Trigger that box whith a button?

Is it possible to trigger this rotate function with a click on a button? with :active it's possible to rotate it by clicking on the box. But you will need to keep the button pressed; is it possible to have some kind of toggle function on :active?
Is there any JavaScript to make a box flip?

One approach is as below, with comments in the code to explain what's going on:
// here we use document.querySelector() to retrieve the first <button> element
// in the document; we then use EventTarget.addEventListener() to bind the
// anonymous Arrow function as the event-handler for the 'click' event:
document.querySelector('button').addEventListener('click', (e)=>{
// the Event Object ('e') is passed to the function body, we retrieve
// the element to which the function was bound (Event.currentTarget)
// and from there we use Element.closest() to find the closest '.card-wrap'
// element:
e.currentTarget.closest('.card-wrap')
// from there we use Element.querySelector() to find the first (if any)
// flip-box element within that ancestor:
.querySelector('.flip-box')
// and use the Element.classList API to toggle the 'active' class
// on that 'flip-box' element:
.classList.toggle('active');

As long as you don't care about IE, classList is a well-supported option.
In your CSS file, change the following:
/* old: */
.flip-box:hover .flip-box-inner {
transform: rotateY(180deg);
}
/* new: */
.toggle .flip-box-inner {
transform: rotateY(180deg);
}
Then create a JavaScript file and add the following to it.
document
.getElementsByClassName('flip-box')[0]
.addEventListener('click', function () {
this.classList.toggle('toggle');
});
Then add the following <script> element to your html file.
<script src="<your JavaScript file name>.js"></script>
Here is the full code snippet:
document
.getElementsByClassName('flip-box')[0]
.addEventListener('click', function () {
this.classList.toggle('toggle');

Hope this helps.

define a generic .flip class that does a 180deg turn of any element it is assigned to with transform: rotateY(180deg).
add an original state transform: rotateY(0deg) to the class to be flipped (here .flip-box-inner showing the 'front').
Assign a Javascript click event listener to the parent to be clicked (here .flip-box).
have JS toggle the generic .flip class on/off.
UPDATE reply after OP comment
I replaced the snippet Javscript with jQuery syntax doing the same as the initial vanilla Javascript.
/*

*/
$('.flip-box').on('click', function() {
$('.flip-box-inner').toggleClass('flip');
});

How to get a click function to work for only the class of the object you clicked on

I have several buttons that use the same class. I am using a click function to make adjustments to the button. The issue I am having is the click function is controlling all of the buttons with the same class.
I am using $(document.body) as the selector because the data is derived asynchronously.
I'm wanting to toggle the class for both the triggerPosition and triggerButton. Originally, I just had $(document.body).on('click', '.triggerButton', function() { and thought adding 'triggerPosition' into it would allow the $(this) function to work for both the triggerPosition and triggerButton, but it doesn't.
Does anyone see what I need to do? The triggerButton is working for the specific one clicked on. Currently, the triggerPosition is the issue.
$(document.body).on('click', '.triggerButton', '.triggerPosition', function() {
$('.triggerPosition').toggleClass('active');
$(this).toggleClass('active');
});
.triggerRow {
display: block;
border-bottom: 1px solid #2f2f2f;
width: 500px;
}
.triggerButton {
width: 55px;
height: 30px;
background: #4d4d4d;
border: 1px solid #2f2f2f;
border-radius: 20px;
position: relative;

How to hide popup on click outside with animation

My point is:
If I click OPEN then should open the popup.
If click BACK then should close the popup
If I click outside popup then should close the popup.
Note: If I click anywhere inside popup when is open, then shouldn't close. Popup must closing only on outside click or BACK click.
How it currently work: If I click anywhere then popup is opening and closing.
So how to do this what I expect? I prepared JSFiddle and Code Snippet.

$(document).on('click touch', function(event) {
if (!$(event.target).parents().addBack().is('#open-1')) {
$("#card-1").toggleClass("flip");
}
});
You are toggle()ing the class here, instead use removeClass():
$(document).on('click touch', function(event) {
if (!$(event.target).parents().addBack().is('#open-1')) {
$("#card-1").removeClass("flip");
}
});
Then select the flipped div instead of the front one to stop toggling when the user clicks on the flipped div
$('.back.ease').on('click touch', function(event) {
event.stopPropagation();
});
Then add a class (for example close-1) to the back button:
Back
And then add a function to remove the flip class upon clicking it
$('.close-1').on('click touch', function() {
$("#card-1").removeClass("flip");
});

How to morph a plus sign to a minus sign using CSS transition?

I want to create a toggle button that morphs its shape from a plus sign to a minus sign.
Using CSS only, without the use of pseudo-elements.
My desired effect is to have the vertical line in the "+" sign to shrink into the horizontal line.
I know it's possible but I'm not sure which is the best route to take. I was thinking of doing something with the height but I'm worried about the line-height of browsers changing its position in the element.
$('button').on("click", function(){
$(this).toggleClass('active');
});
button {
color: #ecf0f1;
background: #e74c3c;
width: 50px;
height: 50px;
border: 0;
font-size: 1.5em;
}
button span {
transition: all .75s ease-in-out;
}
button.active span {
/* Code to morph + to - */
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<button><span>+</span></button>

Because of the simplicity of the shapes, the easiest way is just to make the + and - with elements. Using pseudo elements would be the cleanest solution, but you can also just use a DOM element and have a slightly messier document structure.
With that in mind, the actual solution is straightforward. We use CSS to position elements to resemble the desired characters, and then "morph" between them by animating that position.
Take a look over the following code, and try to understand what each rule is accomplishing.
button {
color: #ecf0f1;
background: #e74c3c;
width: 50px;
height: 50px;
border: 0;
font-size: 1.5em;
position: relative;
}
button span {
position: absolute;
transition: 300ms;
background: white;
border-radius: 2px;
}
/* Create the "+" shape by positioning the spans absolutely */
button span:first-child {
top: 25%;
bottom: 25%;
width: 10%;
left: 45%;
}
button span:last-child {
left: 25%;
right: 25%;
height: 10%;
top: 45%;
}
/* Morph the shape when the button is hovered over */
button:hover span {
transform: rotate(90deg);
}
button:hover span:last-child {
left: 50%;
right: 50%;
}
<button>
<span></span>
<span></span>
</button>

Using pseudo element ::before with content property
$('button').on("click", function() {
$(this).toggleClass('active');
});
button {

width: 50px;

button.active span::before {
content:"-"
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<button><span></span></button>
A (old) jquery Solution:
no need for span, you can do this using text() with a if statement in jquery
$('button').on("click", function() {
$(this).toggleClass('active');
$(this).text() == "+" ? $(this).text("-") : $(this).text("+");
});
button {
color: #ecf0f1;
background: #e74c3c;
width: 50px;
height: 50px;
border: 0;
font-size: 1.5em;
transition: all .75s ease-in-out;

<button>+</button>

Ah my bad I've overlooked that OP doesn't want to use any pseudo
elements. But the big advantage with pseudo elements would be that you have less HTML Code and a cleaner structure.
It's also a different morphing animation as OP wants but maybe someone else can use this.
So if you don't mind I'll let my suggestion there.
Maybe something like this?

<div class="button"></div>

TranslateX to appear as animating

I am trying to use more css and less Javascript for animation. I am running into an issue animating three different boxes. I have the boxes fade in with opacity by adding the fadeShow class to bring the opacity to 1. However, I am wanting the boxes to appear as if they are animating from the left side of the page to the right.
Here is a fiddle that shows it in action:
Click here to see
.info-box {
border: 1px solid black;
padding: 50px;
background: #00f;
color: #fff;
display: inline;
margin: 0 100px;
transition: 1s;
opacity: 0;
}
.info-box.fadeShow {
opacity: 1;
transform: translateX(150px);
}
I am trying to make the boxes animate over 150px OR if there is a better way to do this to put the boxes into their perminent state. What I mean by this is, if the boxes are supposed to be at left: 25%;, left: 45%; and left: 65%;, then I would want the boxes to be 150px to the left of that and then transition into place.

Firstly, to have the boxes slide over from the left, you should apply the negative transformation to the .info-box class:
transform:translatex(-150px);
And then reset it in the .fadeShow class:
transform:initial;
Secondly, you have the display property of the .info-box class set to inline, you'll need to change that as transformations can't be applied to inline elements.
Finally, for performance purposes, it's best to explicitly state which properties you want to apply transitions to:
transition:opacity 1s,transform 1s;
Or:
transition-duration:1s;
transition-property:opacity,transform;

Without CSS animations and calc function:
window.addEventListener("scroll", function(event) {
var top, green, red, yellow;
top = this.scrollY;
green = document.querySelector("#green"),
red = document.querySelector("#red"),
yellow= document.querySelector("#yellow");
if(top > 100){
green.classList.add("green", "active");
red.classList.add("red", "active");
yellow.classList.add("yellow", "active");
}
}, false);
*{box-sizing:border-box; height: 400vh}
body{margin: 0; padding-top: 200px}
.box{
width: 150px;
height: 150px;
opacity:0;
position: absolute;
transform: translateX(-150px);
opacity:0
}
#green{
background: green;
left: 25%;
}
#red{
background: red;
left: 45%;
}
#yellow{
background: yellow;
left: 65%;
}
#green.green{transition: all .3s ease}
#red.red{transition: all .6s ease}
#yellow.yellow{transition: all .9s ease}
#green.active,
#red.active,
#yellow.active{opacity: 1;transform: translateX(0);}

Now you can add EventTarget.addEventListener() and Element.classList
window.addEventListener("scroll", function(event) {
var top, green, red, yellow;
top = this.scrollY;
green = document.querySelector("#green"),
red = document.querySelector("#red"),
yellow= document.querySelector("#yellow");
if(top > 100){
green.classList.add("green", "active");
red.classList.add("red", "active");
yellow.classList.add("yellow", "active");
}
}, false);
*{box-sizing:border-box; height: 400vh}
body{margin: 0; padding-top: 200px}
.box{
width: 150px;
height: 150px;
opacity:0;
position: absolute
}
#green{
background: green;
left: 25%;
}
#red{
background: red;
left: 45%;
}
#yellow{
background: yellow;
left: 65%;
}
#green.green{animation:slideinGreen .3s ease}
#red.red{animation:slideinRed .6s ease}
#yellow.yellow{animation:slideinYellow .9s ease}
#green.active,#red.active,#yellow.active{opacity: 1}
#keyframes slideinGreen {
from {
left: calc(25% - 150px);opacity:0
}
}
#keyframes slideinRed{
from {
left: calc(45% - 150px);opacity:0
}
}
#keyframes slideinYellow {
from {
left: calc(65% - 150px);opacity:0
}
}

you need to set css transition to: transition: all 1s;
since you need to tell what properties you need to animate.
and using all means animate all css properties. also you need to set display: inline-block
.info-box {
border: 1px solid black;
padding: 50px;
background: #00f;
color: #fff;
display: inline-block;
margin: 0 100px;
transition:all 1s;
opacity: 0;
}

The transform isn't working because the child divs are set to display:inline.
Change that to inline-block.
