('test1');
let elemens = document.getElementsByTagName('p');
for (let i=0; i < elemens.length; i++) {
elemens[i].style.color = 'red';
}
console.log(elemens);
And by the way, is it a typo with elemens variable up above?

Wrap Javascript code in DOMContentLoaded event
Like
document.addEventListener("DOMContentLoaded", function(event) {
//do work
});
More information
https://developer.mozilla.org/en-US/docs/Web/API/GlobalEventHandlers/onload
document.addEventListener("DOMContentLoaded", function(event) {
console.log('test1')
let elemens = document.getElementsByTagName('p');
for (let i = 0; i < elemens.length; i++) {
elemens[i].style.color = 'red';
}
});

You are loading the script tag in the Head without any delay. So when the page loads, it loads JS first then the body of the Page. I will suggest calling it after the body so that the whole page loads first and after that, the JS loads so that it can have access to the DOM otherwise it will not find any object. That is why it is not working. Load it like this:
</body>
<script src="name.js"></script>
</html>
After the body tag and it should work just fine.

This is mostly because your javaScript is loading before the completely loading of DOM.
there is two Way you can Solve this
1st By wrapping you js code with
window.onload = function() {
// Your code
}
2nd By placing your Script tag after body.
</body>
<script src="name.js"></script>
</html>

Links in my hamburger menu detach themselves from navbar while scrolling down

I'm having this issue where I have a navbar and a hamburger menu which displays some links on click.
The links are fixed positioned, and body is set to overflow-x: hidden and overflow-y: scroll, but when I try to scroll down the page in mobile, it doesn't work; whereas the whole thing scrolls down too if I remove the overflow-x attribute.
I just need to find the way to make the page scroll when the menu is closed and to not do it and not detach from the navbar while it's open. I had to set the overflow-x: hidden because in mobile it scrolled to the right where the nav-links were hidden.
const navSlide = () => {
const burger = document.querySelector('.burger');
const nav = document.querySelector('.nav-links');
const menu = document.querySelector('.menu');
const navLinks = document.querySelectorAll('.nav-links li');
burger.addEventListener('click', () => {
nav.classList.toggle('nav-active');
navLinks.forEach((link, index) => {
if (link.style.animation) {
link.style.animation = '';
} else {
link.style.animation = `navLinkFade 0.3s ease-in forwards ${index/7+.5}s`;
}
});
burger.classList.toggle('toggle');
});
}
navSlide();

I got it working. Change the nav-links position from fixed to absolute.
.nav-links {
z-index: 100;
position: absolute;
right: 0;
height: 90vh;
top: 10vh;
display: flex;
flex-direction: column;
align-items: center;
width: 60%;
background-color: #f4f8ff;
transform: translateX(100%);
transition: transform 0.5s ease-in;
}

When I put data-aos="zoom-in" inside the content of modal become doesn't work, but it works with the photo button.
Any idea for this?

Using Window.resize and media queries to move a div element

demo image I am using the window resize function to check the width of my page, if it's below 891, I fire the function to move my #formWrapper div to #formbottom on the page, the media query is set to max width 891 to change the formWrapper to float left, and have a max-width of 100%. Everything is almost working properly but there is a slight jump, when the browser reaches 891px, it seems like the media query and the JS function are slightly off?
You can see this by resizing the browser window. Any insight would be greatly appreciated.
$(document).ready(function() {
$(window).resize(function() {
if ($(window).width() < 891) {
$("#formWrapper").detach().appendTo('#formbottom');
} else {
if ($(window).width() > 891) {
$("#formWrapper").detach().appendTo('#formtop');
}
}
});
});
