Transition on Stretching Div

I have a div with some content in it, and I am showing a button with jQuery. I want to fade it in thus I used:
setTimeout(function() {
jQuery('#button').css('opacity', 1);
}, 100);
First, on html, I have set the button's html to display:none; opacity: 0 I have achieved showing/hiding button, however when it shows, it's making the div stretch instantly. Instead, I want the parent div to expand with transition.
I have created a Fiddle: https://jsfiddle.net/atg5m6ym/7450/ . In this example, when I press the trigger button, I want the button to fade in as well as applying transition on the parent div.

For optimal performance, when using transitions and animations in CSS, you should stick to opacity and transform instead of display: none; and width/height.
Will quote the comment I stated above:
The way you designed this is not ideal, you should not be using
display: none; in transitions or animations. This will cause redrawing
in your browser, and you cannot transition properties with binary
settings, display just switches between states (ex: none/block), not
between values like opacity does.
What you could do is separate your content, sharing the same background color to simulate it is the same container.
Then use transform and the scale() function.
Code Snippet:
jQuery('#trigger').click(function() {
jQuery('.bottom-content').addClass('open');
})
.top-content,
.bottom-content {
background-color: lightblue;
}
.bottom-content {
transform: scaleY(0);
transition: transform 250ms ease-in;
transform-origin: top;
}
.bottom-content.open {
transform: scaleY(1);
}
.bottom-content.open #otherButton {
opacity: 1;
}
#otherButton {
margin-top: 20px;
opacity: 0;
transition: opacity 10s;
transition-delay: 250ms;
/* Separated for clarity purposes, wait for parent transition to end before starting this one*/
}
<script src="https://www.addressfinder.co.nz/assets/v2/widget.js"></script>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="container">
<div id="content">
<section class="top-content">
<button id="trigger">
Trigger
</button>
<br />Lalala La
<br />Lalala La
<br />Lalala La
<br />
</section>
<section class="bottom-content">
<button id="otherButton">
Test Btn
</button>
</section>
</div>
</div>

The accepted answer is overkill. Just use .fadeIn() and forget the opacity and transition settings completely. If you want to have the div expand separate from the button, just apply the effect to the div and then trigger the button effect at the end of the div effect. This snippet does the same thing as the accepted answer without any of the CSS troubles:
$(function(){
jQuery('#otherButton').hide();
jQuery('#two').hide();
});
$('#trigger').click(function() {
$('#two').slideDown(2000, function(){
$('#otherButton').fadeIn();
});
})
#container, #two {
background-color: lightblue;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.0.0/jquery.min.js"></script>
<div id="container">
<div id="content">
<button id="trigger">Trigger</button>
<br>
Lalala La<br>
Lalala La<br>
Lalala La<br>
<div id="two">
<button id="otherButton">Test Btn</button>
</div>
</div>
</div>

You can combine the jquery:
jQuery('#trigger').click(function() {
jQuery('#otherButton').slideDown(300).css('opacity', 1);
})
Note that I used the slideDown() function rather than show(). Using a transition function allows you to set an execution time. show() simply toggles the css display property, but you can not transition the display property.
Updated Fiddle

Instead of adding CSS with jQuery, you can simply add a class instead.
Set this class to whatever properties you want on it, us as:
.is-visible {
opacity: 1;
}
Example Fiddle: https://jsfiddle.net/atg5m6ym/7456/
Now, CSS doesn't like to transition when switching display: none; so instead I have simply set the height: 0; and only applied necessary styling on the .is-visible class.

CSS: Change parent on focus of child

Let's say you have something like:
<div class="parent">
<input class="childInput" type="text" />
<div class="sibling"></div>
</div>
I want to change the appearance of the parent/siblings when the child receives focus. Are there any CSS tricks for doing stuff like this?
Edit:
The reason for my question is as follows:
I'm creating an Angular app which needs editable text fields. It should look like a label until it is clicked, at which point it should look like a normal text input. I styled the text field based on :focus to achieve this effect, but the text is cut off by text input's boundaries. I also used ng-show, ng-hide, ng-blur, ng-keypress and ng-click to switch between the label and the text input based on blurs, key presses and clicks. This worked fine except for one thing: After the label's ng-click="setEdit(this, $event)" changes the edit boolean used by ng-show and ng-hide to true, it uses a jQuery call to .select() the text input. However, it isn't until after the completion of the ng-click that everything is $digest'd, so the text input loses focus again. Since the text input never actually receives focus, using ng-blur to revert back to showing the label is buggy: The user has to click in the text input and then click out of it again to revert back to showing the label.
Edit:
Here's an example plunk of the issue: http://plnkr.co/edit/synSIP?p=preview

You can now do this in pure CSS, so no JavaScript needed 😁
The new CSS pseudo-class :focus-within would help for cases like this and will help with accessibility when people use tabbing for navigating, common when using screen readers.
.parent:focus-within {
border: 1px solid #000;
}
The :focus-within pseudo-class matches elements that either themselves
match :focus or that have descendants which match :focus.
Can I use...
You can check which browsers support this by visiting http://caniuse.com/#search=focus-within
Demo
fieldset {
padding: 0 24px 24px !important;
}
fieldset legend {
opacity: 0;
padding: 0 8px;
width: auto;
}
fieldset:focus-within {
border: 1px solid #000;
}
fieldset:focus-within legend {
opacity: 1;
}
<link href="https://stackpath.bootstrapcdn.com/bootstrap/4.1.3/css/bootstrap.min.css" rel="stylesheet" />
<div class="container">
<form>
<fieldset>
<legend>Parent Element</legend>
<div class="form-group">
<label for="name">Name:</label>
<input class="form-control" id="name" placeholder="Enter name">
</div>
<div class="form-group">
<label for="email">Email:</label>
<input type="email" class="form-control" id="email" placeholder="Enter email">
</div>
</fieldset>
</form>
</div>

There is no chance how to do that with CSS. CSS can style only siblings, children, etc. not parents.
You can use simply JS like this:
<style>
.parent {background: green}
.focused {background: red;}
</style>
<div class="parent">
<input class="childInput" type="text" />
<div class="sibling"></div>
</div>
<script>
$('.parent > *')
.focus(function() {
$('.parent').addClass('focused');
})
.blur(function() {
$('.parent').removeClass('focused');
});
</script>
http://jsfiddle.net/C4bZ6/
This code takes all direct children of .parent and if you focus one of them, class focused is added to parent. On blur, this class is removed.

You can use pure CSS to make the text input look like it's not a text input unless it is in focus
http://jsfiddle.net/michaelburtonray/C4bZ6/13/
input[type="text"] {
border-color: transparent;
transition-duration: 600ms;
cursor: pointer;
outline-style: none;
text-overflow: ellipsis;
}
input[type="text"]:focus {
border-color: initial;
cursor: auto;
transition-duration: 300ms;
}

Try the contenteditible attribute. This may require more work to turn it into usable form data however.
http://jsfiddle.net/michaelburtonray/C4bZ6/20/
<span class="parent" contenteditable>Click me</span>

You can style it even for focus-within and not(focus-within) like this (without using JavaScript => more accessible and faster):
.myform:not(:focus-within) button[type="submit"] {
display: none;
}
.myform:focus-within button[type="submit"] {
display: block;
}

Overlapping Divs and simplifying jquery code

first is trouble with my overlapped divs, they're supposed to be overlapping each other but the thing is that upon loading the page, the box-shadow style are overlapped too, which I do not want, and would like to fix it.
the box shadow i want for each div is box-shadow: 0 0 2px #acacac;
but upon loading the page since there are 3 divs overlapped together the box shadow looks like it's been set to box-shadow: 0 0 6px #acacac;.
second is trying to simplify my jquery code.I've been trying to figure out a way to just uncheck all selected radio buttons upon checking a specific radio button, rather than having a long line of jquery code. something in the line of "if this radio button checked, uncheck checked radio button"
heres the
Jsfiddle(http://jsfiddle.net/cQca5/3/)
hopefully I find a solution, thanks!

JS: Simple as that. Hide all the divs and show what you want.
$(document).ready(function(){
$('input[type="radio"]').click(function(){
$('.div_style').css('display','none');
$('#'+$(this).val()).fadeIn();
});
});
CSS: display:none in .div_style
.div_style{
position:absolute;
border:1px solid #acacac;
width:750px;
height:500px;
border-radius:2px;
box-shadow: 0 0 2px #acacac;
top:40px;
left:0px;
display:none;
background:#FFF;
}
#diva{
z-index:1;
}
#divb{
}
#divc{
}
HTML: the attr name should be the same. Display:block for the first div.
<div>
<label><input type="radio" name="radio" value="div1" checked> 1st</label>
<label><input type="radio" name="radio" value="div2"> 2nd</label>
<label><input type="radio" name="radio" value="div3"> 3rd</label>
</div>
<div class="div_style" style='display:block;' id="div1">div1</div>
<div class="div_style" id="div2">div2</div>
<div class="div_style" id="div3">div3</div>

Priority field in html form

I need to create a priority field in my HTML form. Currently i am using radio buttons but it does not suffice my needs. The radio button should change background color onclick depending on the level of priority. Also i am not able to read the values to the controller.
The priority field should change colors according to the matrix above. In the form only the first row is present for the priority field.
This is the HTML i am using for priority
` <input type="radio" id="1" class="priority">
<input type="radio" id="2" class="priority">
<input type="radio" id="3" class="priority">
<input type="radio" id="4" class="priority">
<input type="radio" id="5" class="priority">`
I am using spring MVC framework.
Any help would be appreciated

UPDATE: updated FIDDLE
add value attribute to the radio buttons like
<input type="radio" name="1" id="r1" value="a rating">
then some script to read the radio button values like:
var htmlStr = $(this).attr("value");
$(".indicator").html(htmlStr);
I've tried some workaround for the sake of "changing color" in this Fiddle
Added this html, to act as the radio buttons that changes color:
<div class="circ"></div>
<div class="circ"></div>
<div class="circ"></div>
<div class="circ"></div>
<div class="circ"></div>
with this css, to take it under the radio buttons:
.circ{
height: 12px;
width: 12px;
border-radius: 50%;
background: gray;
display: inline-block;
position: relative;
bottom: 20px;
margin-left: 5px;
margin-right: 4px;
}
Then add z-index: 9 to the radio button css rule to make it stay on top of the .circ divs and be clickable. Finally, add opacity: 0 to make it invisible, so the .circ divs under will appear on screen. Now you can change the color of the .circ divs accordingly using some script.
PS: You can't just edit radio button's background color, instead use background images

I am not sure if i understud your question correct, but if so this demo code (jsfiddle) might help.
(its just a demo, and would still have to be adapted for your needs)
It simply sets the color class on the Click event of every RadioButton.
CSS
.color1 {
background:red;
}
.color2 {
background:green;
}
.color3 {
background:yellow;
}
HTML
<div class="priority">
<input type="radio" name="1" id="1">
<input type="radio" name="1" id="2">
<input type="radio" name="1" id="3">
<input type="radio" name="1" id="4">
<input type="radio" name="1" id="5">
</div>
Script
$(function () {
$(".priority input").on("click", function () {
$(".priority").attr("class", "priority color" + this.id);
});
})
tested with Chrome 34+

As per your requirement you can use jQuery plugin Colourful rating system. It comes with good options so that you can set the color as required.
DEMO
example as follows:
the HTML
<ul id="rating">
<li>This is just a piece of crap</li>
<li>Nothing too new or interesting</li>
<li>Not bad, I like it</li>
<li>I would like to see more of this</li>
<li>This is the best thing I've seen</li>
</ul>
CSS
#rating { list-style:none; }
#rating li { display:inline; float:left; }
#rating li a { display:block; width:80px; height:80px; border:1px solid #888; background-color:#333;
text-indent:-9999px; box-shadow:0 0 5px #888; border-radius:40px; }
#ratinginfo { clear:left; width:350px; }
#ratinginfo p { text-align:center; padding:10px;
box-shadow:0 0 5px #888; border-radius:40px; }
After we're done loading jQuery and the Color plugin, we're ready to use jQuery to now animate the circles to the right colour and display the text.
// Variable to set the duration of the animation
var animationTime = 500;
// Variable to store the colours
var colours = ["bd2c33", "e49420", "ecdb00", "3bad54", "1b7db9"];
// Add rating information box after rating
var ratingInfobox = $("<div />")
.attr("id", "ratinginfo")
.insertAfter($("#rating"));
// Function to colorize the right ratings
var colourizeRatings = function(nrOfRatings) {
$("#rating li a").each(function() {
if($(this).parent().index() <= nrOfRatings) {
$(this).stop().animate({ backgroundColor : "#" + colours[nrOfRatings] } , animationTime);
}
});
};
// Handle the hover events
$("#rating li a").hover(function() {
// Empty the rating info box and fade in
ratingInfobox
.empty()
.stop()
.animate({ opacity : 1 }, animationTime);
// Add the text to the rating info box
$("<p />")
.html($(this).html())
.appendTo(ratingInfobox);
// Call the colourize function with the given index
colourizeRatings($(this).parent().index());
}, function() {
// Fade out the rating information box
ratingInfobox
.stop()
.animate({ opacity : 0 }, animationTime);
// Restore all the rating to their original colours
$("#rating li a").stop().animate({ backgroundColor : "#333" } , animationTime);
});
// Prevent the click event and show the rating
$("#rating li a").click(function(e) {
e.preventDefault();
alert("You voted on item number " + ($(this).parent().index() + 1));
});

Radio button show and hide div in wordpress

I am trying to make a page in wordpress (it is built within wordpress custom page tool in admin interface).
What i want is 3 radio buttons. 2 visable 1 hidden.
The hidden one should be auto checked so it displays the correct div. (Maybe not needed when i use z-index in css?)
When a user click one of the checkboxes it should hide the another 2 divs and display the correct div (notice they are on the same place on the page).
For some reson i cant get this to work in wordpress. Or if there would be another way of doing the same way i am open for it as well.
CSS:
#apDiv3 {
position:absolute;
left:405px;
top:53px;
width:485px;
height:434px;
z-index:12;
background-color: #000;
color: #F00;
}
#apDiv10 {
position:absolute;
left:405px;
top:53px;
width:485px;
height:434px;
z-index:11;
background-color: #000;
color: #F00;
}
#apDiv11 {
position:absolute;
left:405px;
top:53px;
width:485px;
height:434px;
z-index:11;
background-color: #000;
color: #F00;
}
<script>
$(document).ready(function(){
$("input[name='payway']").click(function() {
var test = $(this).val();
$(".desc").hide();
$("#"+test).show();
});
});
</script>
HTML/PHP:
<p>
<input type="radio" name="payway" value="apDiv10" />
pay2
<input type="radio" name="payway" value="apDiv3" checked="checked" style="display:none;">
</p>
<p>
<input type="radio" name="payway" value="apDiv11" />
Pay1
</p>
<div id="apDiv3" class="desc">
This is the standard div that should be visable
</div>
<div id="apDiv10" class="desc">
Shows this div when user click on checkbox pay2
</div>
<div id="apDiv11" class="desc">
Shows when user click checkbox pay1
</div>

It seems when i looked at the head.php file there was a script that dident work which made my script not to work at all.
Once i removed the script from the head it worked.
Thank you all!
