Switching items JS classes

I added the "setHeight" function to make the smooth opening/closing of items with dynamic content work.
The essence of the function, if the item with class "active" - then the height of the content is automatic from the height of the parent block (if you look at the function in the JS code, it will be clearer how it works).
If we click on the active item and it becomes inactive - everything works correctly.
The content height becomes 0 and the content is hidden.
Now the problem is that if we click not on active item but on another one and "active" class is removed from active item and another item is added - then content height is not removed from previous active item to "0".
How can I
const accordItems = document.querySelectorAll('.accordion__item');
accordItems.forEach(item => {
const accordText = item.querySelector('.accordion__text');
const content = item.querySelector('.accordion__content');
item.addEventListener('click', () => {
const activeItem = item.classList.contains('active');
accordItems.forEach(item => {
item.classList.remove('active');
setHeight()
});
if (!activeItem) {
content.style.height = 0;
}
if (!activeItem) {
item.classList.add('active');
setHeight()
}
});
function setHeight() {
if (content.offsetHeight) {
content.style.height = 0;
} else {
content.style.height = accordText.offsetHeight + 'px';
};
};
});

solve this problem?

I modified your Javsacript a bit to achieve it, your problem is your content always refers to the current item which is not the previous active item. We need pass item param to that function to refer to a correct item.
The key changes are under setHeight function
function setHeight(item, isActive) {
const content = item.querySelector('.accordion__content');
if (!isActive) {
content.style.height = 0;
} else {
content.style.height = accordText.offsetHeight + 'px';
};
};
const accordItems = document.querySelectorAll('.accordion__item');
accordItems.forEach(item => {
const accordText = item.querySelector('.accordion__text');
item.addEventListener('click', () => {
const activeItem = item.classList.contains('active');
accordItems.forEach(item => {
item.classList.remove('active');
setHeight(item, false)
});
if (!activeItem) {
item.classList.add('active');
setHeight(item, true)
}
});
function setHeight(item, isActive) {
const content = item.querySelector('.accordion__content');
if (!isActive) {
content.style.height = 0;
} else {
content.style.height = accordText.offsetHeight + 'px';
};
};
});

How can I arrange my divs in 2 columns so it looks like a grid/photo gallery?

I am new to coding and web design. Right now, I am constructing a portfolio website which showcases the other websites I've created. I am trying to create a layout where my Divs on the site are in two columns (under 'my work'). I am trying to figure out what to use but I'm unsure if I'm being honest. I've played around with display flex and display grid but I did not get the result I wanted. Here is my below... I will also link another persons' site to give you a visual of what I'm trying to achieve. Any help or tips would be greatly appreciated... Thank you!
Also, I will include my code.

use display : flex :
warp the four divs in a big div with class flex-main.
and this is the css:(only the parts with changes)
.main-body {
background-color: rgb(244,132,95);
width: 100%;
}
.flex-main{
display: flex;
flex-wrap: wrap;
flex-direction: row-reverse;
justify-content: center;
}
.main-body2 {
padding-top: 150px;
padding-bottom: 150px;
float: left;
width: 35%;
margin-right: auto;
margin-left: auto;
}
that would work as you want.good luck!

Divs not in the right position when clicking button

I got 6 divs of which they each have an image and a button (javascript). When I click on a button of one of the divs, another div will show on the exact same place of the button of the div you clicked. When I click on all buttons separate, there is no problem. But when I click by example 'auto 2' and 'auto 3', 'auto 3" will show on the right side of the screen, not on the place where it will show when you click on the button separate. I got also this problem with 'auto 4,5 and 6. I dont got this problem with the first div 'auto 1' because its has an absolute position. When I used an absolute position on the other divs i couldnt position them properly. I think the problem has to do something with the fact that a div has a block display and that by example 'auto 2' pushes 'auto 3" to the side because it is wider than it looks.
PS. srry for my bad english and I used and internal javascript with tags because an external document like .js doesnt work for me for some reason
Thanks in advance!

Using a toggle to turn off all other active classes on separate divs

I'm having a small issue getting a toggle to work in a particle way, for all I know it can't be done using a toggle which is why I'm writing on here to see if someone can show me the best method. So at the moment I have 3 divs all of which have onclick events, and each have a toggle css class. What I'm trying to achieve is when one is clicked if the others are active they return back to the previous class.
function orgClick(clicked_id) {
var id = (clicked_id);
document.getElementById(id).classList.toggle('org_container_active');
}
.org_container {
width: 20%;
margin-left: 6.25%;
margin-right: 6.25%;
margin-top: 15px;
border: 2px solid #e1dfe1;
border-radius: 15px;
display: inline-block;
}
.org_container_active {
width: 20%;
margin-left: 6.25%;
margin-right: 6.25%;
margin-top: 15px;
border: 2px solid #2bbe43;
border-radius: 15px;
display: inline-block;
}
.org_name {
background-color: #f5f0f5;
border-bottom: 2px solid #e1dfe1;
border-top-left-radius: 15px;
border-top-right-radius: 15px;
text-align: center;
font-weight: bold;
padding-top: 5px;
padding-bottom: 5px;
}
.org_logo {
padding-top: 10px;
margin: auto;
width: 100px;
}
.org_info {
padding: 5px 10px 10px 5px;
}
<div class="org_container" id="org1" onclick="orgClick(this.id);">
<div class="org_name">
<p align="center">Org 1</p>
</div>
<div class="org_logo">
<img src="http://server3.sulmaxcp.com/logo_unavailable.svg" width="100px" height="100px" ondragstart="return false;">
</div>
<div class="org_info">
<p></p>
</div>
</div>
<div class="org_container" id="org2" onclick="orgClick(this.id);">
<div class="org_name">
<p align="center">Org 2</p>
</div>
<div class="org_logo">
<img src="http://server3.sulmaxcp.com/logo_unavailable.svg" width="100px" height="100px" ondragstart="return false;">
</div>
<div class="org_info">
<p></p>
</div>
</div>
<div class="org_container" id="org3" onclick="orgClick(this.id);">
<div class="org_name">
<p align="center">Org 3</p>
</div>
<div class="org_logo">
<img src="http://server3.sulmaxcp.com/logo_unavailable.svg" width="100px" height="100px" class="noselect">
</div>
<div class="org_info">
<p></p>
</div>
</div>

document.querySelectorAll() lets you search for all elements that match a CSS selector. You can use it to deactivate all active containers:
for (let div of document.querySelectorAll('.org_container_active')) {
div.classList.remove('org_container_active');
}

White space and background moves

There is a faq on my website for a school project created with Javascript animations.
The problem is:
1; The background moves when 2 or more faqs are opened.
2; There is a white space beneath the background.
The faq on my website (click for the image)
The javascript
var main = function() {
$('.article').click(function() {
$('.article').removeClass('current');
$('.description').hide();
$(this).addClass('current');
$(this).children('.description').show();
});
$(document).keypress(function(event) {
if(event.which === 111) {
$('.current').children('.description').toggle();
}
else if(event.which === 110) {
var currentArticle = $('.current');
var nextArticle = currentArticle.next();
currentArticle.removeClass('current');
nextArticle.addClass('current');
}
});
};
$(document).ready(main);

I jsfiddle your question http://jsfiddle.net/wz7eojqp/
I couldn't find the problems you described.
but I think that regarding the white space in the bottom of your page the problem is default browser margin. try to body{margin: 0;} or even better reset code.
http://meyerweb.com/eric/tools/css/reset/

Please close all (!) your html tags. It will fix many problems.
I've created a jsfiddle: http://jsfiddle.net/7ypk522y/
I have deleted your css class .jumbotron because you don't use it and changed it with the following lines. I hope this fixes your problem.
body {
background: url("http://i.imgur.com/JvdPG8h.png") no-repeat center center fixed;
-webkit-background-size: cover;
-moz-background-size: cover;
-o-background-size: cover;
background-size: cover;
background-repeat: no-repeat;
padding: 20px;
}
