In CSS transition shorthand is essential transition-delay? I would like to know if is possible to use shorthand without transition-delay...
Because i have a module on my website that minimize ces and i read that minification delete units to transition delay, and if is without unit transition doesn't work with firefox (for me also with chrome).. So:
So can i write in this way:
transition: font-size 2s ease-out; //without 0s of transition delay
Is possible ???
Thanks a lot and sorry for my english :)

I faced the issue with low fps while using backdrop-filter and transition on the same component.
.modal-background {
// some styles
backdrop-filter: blur(2px)
transition: all .15s linear
}
As simple as that. The animation is glitchy :( But if I comment out backdrop-filter line, things are getting better.
You can achieve a different but comparable effect by instead animating the backdrop-filter's opacity() like so:
.bg {
transition: backdrop-filter 0.2s;
backdrop-filter: blur(4px) opacity(0);
}
.bg.show {
backdrop-filter: blur(4px) opacity(1);
}
I have seen some minor graphical glitches when doing this in Chromium. But on the plus side, I've also found this approach to be much more performant than the alternative suggestion of animating a (non-backdrop) filter property's blur(). There's a trade-off to be made between responsiveness and graphical accuracy.
I believe, it's a very new property and can't be animated properly yet. You can always restructure something to make work this one instead: filter: blur(7px);
As Roman mentions
its a very new property. Until it got optimized, you have to look for alternatives. More specifically on "filter: blur(6px)":
<div id="root"/>
<div id="modal"/>
If you are trying to apply a backdrop on modal, don't. Go put some listeners on parent (#root) element checks if it has that child modal, apply filter on "#root" and enjoy.
I use the following CSS to animate the change in background color for a div:
#availability-button.red-add, #availability-button.red-remove, #availability-button.green-add, #availability-button.green-remove{
transition: background-color 2000ms linear;
}
#availability-button.red, #availability-button.red-add, #availability-button.red-add-active{
background-color: #c21807;
}
#availability-button.green, #availability-button.green-add, #availability-button.green-add-active{
background-color: #68af28;
}
The above works only one way - when you transition from green to red.
What is causing this?
Fiddle
You only need #availability-button.red and #availability-button.green. The animation life-cycle classes like red-add and red-remove are useful if you're using animations, but for transitions can be tricky since you're just transitioning the change in properties between selectors.
In this case, it seems like multiple selectors are matched in the red-* and green-* groups, which causes undefined behavior in how the transition is completed.
Updated Fiddle
IMHO there are 3 possible ways to declare an animation for certain HTML elements on the page:
* { transition: all .3s ease; } - Regarding lines of code, file size, and ease of use, I find this the most suiting solution to handle CSS animations on a page. But I do know using the asterisk selector has quite a heavy impact on performance, so this option doesn't seem like the most efficient one. Also, this sometimes causes for unwanted animations on objects where it's not needed.
.animated { transition: all .3 ease; } - Again regarding lines of code, file size and ease of use (in CSS), this looks like the optimal solution. We create a class specifically for animations, and just add this class to all elements we need an animation on. Variations can be made (adjusting the speed etc.) with other classes. But, this does require that every single HTML element you would like to animate should get this class, which means that when for some reason the classname changes one day, all these references should be updated.
.class1, .class2, .class3, ... { transition: all .3s ease; } - Another solution to this problem could be to have one giant selector for every HTML element in need of animation. This could be causing a giant CSS selector, which is not very file size friendly, nor very readable IMO. But, it does have some advantages too - there's only one place to be updated whenever an element needs animation.
So my question is:
What is the most efficient way to handle CSS animations on a HTML page?
I'm trying to get an compass sass animation running with endless rotation. Thats working but at the end of each rotation the item seems to slow down a little bit (like easing) but there's no easing set by myself and in documentation any value is set to false. What could be the reason for tht problem?
This is my animation made with compass animate:
#include keyframes(rotation) {
0% {
#include transform(rotate(0deg));
}
100% {
#include transform(rotate(359deg));
}
}
The animation-timing-function CSS property is set to ease by default. To override this and make your animation smooth you'll need to set this property to linear where you're calling the animation:
animation-timing-function: linear;
Is there a way to target a specific CSS Transform property (such as Rotate(), Scale(), TranslateX()) with the Transition property? Something along the lines of:
transition: 200ms transform-Rotate, 500ms transform-TranslateX;
No. The CSS transition spec states that only single CSS properties can be used in the transition-property field. transform is a CSS property. Rotate(), Scale(), etc, are transform functions, not CSS properties.
