classList.toggle for several elements Javascript

I designed a vertical slide from bottom navigation on mobile. I would like each tab could move (up or down) with the upper one. May be the toggle method isn't the right one. I use vanilla JS.
Here is my function. The two last lines are to show the idea. I would like to write it in a better way.
let children = document.getElementById('mobile-container').children;
for (let i = 0; i < children.length; i++) {
children[i].addEventListener("touchstart", function () {
children[i].classList.toggle("unfold");
children[i-1].classList.toggle("unfold");
children[i-2].classList.toggle("unfold");
});
}
Here is my HTML
<div id="mobile-container">
<div id="mobile-projets" class="mobile">
<h2>Projets</h2>
</div>
<div id="mobile-expertises" class="mobile">
<h2>Expertises</h2>
</div>
<div id="mobile-clients" class="mobile">
<h2>Clients</h2>
</div>
</div>
Here is my CSS
#mobile-container {
display: block;
position: relative;
width: 100%;
height: 85vh;
top: 15vh;
}
#mobile-projets {
width:100%;

Recreate Adobe Portfolio Dual Hover Effect On Image & Text Block

ive been trying to recreate the hover dual effect that is on https://andreas-demo.myportfolio.com/
However i cant seem to get both to align correctly and then i cannot get the affect that hovers over the entire section but that changes BOTH: 1- Darkening the image, 2 -inversing the colors.
I want to be able to get both affects to happen while hovering over the entire block, just like on the site above^.
Here's my code;
img {
display: block;
width: 60%;
height: 450px;
background-color: #f2f2f2;
!important;
-webkit-filter: brightness(100%);
}
a img:hover {
-webkit-filter: brightness(60%);
-webkit-transition: all 1s ease;
-moz-transition: all 1s ease;
-o-transition: all 1s ease;
-ms-transition: all 1s ease;
transition: all 1s ease;
}
.media {
background-color: #f2f2f2;
!important;
text-align: center;
}
p {
display: inline-block;
vertical-align: middle;
}
<div class="container">
<a href="">
<div class="media">
<img src="img/pexels-photo-733438.jpeg" class="img-fluid" alt="Responsive image">
<p>PROJECT 1</p>
<p>2017</p>
</div>
</a>
</div>

On container:hover, set your container'background-color as black (default to white) and set the image opacity as 0.5.

Move the :hover pseudo-class to one of the 3 parent (wrapper) elements -
.container, .container > a, or .media element. This will have the effect of adding the overlay to both elements on :hover.
Like this:
.container {
font-family: Arial;
}
.container:hover {
-webkit-transition: all 1s ease;
-moz-transition: all 1s ease;
-o-transition: all 1s ease;
-ms-transition: all 1s ease;
transition: all 1s ease;
}
.container__link {
display: flex;
text-decoration: none;
}
.media {
flex: 6;
background-color: #222222;
}
img {
display: block;
width: 100%;
height: 450px;
opacity: 1;
-webkit-transition: all 1s ease;
-moz-transition: all 1s ease;
-o-transition: all 1s ease;
-ms-transition: all 1s ease;
transition: all 1s ease;
}
.container:hover .media img {
opacity: 0.3;
}
.description {
flex: 4;
display: flex;
align-items: center;
justify-content: center;
flex-direction: column;
-moz-transition: all 1s ease;
-o-transition: all 1s ease;
-ms-transition: all 1s ease;
transition: all 1s ease;
background-color: #ffffff;
color: #222222;
}
.container:hover .description {
background-color: #222222;
color: #ffffff;
}
p {
padding: 0;
margin: 0;
}
<div class="container">
<a href="" class="container__link">
<div class="media">
<img src="http://via.placeholder.com/350x150" class="img-fluid" alt="Responsive image">
</div>
<div class="description">
<p>PROJECT 1</p>
<p>2017</p>
</div>
</a>
</div>

Show div when hover over another separate div

I have searched the web and found similar questions to my own, but I have not been able to achieve the results that I am looking for. I am not the most well versed with html/css/and javascript/jquery so I am wondering if it is an error on my part with how I am formatting everything, or the path to which I am trying to write these results.
I have three circles, spaced equally in the center of the page. Each circle links out to a different page. On hovering over a circle, a span is revealed (by changing the opacity property in css) that provides a title for where that link goes.
What I am having trouble doing is: When you hover over each circle, in addition to a span being revealed that provides a title, I want to have a short descriptive text appear below the circles. When you mouse out of that said circle, the descriptive text will disappear. Each circle must have its own descriptor text.
From what I have gathered, the jquery hover on event is likely the best way to do this, however I cannot seem to get the syntax correct to make it work.
<script>
jQuery(document).ready(function() {
jQuery('#text1').hide();
});
jQuery(document).ready(function() {
jQuery('.grid_1').hover(function() {
jQuery(this).find('#text1').show();
},
function() {
jQuery('#text1').hide();
});
});
</script>
Any and all help would be greatly appreciated. Please let me know if I should clarify anything.
Link to jsfiddle

Your jquery references #text1 and it should be .text1 since that element is a class. Also $(this).find('.text').show(); won't work because .text is not a child of the thing you're hovering over ($(this)). Just use $('.text1')
$(document).ready(function() {
$('.text1').hide();
});
$(document).ready(function() {
$('.grid_1').hover(function() {
$('.text1').show();
},
function() {
$('.text1').hide();
});
});

Though I would re-write it to be a little more flexible and with less code like this, utilizing a data attribute in the .grid circles to define the text block class to show, then adding/removing a class that shows the text instead of using jquery's $.hide() and $.show()
$(document).ready(function() {
$('.grid').hover(function() {
$($(this).attr('data-text')).addClass('show');
},
function() {
$($(this).attr('data-text')).removeClass('show');
});
});

I'll provide a css solution since there exist a jquery answer
Add the following to your css
.fmcircle_out:hover .description{
opacity:1;
}
.description{
opacity:0;
transition:opacity 1s;
}
.fmcircle_out a{
text-decoration:none;
}
.fmcircle_out:focus {
opacity: 1;
}

Jquery code Which hide another div on hover and make it visible when mouse move out.
<script>
$(document).ready(function(){
$('.grid_1').hover(
function () {
$('#text1').hide();
},
function () {
$('#text1').show();
}
);
});

Example ins jsfiddle : https://jsfiddle.net/9objpv9x/
Try to hover to see animation and modal links and then click the "Link1" and close modal to see what happens next.
I just don't know where to start digging.

Actually the "link1" is left at "focus" state and the outline is displayed due to default bootstrap css property:
a:focus {
outline: 5px auto -webkit-focus-ring-color;
outline-offset: -2px;
}
To override it, Modify it in your css.
a#id:focus {
outline: 0px;
}
To remove the focus state after the modal close,
We need to trigger modal in jquery instead of having "data-target" in HTML.

Sidebar toggled content squeezed

below is my code:
html:
<div id="wrapper" style="background-color:red">
<div id="sidebar-wrapper" style="background-color:yellow">sidebar
<div id="result"></div>
</div>
<div id="header" class="container-fluid">
<div class="navbar">
<a href="#menu-toggle" id="menu-toggle" >Press</a>
<div>This is a serious health setback for me personally, but one of CN's core strengths is that we have a very experienced and tightly-knit senior <span id="counterId"></span></div>
</div>
</div>
css:
#wrapper {
width: 100vw;
padding-left: 0;
-webkit-transition: all 0.5s ease;
-moz-transition: all 0.5s ease;
-o-transition: all 0.5s ease;
transition: all 0.5s ease;
}
#wrapper.toggled {
padding-left: 250px;
}
#sidebar-wrapper {
z-index: 1000;
position: fixed;
left: 250px;
width: 0;
height: 100%;
margin-left: -250px;
overflow-y:auto;
background: #5F657C;
-webkit-transition: all 0.5s ease;
-moz-transition: all 0.5s ease;
-o-transition: all 0.5s ease;
transition: all 0.5s ease;
box-shadow: inset -10px 0px 10px -7px grey;
}
#wrapper.toggled #sidebar-wrapper {
width: 250px;
}
js:
$("#menu-toggle").click(function(e) {
e.preventDefault();
$("#wrapper").toggleClass("toggled");
});
The jsfiddle is below:
JSFIDDLE
My problem is for the left side yellow div, the content inside will kinda squeeze together when the sidebar slide to the left.
I want to make it just hide underneath and don't want the content to be squeezed. Do you guys have any idea?

You could do it like this:
$("#menu-toggle").click(function(e) {
e.preventDefault();
$("#wrapper").toggleClass("toggled");
});
#wrapper {
padding-left: 0;
-webkit-transition: all 0.5s ease;
-moz-transition: all 0.5s ease;
-o-transition: all 0.5s ease;
transition: all 0.5s ease;
}
#wrapper.toggled {
padding-left: 250px;
}
#sidebar-wrapper {
z-index: 1000;
position: fixed;
left: -250px;
width: 250px;
height: 100%;
overflow-y: auto;
background: #050545;
-webkit-transition: all 0.5s ease;
-moz-transition: all 0.5s ease;
-o-transition: all 0.5s ease;
transition: all 0.5s ease;
box-shadow: inset -10px 0px 10px -7px grey;
}
#wrapper.toggled #sidebar-wrapper {
left: 0;
}

<div id="wrapper" style="background-color:red">

The width is set default to 250px. In my snippet I'm playing with the offset left to hide/show the sidebar. Study my code and you'll see how it works.
