Setting height of child divequal to its parent div - javascript

I have a div tag in which i have a panel which is accordion. Now my div tag height is dynamic it depends on data and panel is fixed on top of div which will expand with some sub data on click. I want to set the height of my panel equals to its parent div. Note div height is dynamic.
.menuboxcontent {
background-color: deepskyblue;

text-align: center;

padding: 20px 10px;
margin: 0;
}
var boxheight = $('.menuboxcontent').height();
$('.collapse').on('show.bs.collapse', function() {
$(this).parent().find('.glyphicon-menu-down').removeClass('glyphicon-menu-down').addClass('glyphicon-menu-up');
$(this).parent().('.collapse').css('height', boxheight + 'px');
})
$('.collapse').on('hide.bs.collapse', function() {
$(this).parent().find('.glyphicon-menu-up').removeClass('glyphicon-menu-up').addClass('glyphicon-menu-down');
$(this).parent().('.collapse').css('height', (boxheight * 0.1) + 'px');

You could always just set the panel's height to inherit like height: inherit;
This makes your panel inherit the height of it's parent, which is the div with the menuboxcontent class. Your panel would have a height of 100% because you set it's parents height to 100%

Change input spinner number and with that change input value

I'm trying to make an item card for a web shop that sels food. What I'm trying to do is that on the first click on the button with the cart icon the amout of item is increased by +1 (now it is increasing by steps that I have set on input element). But I also want it to increase the value (weight/amount) of the product by the step that is defined on the input value and the cart icon has to change to the plus icon (That I managed to do). And for the minus button the logic is reversed... so i click the - button the value/weight goes down and amount goes down and if it reaches 0 they should dissaper.
EXAMPLE:
I click the cart icon the amount increases to 1 and value/weight increases to 0.25kg... if I click the cart button again the amount goes to 2 and weight increases to 0.5kg. Now if I click the - button the amount goes down to 1 and weight to 0.25kg and if I click it again the amount should go to 0 and weight to 0 and the button wit - icon and the input field should disappear.
MY PROBLEMS:
My first problem is that I cant manage to set the amount to increase
by 1 and value/weight by the defined step
My second problem is that my code keeps hiding the [-] button and
input field on every click not when it reaches 0
Is this approach even correct or have I overcomplicated the thing I'm
trying to do? Is there an easier solution to this?
I'm providing the jsfiddle in this link so that you can have a loot at my code and hopefully understand and help me out with a couple of my problems...

My javascript + jQuery:
$(document).ready(function () {
$("input[type='number']").inputSpinner({
decrementButton: "<strong class='decreaseInCart'>-</strong>",
incrementButton: "<strong class='addToCart'>+</strong>",
buttonsClass: 'btn-outline-secondary',
groupClass: 'flex-nowrap'
});
var $changedInput = $('#changedInput');
var $valueOnInput = $('#valueOnInput');
var $valueOnChange = $('.valueOnChange');
$changedInput.on('input', function (event) {
$valueOnInput.html($changedInput.val());
});
$changedInput.on('change', function (event) {
$valueOnChange.html($changedInput.val());
});
//Klik event ki zamenja sliko košarice z plus znakom
$('.btn-increment').click(function () {
$('.input-group-prepend').css('display', 'block');
$('.input-group-text').css('display', 'block');
$('.form-control').css('display', 'block');
$('strong').removeClass('addToCart');
});
$('.btn-decrement').click(function () {
$('.input-group-prepend').css('display', 'none');
$('.input-group-text').css('display', 'none');
$('.form-control').css('display', 'none');
$('strong').addClass('addToCart');
});
});
For the input field I'm using this plugin

You are just assigning the value from amount to kilos without processing it. You can solve it with this code $changedInput.val() * 0.25.
You are hiding the minus button without checking the value. You can solve it by if($changedInput.val() != 0).
You can combine selectors if you are performing the same action like this: $(".input-group-prepend, .input-group-text, .form-control").css('display', "none");.
You also have an issue with input values:
<input id="changedInput" data-name="Item One" data-price="8.78" type="number" value="" data-decimals="2" min="0.25" max="999" step="0.25"/>. Step should be 1 and min should 0.
Here is an example fixing all these issues:
$(document).ready(function() {
$("input[type='number']").inputSpinner({
decrementButton: "<strong class='decreaseInCart'>-</strong>",
incrementButton: "<strong class='addToCart'>+</strong>",
buttonsClass: "btn-outline-secondary",
groupClass: "flex-nowrap",
});
var $changedInput = $("#changedInput");
var $valueOnInput = $("#valueOnInput");
var $valueOnChange = $(".valueOnChange");
let $dataFactor = $changedInput.attr("data-factor");
$changedInput.on("input", function(event) {
$valueOnInput.html($changedInput.val())
})
$changedInput.on("change", function(event) {
$valueOnChange.html($changedInput.val() * $dataFactor);
})
//Klik event ki zamenja sliko košarice z plus znakom
$(".btn-increment").click(function() {
$(".input-group-prepend, .input-group-text, .form-control").css('display', "block");
$("strong").removeClass("addToCart");
});
$(".btn-decrement").click(function() {
if ($changedInput.val() != 0)
return;
$(".input-group-prepend, .input-group-text, .form-control").css('display', "none");
$("strong").addClass("addToCart");
});
});

Your second problem can be solve by wrapping these statements.
$(".btn-decrement").click(function(){
if (someValue === 0){
$(".input-group-prepend").css('display', "none");
$(".input-group-text").css('display', "none");
$(".form-control").css('display', "none");
$("strong").addClass("addToCart");
}
});

CSS deactivating href links with unrelated line, "left: 0;"

Two divs on my homepage contain nav elements: the .header-nav and the .visualizer.bars nav. For some reason my .header-nav links weren't active, and I've narrowed down the culprit to a single line in my css file: .bars {left:0;}.
When I remove this line, the links in my .header-nav work fine. I have no idea what's linking these two div elements, but I need that line in place for the visualizer effect to work properly.
Everything I've seen in my research indicates a problem with the JavaScript, but unlinking the JS doesn't affect the hrefs so I don't think that's it.
What can I do to keep all links active with the correct styling?

Jump on slideUp jQuery

I'm trying to create a material design Stepper using Materializecss and I'm almost there, but I'm having some strange issue with the slideUp animation on each step.
When it's just about to end, there is an abrupt jump. I prepared a jsFiddle for you to see, but I'm also writing the code in here:
https://jsfiddle.net/c3xLwzru/
HTML:
<div class="row">
<div class="col l8 m10 s12 offset-l2 offset-m1">
<h3 class="light center-align purple-text text-darken-4">Subscription</h3>
<div class="card">
<div class="card-content">
<ul class="stepper">
<li class="step">
<div class="step-title waves-effect waves-dark"><div class="number">1</div>Step 1</div>
<div class="step-content">
Example 1
<div class="step-actions">
<button class="waves-effect waves-dark btn" type="submit">SEGUINTE</button>
</div>
</div>
</li>
<li class="step">
<div class="step-title waves-effect waves-dark"><div class="number">2</div>Step 2</div>
<div class="step-content">
Example 2
</div>
</li>
<li class="step">
<div class="step-title waves-effect waves-dark"><div class="number">3</div>Step 3</div>
<div class="step-content">
Example 3
</div>
</li>
</ul>
</div>
</div>
</div>
</div>
CSS (adding to Materializecss):
ul.stepper {
max-width: 800px;
}
.step:not(:last-child) {
position: relative;
margin-bottom: 24px;
}
.step:not(:last-child).active {
margin-bottom: 36px;
}
.step-title {
margin: 0 -20px;
cursor: pointer;
margin-bottom: 8px;
padding: 12px 44px 24px 20px;
display: block;
}
.step-title:hover {
background-color: #F0F0F0;
}
.step.active .step-title {
font-weight: 500;
}
.step-title .number {
margin-right: 10px;
display: inline-block;
height: 28px;
width: 28px;
color: white;
background-color: rgba(0,0,0,0.3);
border-radius: 50%;
text-align: center;
line-height: 28px;
font-weight: 400;
}
.step.active .number {
background-color: #9C27B0;
}
.step-content {
display: none;
height: calc(100% - 132px);
width: inherit;
overflow: auto;
margin-left: 41px;
margin-right: 24px;
}
.stepper>.step:not(:last-child)::after {
content: '';
position: absolute;
top: 50px;
left: 13.5px;
width: 1px;
height: calc(100% - 24px);
background-color: rgba(0,0,0,0.1);
}
.stepper>.step.active:not(:last-child)::after {
height: calc(100% - 12px);
}
.step-actions {
display: none;
padding-top: 16px;
margin-right: 24px;
}
.step.active .step-actions {
display: block;
}
And JS, using jQuery:
$(document).on("click", '.stepper .step-title:not(.active)', function () {
$(this).parent().addClass('active');
$(this).next().stop().slideDown('slow');
$(".step.active").not($(this).parent()).find(".step-content").stop().slideUp('slow');
$(".step.active").not($(this).parent()).removeClass('active');
});
I don't know what to do anymore. I tried everything and I couldn't find a reason for them to jump, man.
Could you help me?

Remove margin-bottom: 8px on .step-title and add margin-top: 8px to .step-content.
It should stop abrupt jump

Center the DIV in DIV

Hello i have a next html code and CSS:
html,
body {
height: 100%;
padding: 0;
margin: 0;
}
.teaser {
width: 100%;
height: 25vh;
background-image: url("http://www.1zoom.me/big2/365/321125-alexfas01.jpg");
background-size: cover;
background-repeat: no-repeat;
background-position: 50% 50%;
}
a.menuButton {
padding: 0;
margin: 0;
width: 49.7%;
height: 33.33%;
float: left;
background-color: white;
border-collapse: collapse;
border: 1px solid #E6F0F0;
text-decoration: none;
position: relative;
color: black;
}
.rectangle {
padding: 0;
width: 70px;
height: 7px;
background: blue;
top: 0;
bottom: 0;
left: 0;
right: 0;
margin: auto;
}
.menuButtonContent {
position: absolute;
top: 0;
bottom: 0;
left: 0;
right: 0;
padding: 0;
height: 50%;
width: 50%;
background-color: red;
margin: auto;
}
.menuButtonContent h1 {
text-align: center;
}
.buttonsWrapper {
width: 100%;
height: 73vh;
}
.rectangle#citizenship {
background-color: #38CCBA;
}
.rectangle#fastsearch {
background-color: #00899B;
}
.rectangle#forillegals {
background-color: #D80C00;
}
.rectangle#soonillegals {
background-color: #FF8A00;
}
.rectangle#aboutapp {
background-color: #B8B8B8;
}
.rectangle#settings {
background-color: #626262;
}
<div class="teaser"></div>
<div class="buttonsWrapper">
<a class="menuButton" href="#">
<div class="menuButtonContent">
<h1>Citizenship</h1>
<div class="rectangle" id="citizenship"></div>
</div>
</a>
<a class="menuButton" href="#">
<div class="menuButtonContent">
<h1>Fast search</h1>
<div class="rectangle" id="fastsearch"></div>
</div>
</a>
<a class="menuButton" href="#">
<div class="menuButtonContent">
<h1>For illegals</h1>
<div class="rectangle" id="forillegals"></div>
</div>
</a>
<a class="menuButton" href="#">
<div class="menuButtonContent">
<h1>Soon illegals</h1>
<div class="rectangle" id="soonillegals"></div>
</div>
</a>
<a class="menuButton" href="#">
<div class="menuButtonContent">
<h1>About app</h1>
<div class="rectangle" id="aboutapp"></div>
</div>
</a>
<a class="menuButton" href="#">
<div class="menuButtonContent">
<h1>Settings</h1>
<div class="rectangle" id="settings"></div>
</div>
</a>
</div>
I have 2 problems:
1) I cannot find an apropriate solution to center the .menuButtonContent, it is centered horizontaly, but not vertically, on some screen sizes it gets centered vertically, but not at all - how can i center it?
2) The background-image: url doesn't get rendered, why?

To make an element vertically align centered, set the display property of the parent element as display:table; then set the element that has to be centered as display:table-cell; and vertical-align:midlle;.
.parent{
display:table;
}
.child-element-centered{
display:table-cell;
vertical-align:midlle;
}

Try using the calc() function in CSS
lets say the parent div is called "a" and its child was "b"
<div id="a" style="width:400px;height:400px;position:relative;">
<div id="b" style="position:relative;top:calc(25% - 100px);left:calc(25% - 100px);width:50%;height:50%;"></div>
</div>

first set the display of child divs to inline-block
then set the parent text-align to center. This will horizontally center your divs
and then use a "hack" to accomplish vertically aligning your child divs. See this fiddle for an example
