animate | Simple animation library | Animation library

I am trying to add a loading spinner to a web application where I have been provided with an animated gif that should be used as the icon. Right now I'm doing this with a div that is initially hidden via CSS and then is shown when I want to indicate loading. I'm using the following CSS on this div so that when its shown the loading gif appears in the center of the screen

Good morning,

I am creating an animation by connecting 6 nodes coordinates at 10 different time steps.

I start with a test: I first create a static plot for a time equal to 2 (for example) and I get the exact static plot that I am expecting: all and only the consecutive nodes are connected.

Then I create the animation. Unfortunately, the animated plot connects the nodes in the wrong way. You can see that the animation connects the consecutive nodes, but also the second and the second to last nodes.

Any idea why? Thanks

I have a navbar and sidebar component in my nextjs app. In my index component I'm using useState to show and hide sidebar on mobile device.
It works perfectly fine but I want to add animation when user clicks on hamburger menu, the sidebar should be animated left to right and when clicked on close icon it should go back to right to left. FYI I am using tailwind css.

Here's the code:
indexjs file:

I know how to create a panResponder but im not sure how to create multiple instances of it. for eg. I have an array of elements that moves independently and i have to attach each reponders respectively to the element to get the layout values from it. Any help would be appreciated been stuck for long time.

I'm new to gganimate and was having difficulty figuring out how to do this.

I'd like to show the spread in two different levels of a variable by animating colour transitions. I want to show this by having the narrow level transition through a smaller range of colours than the wider level in the same amount of time. Is this possible?

Here's the reproducible example I have up-to now.

I am trying to dynamically add items to the list in Flutter so this list runs indefinitely. (I am trying to achieve this using a ListView.builder and the Future class).

The end-effect I am seeking is an endless auto-scrolling of randomly generated images along the screen at a smooth rate (kind of like a news ticker).

Is this possible? I have been reworking for ages (trying AnimatedList etc) but cant seem to make it work!

Would love any help to solve this problem or ideas.

I am currently a bit stuck! Lets say, have a grid of shapes (nested For-Loop) and I want to use a wave to animate it. The wave should have an offset. So far, i can achieve it. Currently the offset affects the Y-axis … But how can I manage to have a RADIAL offset – you know – like the clock hand, or a radar line… I really would like the offset to start from (width/2, height/2) – and then walks around clockwise. Here is my code and the point where I am stuck:

I am trying to implement this code below to catch PDF downloads inside a WKWebView:

I am investigating if the header in react-navigation can be animated similar to the most widely used social applications like Twitter, etc.

For this purpose recently, I encountered coinbase's example which is given here.

My questions are:

• In general, how the react-navigation header can be animated?
• Specifically, how to blend the Coinbase example with the react-navigation?

Similarly, I could not find any clean example for react-navigation usage with react-navigation-collapsible either.

So any atomic example code is appreciated.
