Transition between size when parent div of child element changes - html

I have a menu that becomes a fixed menu when scrolling down the website. When that happens, the class r-header-fixed is added (and removed when scrolling back up). The logo that is inside my fixed menu is smaller than the one you see on pageload but when I scroll the size instantly changes. How can I ease the transition?
This is my css line:
.r-header-fixed .container .row .col-md-3 .r-logo .d-inline-block .logomurrays{
height:70px;
}
I tried adding transition: height 4s; to that, but the change is still instant.

Bootstrap modal: transition for height change

I have a Bootstrap (4) centered Modal with a fixed width and dynamic height based on the content within the modal (the default behavior).
Inside the modal, I have several divs that will be hidden or shown based on some conditions. The text inside the modal also change, and can be longer than expected. I don't know which of these components will be visible or what will be hidden, so the height can't be fixed.
Right now when a components is set as hidden the modal instantly changes its height. I want to use CSS transitions to smoothly change the height of the modal.
I have tried to apply this CSS, without success:
.modal {
transition: height 1s !important;
}
Surely I'm missing something due to my limited knowledge of the CSS animator. How can I apply a smooth transition?
If you control the elements that inside the modal with display: none, you can not transition smoothly and it is better to hide their with height:0 and
To transition smooth modal height, enter the following code:
.modal , .modal * {transition: all 0.2s ease}

Jumping slides in slick slider with variable width and center mode

I'm using the slick slider to show an centered slider on my site.
The slider should show one item in the center and display smaller items left and right.
To do this, I'm using centerMode and variableWidth.
The problem now is, that the slides are "jumping" after every change.
It looks good in the docs. What is my mistake?
Here's my code: http://jsfiddle.net/vv4j3uz2/1/
The only problem is that you have two different image's heights whether its parent slide has the center class or not.
.slider-header .slick-slide img {height: 520px; [...]}
.slider-header .slick-slide.slick-center img {height: 600px; [...]}
Make them the same and your issue is gone ;)
If you give the .slick-track some CSS animation transition it works well.
.slick-track { transition: all 0.3s ease; }

Vaadin: Force CSS-containers to fit full width after animation

I am developing with Vaadin 7 and wanted to create a sidebar, which can be toggled visible via button click. The sidebar-container appears / disappears with a CSS rotation animation and folds to the right.
All the components are placed in CSSLayouts and organized like this (Every container represents one Layout-object):
I want the mainContainer to take the full width of the root-container when the sidebar is toggled invisible. My problem is that the sidebarContainer only shows up if I give it a static width (e.g. 300px). When invisible, a white blank space remains where the sidebar used to be.
Here some pictures showing my idea of the result:
My orientation was the Vaadin Sampler, where the menu Button unfolds a sidebar and the main content gets moved to the left. Which possibilities exist to realize such a smooth container resizing animation?
Thanks in advance!
I figured out how to solve the problem with a combination of styling and Java code.
The button click event resizes the .sidebarContainer cssLayout. When the sidebar is toggled invisible, the layout width is set to 0.
The sidebar container adapts two animation CSS classes for the opening and closing animations, which are also directed by the button click event.
Java
public void buttonClick(ClickEvent event) {
if (sidebar.getStyleName().contains("sidebar-in"))
{
sidebar.removeStyleName("sidebar-in");
sidebar.setStyleName("sidebar-out");
sidebarContainer.setWidth(0,Unit.PIXELS);
return;
}
sidebar.removeStyleName("sidebar-out");
sidebar.setStyleName("sidebar-in");
sidebarContainer.setWidth(300,Unit.PIXELS);
}
To let the .mainContainer shift as smoothly as in the Vaadin sampler application, I gave the .sidebarContainer a transition attribute. Now, when this container is resized by the button click event, the CSS ease-function creates a width-changing movement and the flex-layout of the mainContainer makes it stick to that movement. The sidebar itself is a panel inside the .sidebarContainer.
CSS
.mainContainer {
display: flex;
flex-wrap: wrap;
align-items: flex-start;
flex: 1;
order: 1;
width: auto;
}
.sidebarContainer {
order: 2;
transition: width 1s ease;
-moz-transition: width 1s ease;
}
.sidebar-in{
animation: sidebarAnimationFramesIn ease 1s;
animation-iteration-count: 1;
transform-origin: 100% 50%;
animation-fill-mode:forwards;
width: 100%;
}
.sidebar-out{
animation: sidebarAnimationFramesOut ease 1s;
animation-iteration-count: 1;
transform-origin: 100% 50%;
animation-fill-mode:forwards;
width: 100%;
}
I realized the toggle-animation of the sidebar by adding Keyframes in CSS
The good and the bad of a CSSPanel is that it is a white table, where everything can be done, but still needs to be write (like css styling and such).
I can suggesto to take a look at HorizontalSplitPanel where you should block and hide the separator. It should listen perfectly when you decide to collapse a side.
I havent tasted it right now on your use case but i have used before and never had an issue. Give it a go!

Css animation not running after first run

I have 2 divs one for expanding content and one for heading text.
I expand them by changing a class on the parent element (via javascript) and then setting height/width to 0 and visibility to hidden
I'm trying to figure out why the css animation stops running after the first expansion and how to make the timing consistent.
I'm using max-height for the animation because I don't know the target height.
JSFiddle
[data-element] {
transition: max-height 4s ease;
}
.collapsed [data-element="collapsed"] {
max-height: 900px;
height: auto;
width: auto;
}
I got something working here, but the animation with max-height causes a delay, making this not an ideal solution.
removing some of this helped
height:auto;

Animating Flexbox with Media Queries?

I'm trying to create a website using flexbox, and one of the main features of the site is to hide the navigation bar, in this case the left panel in the JSFiddle, when the viewport is between 480px and 1023px. Currently it works, but the animation is very jumpy and it is not clear what is happening.
Right now I am trying to use a transition in css3, but that doesn't seem to animate anything at all...
Going from this:
aside {
-webkit-transition: all 1s ease;
width: 270px;
}
To this:
aside {
display: none;
}
No transition happens between the two states.
How can I animate the navigation disappearing and the main growing to fit the screen?
You can not animate Display in CSS as of today.
You can probably chain animation on some properties that can be animated. For instance the width and height of some flexboxes.
