React- hover effect to hide div doesn't work

React- hover effect to hide div doesn't work - javascript

I am trying to use :hover in css to show/hide the display of one of my divs when I hover over another div, but for some reason it's not working. I got it to work on other components but for some reason it's not working for this instance. Can't figure out what I did wrong. please let me know what I'm doing wrong so I can fix my mistake
JSX
render() {
return (
<div className='row'>
<div className='container-job' onClick={this.test}>
<div className='row'>
<div className='job-title'>
{this.props.jobs_info.title}
</div>
</div>
<div className='row wrapper'>

.delete-container-job {
position: relative;
background-image: linear-gradient(to right, #4639a7, #78019c);
height: 100px;

}
#trash {
font-size: 22px;
color: white;
display: inline-block;
margin-top: 40px;
}
.center {
text-align: center;
}

You need to use general sibling combinator to apply a style on .delete-container-job when .container-job is hovered on.
.container-job:hover ~ .delete-container-job {
display: block !important;
}

How can I stop my center div from changing position after I SlideUp another divs?

I'm creating simple page with a <header> and a <section>. In the section I have 3 divs and I am positioning them with display: flex; and justify-content: space-between.
The problem is that I also use JS slideToggle() on two of them (extreme ones). It is changing the layout of my center div after they are going up. How can I do it so that my center div doesn't change position after one of the others is slid up?
$(document).ready(function() {
$('#playlist').click(function() {
$('#nav').slideToggle();
});
});
$(document).ready(function() {
$('#songs').click(function() {
$('#listSongs').slideToggle();
});
});
section {
display: flex;
justify-content: space-between;
}
#listSongs {
margin-top: 50px;
height: 550px;
background-color: black;
border-radius: 5px;
font-size: 25px;
width: 200px;
}
#listSongs p {
margin-top: 5px;
width: 200px;
text-align: center;
overflow: hidden;
height: 35px;
line-height: 50px;
color: white;
}
#player {
color: red;
}
#nav {
margin-top: 50px;
height: 550px;
background-color: black;
border-radius: 20px;
width: 200px;
}
.hidden {
margin-top: 50px;
height: 550px;
background-color: black;
border-radius: 20px;
width: 200px;
visibility: hidden;
}
#nav p {
text-align: center;
}
#nav ul {
list-style-type: none;
text-align: left;
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<section>
<div id="listSongs">
<p>Authors:</p>
<div class="after"></div>
</div>
<div id="player">
<p>something</p>
</div>
<div id="nav">
<p>something</p>
</div>
</section>

The issue is because when the slideUp/slideDown/slideToggle methods complete, they set display: none on the target element. This is what causes the layout of your page to shift.
To workaround, and improve the animation, you can use CSS instead. Use the transition property to animate the height setting. Then you can toggle a class which sets height: 0 on the target element. Try this:
$(document).ready(function() {
$('#playlist').click(function() {
$('#nav').toggleClass('hide');
});
$('#songs').click(function() {
$('#listSongs').toggleClass('hide');
});
});
body { background-color: #CCC; }
section {
display: flex;
justify-content: space-between;
}
section > div.panel {
margin-top: 50px;
height: 550px;
background-color: black;
border-radius: 5px;
font-size: 25px;
width: 200px;
transition: height 0.4s;
overflow: hidden;
}
section > div.panel.hide {
height: 0;
}
section > div.panel p {
margin-top: 5px;
width: 200px;
text-align: center;
overflow: hidden;
height: 35px;
line-height: 50px;
color: white;
}
#player {
color: red;
}
#nav {
border-radius: 20px;
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<button id="playlist">Playlist</button>
<button id="songs">Songs</button>
<section>
<div id="listSongs" class="panel">
<p>Authors:</p>
<p>lorem ipsum</p>
<div class="after"></div>
</div>
<div id="player">
<p>something</p>
</div>
<div id="nav" class="panel">
<p>something</p>
</div>
</section>
Note that I also rearranged some of the CSS to make it more generic with less repetition.

Getting an arrow to point at a specific (x, y) point

Hello I'm attempting to to have two arrows pointing at a specific (x, y) point or in the general area of a button.
I would like two arrows coming from each of the boxs pointing in the general area of the button. I can do this fine with regular css on certain screens but when the screen is resized or smaller then the arrows no longer point to the button. I'm just trying to figure out a good way to handle this.
So really what I'm asking is what would be good way to go about having two arrows appended after 2 divs pointing at the same point. (The Red Square)

I'm not really a math enthusiast, i managed to find a formula on the internet to do what you wanted.
Source Pen Instead of following the mouse i made it so it follows the button
PS: I removed the the html on the right for the sake of this explanation.
i know it's not a complete answer, but you can adjust it from here.
window.onresize = pointing;
function pointing() {
let point = document.querySelector('.data-source-button');
let rad = Math.atan2(point.offsetLeft, point.offsetTop);
let left = (rad * (20 / Math.PI) * -5) + 60;
document.querySelector('.leftArrow').style.transform = "rotate(" + left + "deg)"
}
pointing();

Keeping elements' hover style active when clicked on

I am making a selection panel and I am having a hard time figuring out an aspect to it. There are nine boxes and I want the user to be able to click the boxes and when clicked for the hover's format to stay present and then ideally some sort of checkmark or something added into the border of the box. I am completely unsure of how to get the boxes' hover font effect to stay when I take the mouse off.
Does anyone know how I can do this?
#project-scope-container {
margin-top: 70px;
margin-left: 9%;
width: 75%;
height: 300px;
}
#project-scope-title {
font-size: 1.2em;
font-weight: bold;
margin-bottom: 15px;
}
.project-option-boxes {
display: inline-block;
border: 1px solid #45ba95;
padding: 20px 0px;
margin: 12px 20px 12px 0px;
width: 30%;
text-align: center;
font-size: 1.2em;
color: #45ba95;
cursor: pointer;
}
.project-option-boxes:hover {
background-color: #45ba95;
color: #FFF;
}
<div id="project-scope-container">
<div id="project-scope-title">PROJECT SCOPE</div>
<div class="project-option-boxes">BRANDING & IDENTITY</div>
<div class="project-option-boxes">WEB DESIGN</div>
<div class="project-option-boxes">RESPONSIVE/MOBILE</div>
<div class="project-option-boxes">MARKETING ASSETS</div>

<div class="project-option-boxes">SEO OPTIMIZATION</div>
<div class="project-option-boxes">MONTHLY SUPPORT</div>
<div class="project-option-boxes">WEB DEVELOPMENT</div>
<div class="project-option-boxes">ECOMMERCE</div>
</div>

Create another class name that hold the same css style when hovering, and add those class into clicked element or use toggleClass like following example :
$('.project-option-boxes').click(function() {
$(this).hide().toggleClass('box_focused').fadeIn('slow');
});
#project-scope-container {
margin-top: 70px;
margin-left: 9%;
width: 75%;
height: 300px;
}
#project-scope-title {
font-size: 1.2em;
font-weight: bold;
margin-bottom: 15px;
}
.project-option-boxes {
display: inline-block;
border: 1px solid #45ba95;
padding: 20px 0px;
margin: 12px 20px 12px 0px;
width: 30%;
text-align: center;
font-size: 1.2em;
color: #45ba95;
cursor: pointer;
}
.project-option-boxes:hover {
background-color: #45ba95;
color: #FFF;
}
.box_focused {
background-color: #45ba95;
background-image : url("http://findicons.com/files/icons/2232/wireframe_mono/48/checkbox_checked.png");
background-position: right top;
background-repeat: no-repeat;
color: #FFF;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="project-scope-container">
<div id="project-scope-title">PROJECT SCOPE</div>
<div class="project-option-boxes">BRANDING & IDENTITY</div>
<div class="project-option-boxes">WEB DESIGN</div>
<div class="project-option-boxes">RESPONSIVE/MOBILE</div>
<div class="project-option-boxes">MARKETING ASSETS</div>
<div class="project-option-boxes">HTML5 ANIMATION</div>

<div class="project-option-boxes">MONTHLY SUPPORT</div>
<div class="project-option-boxes">WEB DEVELOPMENT</div>
<div class="project-option-boxes">ECOMMERCE</div>
</div>

You can use the following example by using JQuery and using .hover and .addClass():
$(".project-option-boxes").hover(function()
{
$(this).addClass("active");
});
#project-scope-container {
margin-top: 70px;
margin-left: 9%;
width: 75%;
height: 300px;
}
#project-scope-title {
font-size: 1.2em;
font-weight: bold;
margin-bottom: 15px;
}
.project-option-boxes {
display: inline-block;
border: 1px solid #45ba95;
padding: 20px 0px;
margin: 12px 20px 12px 0px;
width: 30%;
text-align: center;
font-size: 1.2em;
color: #45ba95;
cursor: pointer;
}
.project-option-boxes:hover {
background-color: #45ba95;
color: #FFF;
}
.active {
background: #45ba95;
color: white;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<div id="project-scope-container">
<div id="project-scope-title">PROJECT SCOPE</div>
<div class="project-option-boxes">BRANDING & IDENTITY</div>
<div class="project-option-boxes">WEB DESIGN</div>
<div class="project-option-boxes">RESPONSIVE/MOBILE</div>
<div class="project-option-boxes">MARKETING ASSETS</div>
<div class="project-option-boxes">HTML5 ANIMATION</div>
<div class="project-option-boxes">SEO OPTIMIZATION</div>
<div class="project-option-boxes">MONTHLY SUPPORT</div>
<div class="project-option-boxes">WEB DEVELOPMENT</div>
<div class="project-option-boxes">ECOMMERCE</div>
</div>

You can create a class with the same style as the hover, and when one box is clicked, you can add this class to the box.
.project-option-boxes.active {
background-color: #45ba95;
color: #FFF;
}
and to give the class to the boxes,
$(document).on('click', 'project-option-boxes', function (e) {
$(this).toggleClass('active');
}

Spacing between images

I have 3 images side-by-side, I would like to know how to get some spacing between them. I have tried everything, margins, padding and I don't know what to do.
.content1 {
background-image: url("http://www.thefreeloves.com/prototype/test/wp-content/uploads/2014/02/album-title.jpg");

You set your wrapping div's to 31% but you didn't change the size of your images so they were flowing outside the wrappers. If you set Overflow: hidden; on your album1, album2 and album3 div's you'll see that your margins are working on the divs but you'll only see part of your images. if you set the imgs themselves to a width of 100% as below you'll see it works.
.content1 {
background-image: url("http://www.thefreeloves.com/prototype/test/wp-content/uploads/2014/02/album-title.jpg");
color: white;
text-align: center;
width: 100%;
height: 20%;
display: block;
float: left;
}
.text1 {
font-family: "Goudy Old Style", Optima, sans-serif;
font-size: 40px;
margin-bottom: 0;
margin-top: 45px;
}
.text2 {
font-size: 30px;
color: #6CB9D9;
}
.album1 {
float: left;
width: 31%;
text-align: center;
margin: 1%;
}
.album2 {
display: inline-block;
width: 31%;
text-align: center;
margin: 1%;
}
.album3 {
float: right;
width: 31%;
text-align: center;
margin: 1%;
}
.album {
width: 100%;
overflow: hidden;
background-color: #191919;
}
.album img { width: 100%; }
<div class="content1">
<h3 class="text1">Our Latest Album<span class="slash"> / </span><span class="text2">Fresh from the house of Music Club Band</span></h3>
</div>
<div class="album">
<div class="album1">
<img src="http://www.thefreeloves.com/prototype/test/wp-content/uploads/2015/02/FDA9133-650x385.jpg" alt="album1">
</div>
<div class="album2">

<div class="album3">

</div>
</div>

In each div tag, just place the following style = "margin-right: 20px;". So for example, for the first image, change it ot this
div style = "margin-right: 20px;" class="album1">

You don't need to use float, you can simply set the display of the albums to inline-block, and set the text-align of their parent to center. Note that the three images there are too wide to be in one line, so you'll have to adjust that yourself.
.album1 img, .album2 img, .album3 img {
//set img width and height here
}
.album1 {
display: inline-block;
//add padding/margin here
}
.album2 {
display: inline-block;
//add padding/margin here
}
.album3 {
display: inline-block;
//add padding/margin here
}
.album {
width: 100%;

separate div to 3 columns

I asked same question 2 days ago but now i still don't get it.
I have 1 div and i want it to be separate into 3 columns of div. I know how to do this for 2 column but, when i am trying 3 column(right, center and left) i get this:
Problem: The pink square is not in the center
Here is my code:
HTML:
<div id="our_services" class="container">
<h1>המוצרים שלנו</h1>
<div id="try">
<div id="product1">
</div>
<div id="product2">
</div>
<div id="product3">
</div>
</div>
</div>
CSS:
#our_services {
/*height: 450px;*/
text-align: center;
font-family: "open_sans_hebrewregular", "alefregular",arial,"Times New Roman";
color: black;
background-color: rgb(224,224,224);
overflow: auto;
margin: auto;
}
#try {
background-color: orange;
width: 50%;
height: 50%;
margin: auto;
}
#product1 {
width: 30%;
height: 75%;
background-color: green;
float: right;
margin: 5px;
}
#product2 {
width: 30%;
height: 75%;
background-color: pink;
float: right;
margin: 5px;
}
#product3 {
width: 30%;
height: 75%;
background-color: blue;
float: left;
margin: 5px;
}

Try with display:inline-block; instead.
exemple

#our_services {
/*height: 450px;*/
text-align: center;
font-family: "open_sans_hebrewregular", "alefregular", arial, "Times New Roman";
color: black;
background-color: rgb(224, 224, 224);
overflow: auto;
margin: auto;
}
#try {
background-color: orange;
width: 50%;
height: 50%;
margin: auto;
}
#product1 {
width: 30%;
height: 75%;
background-color: green;
float: left;
margin: 1.5%;
}
#product2 {
width: 30%;
height: 75%;
background-color: pink;
float: left;
margin: 1.5%;
}
#product3 {
width: 30%;
height: 75%;
background-color: blue;
float: left;
margin: 1.5%;
}
<div id="our_services" class="container">
<h1>המוצרים שלנו</h1>
<div id="try">
<div id="product1">
afs
</div>
<div id="product2">
asf
</div>
<div id="product3">
asf
</div>
</div>
</div>
You had float right as well on one of the boxes

use float left to 1st and 2nd div also. and give margin on percentage. I think this will solve your problem.

I don't know of any way you can do this purely with html/css techniques. You can arrange the items with javascript after the dom (or this part at least) has loaded.
On the other hand, this gets you a little closer to what you want, although the distances between rows won't be equal to the distances between firs/last row and beginning/end of the orange rectangle:
<div id="our_services" class="container">
<h1>המוצרים שלנו</h1>
<div id="try">
<div class="smth">
<div id="product1" class="product">
</div>
</div>
<div class="smth">
<div id="product2" class="product">
</div>
</div>
<div class="smth">
<div id="product3" class="product">
</div>
</div>
</div>
<style>
#our_services{
/*height: 450px;*/
text-align: center;
font-family:"open_sans_hebrewregular", "alefregular",arial,"Times New Roman";
color: black;
background-color: rgb(224,224,224);
overflow: auto;
margin: auto;
}
.smth {
width: 33%;
height: 75%;
float: left;
}
#try{
background-color:orange;
width:50%;
height:50%;
margin:auto;
}
.product {
width: 90%;
height: 100%;
margin: auto;
}
#product1{
background-color:green;
}
#product2{
background-color:pink;
}
#product3{
background-color:blue;
}
</style>
</div>

As far as I understand:
If you don't want any spaces between you'd have to set the width property to (100/3)%
It all depends on your layout of what you want, if you want margin spaces between them all so that they're equally spaced between each other and the edges of their container div you'll have to work out what to do there. So in the case now you have 30% width for each, that leaves you with 10% spacing width which you can spread to 2.5% for margin-left: of your first 2 divs and then for the 3rd div use 2.5% for margin-right: (for a space between the right side and the 3rd div) margin-left:
But as I said, it all depends on what exactly you want for your layout, so if this doesn't answer your question could you tell me more about your expected layout?
If you want a very simple fix based off of what you have at the moment you could set the margin: property to auto and that should center the middle div between what you have now.
Edit: You should also edit the float properties so that they all float one way.

Check the example below:
Code:
#our_services {
text-align: center;
font-family: "open_sans_hebrewregular", "alefregular", arial, "Times New Roman";
color: black;
background-color: rgb(224, 224, 224);
overflow: auto;
margin: auto;
}
#try {
background-color: orange;
width: 50%;
height: 50%;
margin: auto;
}
#product1 {
width: 31%;
height: 200px;
background-color: green;
float: left;
margin: 1%;
}
#product2 {
width: 31%;
height: 200px;
background-color: pink;
float: left;
margin: 1%;
}
#product3 {
width: 31%;
height: 200px;
background-color: blue;
float: left;
margin: 1%;
}
<div id="our_services" class="container">
<h1>המוצרים שלנו</h1>
<div id="try">
<div id="product1">
</div>
<div id="product2">
</div>
<div id="product3">
</div>
</div>
</div>
Example

add the following css:
html, body {
width: 100%;
height: 100%;
}
and add the following properties to #our_services css:
width: 100%;
height: 100%;
further set box-sizing: border-box; and margin: 0% 0% 0% 2.5%; (top as you need, right 0%, bottom as you need and left 2.5%) for the prouctu divs. Btw. you should extract common style to a product class and apply the class on the product divs...

One nice solution is to use display:table and display:table-cell. Which will works for 2 and 3 div both.
HTML:
<div id="our_services" class="container">
<h1>המוצרים שלנו</h1>
<div id="try">
<div id="product1" class="product">
</div>
<div id="product2" class="product">
</div>
<div id="product3" class="product">
</div>
CSS:
#our_services {
background-color: rgb(224, 224, 224);
color: black;
font-family: "open_sans_hebrewregular","alefregular",arial,"Times New Roman";
height: 450px;
margin: auto;
overflow: auto;
text-align: center;
}
#try {
background-color: orange;
display: table;
height: 50%;
margin: auto;
width: 50%;
border-collapse: separate;
border-spacing: 10px;
}
.product{
display: table-cell;
height: 75%;
margin: 5px;
width: 30%;
}
#product1 {
background-color: green;
}
#product2 {
background-color: pink;
}
#product3 {
background-color: blue;
}
