How can I create dynamic input sliders with react?

I am trying to create a modal component for my application and my modal needs a slider to dynamically scale the image in the modal based on the user's input. I am done creating this modal and it looks like this:
The problem I have is when I click on the slider especially on the value in the middle, the slider jumps to the third value. It only comes to the second value after going to the third value.
This is my JSX code
class pizzaModal extends Component {
state = {
toggle: false
}
toggleHandler = ()=>{
this.setState({
toggle: !this.state.toggle
});
}
render (){
return (
<div className={styles.Pizzamodal}>
<div className={styles.ModalContainer}>
<div className={styles.ImageContainer}>
<img src={pizzapicture} alt="pizzapicture"/>
</div>
<div className={styles.DetailsContainer}>
<div>
<div className={styles.TextDetails}>
<h1>Chicken Curry</h1>
<p>Red onions, bell peppers, <br/> chicken, pineapple, mozarella, <br/> tomatosauce, curry, chilli peppers.</p>
</div>
<div>
<form className={styles.switchButton}>
<input type="radio" name="pizza" id="small" value="small" onChange={this.toggleHandler}
checked={!this.state.toggle}/>
<label for="small">25cm</label>
<input type="radio" name="pizza" id="medium" value="medium" onChange={this.toggleHandler}
checked={this.state.toggle}/>
<label for="medium">30cm</label>
<input type="radio" name="pizza" id="large" value="large" onChange={this.toggleHandler}
checked={this.state.toggle}/>
<label for="large">35cm</label>
</form>
</div>
</div>
</div>
</div>
</div>
)
}
}
export default pizzaModal;
This is the CSS
*{
margin: 0;
padding: 0;
box-sizing: border-box;
}
.Pizzamodal{
position: fixed;
z-index: 300;
top: 25px;
left: 250px;
width: 880px;
height: 610px;
background-color: white;
border-radius: 20px;
}
.ModalContainer{
display: flex;
justify-content: space-between;
}
.ImageContainer img{
margin-top: 150px;
margin-left: 90px;
}
.DetailsContainer{
margin-right: 20px;
margin-top: 40px;
}
.TextDetails h1{
font-size: 1.2rem;
font-family: 'Roboto', sans-serif;
padding-bottom: 40px;
}
.TextDetails p{
font-size: 1.1rem;
font-family: 'Roboto', sans-serif;
padding-bottom: 40px;
}
.switchButton input{
position: absolute;
clip: rect(0, 0, 0, 0);
height: 1px;
width: 1px;
border: 0;
overflow: hidden;
}
.switchButton label{
display: inline-block;
width: 100px;
background-color: #e4e4e4;
color: rgba(0, 0, 0, 0.6);
font-size: 14px;
font-weight: normal;
text-align: center;
text-shadow: none;
padding: 6px 14px;
border: 1px solid rgba(0, 0, 0, 0.2);
box-shadow: inset 0 1px 3px rgba(0, 0, 0, 0.3), 0 1px rgba(255, 255, 255, 0.1);
transition: all 0.1s ease-in-out;
}
.switchButton input:checked + label{
background-color: #F07718;
color: #fff;
box-shadow: none;
}
.switch-field label:first-of-type {
border-radius: 4px 0 0 4px;
}
.switch-field label:last-of-type {
border-radius: 0 4px 4px 0;
}

You're using a boolean toggle state (either true or false) to represent a three-way choice.
Instead use:
state = {
selected: "small"
}
toggleHandler = (size)=> () =>{
this.setState({
toggle: size
});
}
and in the inputs:
onChange={this.toggleHandler("small")} checked={this.state.toggle==="small"}
onChange={this.toggleHandler("medium")} checked={this.state.toggle==="medium"}
onChange={this.toggleHandler("large")} checked={this.state.toggle==="large"}

VueJS template - Flip between Login Form & Register Form

I am trying to Flip between 'Login Form' & 'Register Form'. I tried to use code which I came across on codepen Flat HTML5/CSS3 Login Form. The code works just fine, but when I integrate the HTML code within a Vue Template the Form does not flip to the 'Create an account' form. I have observed that there is something to correct in the JavaScript but I am not able to understand exactly what.
My code is as below:
HTML
<template id="login-page"> // PROBLEM When this Tag is added and called using VueJS component
<div class="login-page">
<div class="form">
<form class="register-form">
<input type="text" placeholder="name"/>
<input type="password" placeholder="password"/>
<input type="text" placeholder="email address"/>
<button>create</button>
<p class="message">Already registered? Sign In</p>
</form>
<form class="login-form">
<input type="text" placeholder="username"/>
<input type="password" placeholder="password"/>
<button>login</button>
<p class="message">Not registered? Create an account</p>
</form>
</div>
</div>
</template> // PROBLEM When this Tag is added and called using VueJS component
VueJS
// Vue component: login-page
const LoginPage = {
template: '#login-page',
data() {
return {
login_message: 'Please enter your credentials to login.',
loginStage: 'login-form',
}
},
}

$('.message a').click(function(){
$('form').animate({height: "toggle", opacity: "toggle"}, "slow");

While #Fred has accepted #chr's answer, this is (still) a mis-use of Vue.
(Note this not an attempt to reproduce the working fiddle, but to answer the general question of how to Flip between 'Login Form' & 'Register Form' using a more Vue-oriented approach)
In the Vue way of doing things the switch between the login form and the register form should be done with markup, using Vue conditional rendering rather than calling functions showRegisterForm() and showLoginForm().
toggleForm doesn't require a parameter because the model knows what the value of currentForm is already.
An if and else is the simplest approach, making use of a property in your Vue model, such as currentForm: 'login' that chr introduced in their answer.
The HTML needs only slight changes
<div id="login-page" class="login-page">
<div class="form">
<form v-if="currentForm.toLowerCase() === 'register'" class="register-form">
<input type="text" placeholder="name"/>
<input type="password" placeholder="password"/>
<input type="text" placeholder="email address"/>
<button>create</button>
<p class="message">Already registered?
Sign In</p>
</form>
<form v-else class="login-form">
<input type="text" placeholder="username"/>
<input type="password" placeholder="password"/>
<button>login</button>
<p class="message">Not registered?
Create an account</p>
</form>
</div>
</div>
A partial look at the model needed for this could be
const model = new Vue({
data : {
'currentForm' : 'login',
...
},
...
methods : {
toggleForm() {
this.currentForm = this.currentForm === 'login' ? 'register' : 'login';
}
},
...
});
When the value of currentForm changes Vue will take care of changing which of the forms will display.
Also see the answer to the question VueJS - Swap component on click for a more generalized approach.

You are mixing up the use of Vue as library and Vue as framework. It looks like, you are actually trying to use Vue as library, so I changed the code accordingly, here is myfiddle. You can just need to add a transition, for more information look into the documentation Enter/Leave & List Transitions.
HTML:
<div id="login-page" class="login-page">
<div class="form">
<form class="register-form" v-show="showRegisterForm">
<input type="text" placeholder="name"/>
<input type="password" placeholder="password"/>
<input type="text" placeholder="email address"/>
<button>create</button>
<p class="message">Already registered? Sign In</p>
</form>
<form class="login-form" v-show="showLoginForm">
<input type="text" placeholder="username"/>
<input type="password" placeholder="password"/>
<button>login</button>
<p class="message">Not registered? Create an account</p>
</form>
</div>
</div>
JS:
new Vue({
el: '#login-page',
data() {
return {
login_message: 'Please enter your credentials to login.',
loginStage: 'login-form',
currentForm: 'login',
}
},
computed: {
showRegisterForm() {
return this.currentForm === 'register';
},
showLoginForm() {
return this.currentForm === 'login';
},
},
methods: {
toggleForm(formName) {
this.currentForm = formName;
},
},
});

#chr solutions works for me except the the first two lines of the JavaScript code that had to be changed since in my case I have an existing Vue which calls the Login Component which then activates the Login Template.
JavaScript
// Vue component: login-page
const LoginPage = {
template: '#login-page',
data() {
return {
login_message: 'Please enter your credentials to login.',
currentForm: 'login',
}
},
computed: {
showRegisterForm() {
return this.currentForm === 'register';
},
showLoginForm() {
return this.currentForm === 'login';
},
},
methods: {
toggleForm(formName) {
this.currentForm = formName;
},
},
}

Stephen P's code works as well and is much neater, except that the first form should have the register in single quotes i.e. 'register', which is corrected below.
HTML
<div id="login-page" class="login-page">
<span><h1>{{currentForm.toUpperCase()}} FORM</h1></span>
<span><h5>Please enter your credentials to {{currentForm.toLowerCase()}}.</h5></span>
<div class="form">
<form v-if="currentForm.toLowerCase() === 'register'" class="register-form">
<input type="text" placeholder="name"/>
<input type="password" placeholder="password"/>
<input type="text" placeholder="email address"/>
<button>create</button>
<p class="message">Already registered? Sign In</p>
</form>
<form v-else class="login-form">
<input type="text" placeholder="username"/>
<input type="password" placeholder="password"/>
<button>login</button>
<p class="message">Not registered? Create an account</p>
</form>
</div>
</div>
JavaScript
// Vue component: login-page
const LoginPage = {
template: '#login-page',
data() {
return {
currentForm: 'login',
}
},

toggleForm()
{
this.currentForm = this.currentForm === 'login' ? 'register' : 'login';

Display none and block does not work via JavaScript

I am developing a single-page-website because it's cheaper at firebase to host. My problem is that I must manage different screens at the single HTML file. So I must make screens disappear and appear again. I want to do this with main_dashboard_page.style.display = 'none'; and main_dashboard_page.style.display = 'block';.
Here is my HTML code:
<!-- _______________________________________________________________________________________________________________________________________ -->
<!-- L O G I N P A G E -->
<!-- _______________________________________________________________________________________________________________________________________ -->
<div class="login_page" id="login_page">
<div class="card_view">

<div class="login_form validate-form">
<span class="login_form_title p-b-26">

</span>
<div>
<label for="email_field">E-Mail</label>
<input type="text" id="email_field" name="email_field" placeholder="E-Mail">
<label for="password_field">Passwort</label>
<input type="password" id="password_field" name="password_field" placeholder="Passwort">
<input type="submit" value="Einloggen" onclick="login()">
</div>
<div class="center_text_container p-t-115">
<span class="txt1">

</span>
<a class="txt2" onclick="goToSignUp()">

</a>
</div>
<div class="modal">
<div class="modal-content">

</div>

As you can see I have two screens, which are represented as the divs:
1) ID: login_page
2) ID: html_side_main
Now the login_page should disapear and the html_side_main should appear, when user is logged in. I chek it with firebase as you could see in js:
firebase.auth().onAuthStateChanged(function(user) {
if (user) {
changePage();
}
else {
var main_dashboard_page = document.getElementById("html_side_main");
main_dashboard_page.style.display = 'none';
}
});
function changePage() {
if (document.readyState === "complete") {
var login_page = document.getElementById("login_page");
var register_page = document.getElementById("register_page");
var main_dashboard_page = document.getElementById("html_side_main");
login_page.style.display = 'none';
main_dashboard_page.style.display = 'block';
}
As I heared that the css has a higher priority in the display of elements I would post the CSS here too:

PROBLEM:
To set the display option in js does not work. First both of the divs are shown and when user logged in both of them disapear. I don't know why, but please can you help me to fix this this problem? Because the website is basicly finished, and I only have to convert it to a one html file.
Thanks in advance.

In isolation of a codepen, this works:
function setStyle(propValue){
console.log(propValue)
var main_dashboard_page = document.getElementById("html_side_main");
main_dashboard_page.style.display = propValue
}
Thus it is not a js⇄css problem. (as your title suggests)
Look deeper into your firebase events, add some console.log() into the code to verify, things actually get called, when you expect them to.
Generally, try to isolate your problem further and further (remove all unrelated clutter, i.e. your inner and unrelated html) as long as the problem persists...
As I heared that the css has a higher priority in the display of elements
Not true. Precedence is from lowest to highest:
Browser default
External style sheet (like yours)
Internal style sheet (commonly in <head>)
Inline style
...javascript runtime changes of CSS properties are a 4., they change the inline styles (at runtime, after DOM construction, so they are also higher than pre-exisiting inline styles), as you can also inspect with your browser's dev tools.
Your problem is much more trivial. Your #login_page is a parent of your #html_side_main, thus hiding it hides all. You are one closing </div> short. If your intend is to have two neighbouring (not nested) elements, probably meant to be somewhere around line :63.
(This is, why isolation aka damping down is good :-)

I would recommend to not use .style on a DOM node. Instead, I would recommend to create a class in css like:
.display-none {
display: none;
}
and then add the class via javascript:
login_page.className += " display-none";
That way you will have all your styles in your css and not in your javascript

PHP code:
<?php
$connection =mysqli_connect('localhost','root','','textstorage');
if (mysqli_connect_errno()) {
echo "Failed to connect to MySQL: " . mysqli_connect_error();
}
if($_POST['tshirt-text']){
$tshirt-text =$_POST['tshirt-text'];
$size =$_POST['size'];
$q = "insert into information values('','tshirt-text','size')";
$query = mysqli_query($connection,$q);
if ($query) {
echo"data inserted";
}
}
?>

If you check the console, you'll see that the problem is the first line inside of the javascript click function...
var tshirt-text = $('#tshirt-text').val();
... because '-' is not a valid character for javascript variable names. Just change it by tshirttext (in all your code), and you will see the alert and should be able to go on.
I hope it helps

You've got some errors with you JavaScript. Try running your JavaScript through a validator (for example, http://beautifytools.com/javascript-validator.php) to see where your errors are. In addition to the one A. Iglesias found, you've got an extra clothes parenthesis on line 1, the same tshirt-text error from line 3 is repeated on line 9, and your syntax for an event handler for success on line 13 isn't right, but I can't tell what you're trying to do.
You've also got a conceptual problem. Lines 17 through 22 should be inside your $(document).ready handler. The ready event runs after the initial HTML is loaded into the browser and ready to go, so any reference to HTML elements outside of that event handler may be referring to them before they're ready.
I wanted to make this a comment to your question, but it's too long, so hopefully it's okay an answer. Perhaps once you've fixed some of these JavaScript issues, post an update to your question in the form of an edit and we can then see what else is going on if it's not working.
edit: I reformatted your JavaScript and tried to resolve any syntax errors. If you open up your browser developer tools and run this JS Fiddle (with comments and without comments), you'll see there are no syntax errors in the console. That doesn't mean it works, just that it's syntactically valid. In fact, this shouldn't work, because the AJAX success handler I wrote simply logs the response.
$(document).ready ( // When function parameters and code blocks are big, I like to
// put the opening ( or { at the end of line and put the the
// closing } or ) in the same column way at the end. I find it
// is easier to keep track of openings and closings.
function() { // no extra close parenthesis right after "function"
$("#btn").click(
function()
{
var tshirtText = $('#tshirt-text').val(); // Variable names can only be
// letters, numbers, dollar symbols,
// and underscores. They cannot start
// with numbers.
var size = $('#size').val();
alert("tshirt-text");
$.ajax(
{ // For clarity, I'll separate out the opening ( and opening {
// and the closing } and closing ) when they are one after the other.
type: 'POST'
// I like to put my commas on the next line rather than the previous line.
// I think it makes it more clear that you're moving on to the next thing.

one page website with css transition to sweep content in from alternating sides

I am trying to create a one page website with 7 navigation links. See my fiddle below.
The first navigation link is located in the top left corner, for now its text called "home". The other 6 links are located underneath my "middle" div.
I am trying to achieve the following effect:
the home page is always displayed upon landing
the 6 links underneath the "middle" div should appear from either the left side of the screen or right side simply depending on this logic: 1st transition enter screen from right side, 2nd transition enter screen from left side, all subsequent transitions to alternate sides.
Each transition should push the existing content off the screen instead of overlapping it.
If the navigation links are explored in sequence from page 1 to page 6, each time a link is clicked the transition should alternate sides. In my current fiddle (although not working correctly) the pages 1 through 6 will all enter the screen from right hand side and if you navigate backwards from 6 to 1 they all enter the screen from the left. This is not what I am looking for. I want alternating sides regardless of which link is clicked except home link in top left.
when the home link is clicked when viewing another links content the transition should appear from top of the screen and push the existing content off the bottom of the screen. This transition should happen behind all the other divs ie. header and footer.
If anyone is able to help me I would really appreciate it as this has taken me quite some time and research.
Here is my html:
<div class="main">
<div class="main_header">
<div id="navigation">
<a id="home_link" href="index.php">Home</a>
<form action="url" method="post" class="formTop">

<input type="password" class="login" value="Password" onFocus="if (this.value == 'Password') {this.value = '';}" onBlur="if (this.value == '') {this.value = 'Password';}" />

Here is my js
$(document).on("click", ".links", function () {
$("#middle").removeClass(); /* Remove all classes */
$("#middle").addClass("transition " + this.id + "_inside"); /* add 'transition' for effects and eg. 'home_inside' classes */
});
Here is my Fiddle
Thanks

I suggest using .animate() I had the same idea and when I tried it it worked perfectly also if you want to have the old ones pushed off use a <ul> inside a div with overflow: hidden; then on the li's use display: inline; and list-style-type: none;
Here is a working fiddle
http://jsfiddle.net/X4URc/3/

Here's an example of how to get this working page1-page6:
#middle.page2_inside #page2_content {
margin-left: 50%;
margin-top: -16px;
}
#middle.page3_inside #page3_content {
margin-left: 66.66%; // margin-left is [(pageNum-1)/pageNum]*100% = 100% * 2/3
margin-top: -64px;
}
#middle.page4_inside #page4_content {
    margin-left: 75%; // 100% * 3/4
margin-top: -112px;
}
#middle.page5_inside #page5_content {
margin-left: 80%; // 100% * 4/5
margin-top: -160px;
}
#middle.page6_inside #page6_content {
margin-left: 83.33%; // 100% * 5/6
margin-top: -208px;
}
