How to fix my header getting cut off on mobile browsers?

I need help with fixing my header I can not find the problem! At the beginning it looks fine but when you scroll down it cuts part of it off. But when you scroll back up it goes normal. I think it is with the hamburger menu because when you click on it, it increases the cut off. Here is the link to the website. https://perfectparadox8400.000webhostapp.com/ and here is a gif of what happens!
Link to the picture of what happens!
I only happens when you are on a phone. I used the inspector tools to test it and I did try it on a phone to.
Here is the header code.
<header id="headerrr" class="fixed-top lode">

These are the parts with the header involved!
Please help!
I tried removing the javascript but it did not help!

You adding the on scroll shrink effect to the header
There is two ways to solve this
removing header-scrolled css or change the height of header-scrolled to according to main height mentioned in headerrr css
#headerrr.header-scrolledd {
height: 60px;
transition: all 0.5s;
}
The main height of the header is 80px you adding the header-scrolledcss onscroll in javascript the header-scrolled height of is 66px so when you scroll down the screen get shrink so change the height of header-scrolled to 80px to avoid shrink
second way is to remove the javascript for header
// Header scroll class
$(window).scroll(function() {
if ($(this).scrollTop() > 100) {
$('.header').addClass('header-scrolled');
$('#headerrr').addClass('header-scrolledd');
$('#headerr').addClass('header-scrolleddd');
} else {
$('.header').removeClass('header-scrolled');
$('#headerrr').removeClass('header-scrolledd');
$('#headerr').removeClass('header-scrolleddd');
}
});
if ($(window).scrollTop() > 100) {
$('.header').addClass('header-scrolled');
$('#headerrr').addClass('header-scrolledd');
$('#headerr').addClass('header-scrolleddd');
}
remove this code block it will remove the onscroll function for header removig this will leads to your header will not shrink on scroll
you can choose any one way
my suggestion to remove both header-scrolled and javascript code

I added this: html, body {width: auto!important; overflow-x: hidden!important} and it fixed the problem.

target .class:after:hover in jQuery

I need to target this :after in jQuery:
.a1 {
position: relative;
}
.a1:after {
content: '';
position: absolute;
width: 0;
height: 3px;
display: block;
margin-top: 5px;
right: 0;
background: #3f92c3;
transition: width .4s linear;
-webkit-transition: width .4s linear;
}
.a1:hover:after {
width: 100%;
left: 0;
background: #3f92c3;
}
The scroll code looks like this (example):
$(function() {
var header = $("#header");
$(window).scroll(function() {
var scroll = $(window).scrollTop();
if (scroll >= 100) {
header.addClass("scrolled");
} else {}
});
});
HTML:
<li><a class="a1" href="#">Portfolio</a></li>
<li><a class="a1" href="#">Services</a></li>
<li><a class="a1" href="#">Contact</a></li>
I found this out after searching alot and it worked byt i don't know how the underline can keep the hover color after i mouseleave .a1 :
$('#menuwrapper').mouseenter(function() {
if ($('#pseudo').length) {
$('#pseudo').remove();
} else {
var css = '<style id="pseudo">.a1::after{background: red !important;}</style>';
document.head.insertAdjacentHTML('beforeEnd', css);
};
});
I tried mouseleave but it didn't work.
So i just want that if i scroll (that i know how it works) that the underline under the menu .a1 stay's black , because if i leave the underline hover it goes back to
.a1:after {
background: #3f92c3;
}
I want it to stay black.

pseudo elements like :before and :after are not the part of DOM because they are not real elements as called pseudo...so you can't target them using jQuery
As you are adding class scrolled on scroll, so better to use this class in css like
.scrolled .a1:after{
background: black;
}
$(function() {
var header = $("#header");
$(window).scroll(function() {
var scroll = $(window).scrollTop();
if (scroll >= 100) {
header.addClass("scrolled");
} else {
header.removeClass("scrolled");
}
});
});
body {
margin-top: 150px;
font: 13px Verdana;
height: 500px
}
#header {
list-style: none;
padding: 0;
display: flex;
}
#header li {
margin: 0 10px;
}
.a1 {
position: relative;
font-weight: bold;
text-decoration: none;
}
.a1:after {
content: '';
position: absolute;
width: 0;
height: 3px;
display: block;
margin-top: 5px;
right: 0;
background: #3f92c3;
transition: width .4s linear;
-webkit-transition: width .4s linear;
}
.a1:hover:after {
width: 100%;
left: 0;
}
.scrolled .a1:after {
background: red;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<ul id="header">
<li><a class="a1" href="#">Portfolio</a></li>
<li><a class="a1" href="#">Services</a></li>
<li><a class="a1" href="#">Contact</a></li>
</ul>

try to use jQuery hover method, but also you cant touch :after :before elements from jQuery
$("p").hover(function(){
$(this).css("background-color", "yellow");
}, function(){
$(this).css("background-color", "pink");});

Button is not displaying in FireFox

I am using a button that triggers 4-5 other buttons with animation. its working fine in Chrome but not in FireFox

overflow hidden auto-scroll

Anyone know how can I set auto-scroll (with loop) in div with overflow:hidden; ?
Example
<div class="container" style="width:500px; max-width:500px; height:100px; max-height:100px; background:#F00; overflow:hidden;">
<div class="element_01" style="width:500px; height:100px; float:left;"></div>
<div class="element_02" style="width:500px; height:100px; float:left;"></div>
</div>
final effect?
Show element_01 -> wait 5 sec -> smooth scroll to element_02 -> wait 5 sec // and repeat

This example uses positioning instead of scrolling.
Scrolling with an overflow hidden element works, but can be buggy.

You can use scrollTo jQuery plugin:
http://demos.flesler.com/jquery/scrollTo/
and repeat a function using setTimeout(function(){ $.scrollTo('#element'); }, 5000);

With core javascript:
<div class="container" style="width:500px; max-width:500px; height:100px; max-height:100px; background:#F00; overflow:hidden;">
<div class="element_01" style="width:500px; height:100px; float:left;">aaa</div>
<div class="element_02" style="width:500px; height:100px; float:left;">bbb</div>
</div>
<script>
var container=document.getElementsByClassName('container')[0];
var start = 0;
var smoothVal = 20;
var waitVal = 5000;
function smooth(){
var interval=setInterval(function(){
start++;
container.scrollTop = start;
if(start>100) {
clearInterval(interval);
wait();
}
},smoothVal)
}
function wait(){
start = 0;
container.scrollTop = start;
setTimeout(function(){
smooth();
},waitVal)
}
smooth();
</script>
