Element goes above other element - CSS

I have a hamburger menu inside my website and if I go inside a specific which I have a card with some other elements inside. But if I open the menu while I'm inside the page with this card element the card goes above the menu for some reason. I tried almost everything but I can't get it right. I can't see where is my mistake with the CSS code...
My react component (html):
import TopNavBarMobileComponent from "../TopNavMobileComponent";
import github_icon from '../../assets/github_icon.png'
import instagram_icon from '../../assets/instagram_icon.png'
import my_picture from '../../assets/my_picture.jpg'
import '../../css-mobile/AboutMeStyle.css'
function AboutMeMobile() {
return (

CSS has a 3d object location - the obvious x and y, but there is also a z element. This Z element determines which elements display over others, and which go behind. To set the z element (or index), use the z-index property.

Automate using JavaScript:
Animate the slider for n-th child elements using JS.
var elements = document.querySelectorAll('li');
var totalElements = elements.length;
var slider = document.querySelector('.slider');
elements.forEach((el, i) => {
el.addEventListener('mouseenter', () => {
slider.style.width = `${(100 / totalElements) * (i + 1)}%`;
});
el.addEventListener('mouseleave', () => {
slider.style.width = '0%';
});
});

You can use margin for position and include hover code to see the change
.container .slider{
position:relative;
height: 8px;
width: 20%;
background: #007eff;
margin:45px;
}
.container .slider:hover{
opacity:0.2;
}

How do I get my site to scroll properly on mobile

I am building a site with a js menu that loads content into a container div. The site works fine on desktop, and on the respsonsive mobile emulator on my desktop browser, but on my phone it doesn't scroll.

<div id="bg"></div>
</body>
I think it has something to do with the height of the #page-content div that I have set to min-height: calc(100vh - 138px) to compensate for the navbar at the top and the footer at the bottom.
Alternatively it may have something to do with visibility or positioning on the other elements. The layout of the site changes completely on smaller devices...
I've tried adding -webkit-overflow-scrolling: touch; to various elements, but even when I set it to all elements using * {} it still doesn't scroll.
I've read a dozen posts some of which point to position: fixed so i've tried switching to absolute positioning...
It seems like the whole page tries to scroll instead of the #content or #page-content div... i'm just at a loss! PLEASE HELP!!!

Add below CSS inside #media only screen and (max-width: 800px) in your style.css at line no 4030. It'll unable your parent scroll and disable your individual container scroll and also you add an individual footer in each container. So I also hide all container's footer and visible only last container footer. Try this I hope it'll help you out. Thanks

HTML/CSS: Add Icon to Text Button

I'm relying on increasing the top and bottom paddings of the center element to create a hover effect, seen below.
Keeping this effect, is there a way to do the following:
To make room for their respective icons, lower the text (help and logout) a little bit (I know I can do position: relative, and then top: 7px, for example, but that messes up the hover animation effect because the center of the 'white' expansion should be the center of the green header)
Now that the text is lowered, I want to add a transparent background sprite to each of the two 'buttons' - a question mark symbol for "help", and another symbol for "logout". So the background would still be green, and on top of the green background, I will see a symbol for each button, and the text below each symbol. If I simply do
.help {background: url() no-repeat -2px 0;}, for example, the image moves along with the hover effect because the height of the element is increased.
The sprites I'm going to using for the background/icons are in the form of:
{url(../theme/images/top_sprites.png) no-repeat -2px 0;}
So how can I use the sprites as Icons for these 'buttons' while keeping the text, the green background, as well as the animation? Note that the borders are added to make it clearer how the animation/effect works.
.header {
height: 50px;
background-color: #008b10;
}
.menu {
padding: 16px;
text-align:center;
font-family: Raleway, arial, sans-serif;
float:left;
overflow: visible;
border: 1px solid blue;
}
.menu a:hover {
background-color: #ffffff;
color: #008b10;
padding: 16px 5px;
}
.menu a {
/*box-sizing: border-box;*/
/*float:left*/
text-decoration: none;
transition: 0.4s;
color: #ffffff;
font-size: 13px;
text-decoration: none;
padding: 0 5px;
border: 1px solid red;

<div class="menu">
<a class="help" href="#" id="online_help">Help</a>
<a class="logout" href="#" onclick="openLogout();">Logout</a>

You could animate a pseudoelement on the anchor.

.header {
min-height: 50px;
background-color: #008b10;
}
.menu {
padding: 0 16px;
font-family: Raleway, arial, sans-serif;
border: 1px solid blue;
}
.menu a {
text-decoration: none;
transition: 0.4s;
color: #ffffff;
font-size: 13px;
padding: 16px 5px;
display: inline-flex;
align-items: center;
flex-direction: column;
position: relative;
}
.menu a span {
position: relative;
}
.menu a:before {
transition: 0.4s;
content: '';
display: block;
position: absolute;
background: white;
opacity: 0;
transform: scaleY(.5);
left: 0;
right: 0;
top: 0;
bottom: 0;
}
.menu a:hover:before {
transform: scaleY(1);
opacity: 1;
}
.menu a img {
max-width: 15px;
display: block;
position: relative;
padding-bottom: 4px;
}
.menu a:hover {

Unless you have a very good reason for doing so, don't use and . Seems unnecessary and convoluted.
It's quite simple to grab the value from an <input> or <textarea> with JavaScript and place it in another element, like a <div>. Here's an uber basic example that would produce a live example (pretend that the green DIV is a photo of a t-shirt).
var $text = $( '.tshirt-text' );
var $demoText = $( '.demo-tshirt-text' );
$text.on( 'keyup', function ( e ) {
$demoText.text( $text.val() );
} );
.demo-tshirt {
position: relative;
width: 300px;
height: 400px;
background-color: seagreen;
}
.demo-tshirt-text {
position: absolute;
top: 30%;
left: 50%;
width: 50%;
transform: translateX( -50%);
color: white;
font-family: Arial, sans-serif;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<label for="tshirt-text">
Text: <input type="text" id="tshirt-text" class="tshirt-text" name="tshirt-text">
</label>
<div class="demo-tshirt">
<div class="demo-tshirt-text"></div>
</div>

If the entire content of your iframe is just the background definition, you could write the HTML to the iframe document directly.
from Write elements into a child iframe using Javascript or jQuery ...
var ifrm = document.getElementById('myIframe');
ifrm = ifrm.contentWindow
|| ifrm.contentDocument.document
|| ifrm.contentDocument;
ifrm.document.open();
ifrm.document.write('Hello World!');
ifrm.document.close();
