How to use CSS3 animations to improve UI & UX of a website?

Why Animate? 

Animation has greatly profited from the CSS3 development. You don't have to stress over learning JavaScript with a specific end goal to create beautiful animations. Nowadays, having a comfortable competency in CSS will afford you the ability to animate easily and effectively. And, it doesn't harm that there's a gigantic group of front end coders who readily share their codes with everybody.

Take adding or expelling things from a rundown, for example. (I've disentangled the action expected to add and uproot things for our reasons here.) When you add another thing to the rundown, numerous animations indicate that you've done as such effectively and offer a visual indication of its new position: adjacent things move off the beaten path to make room, the thing slides into its new residence, and the animated change out of sight shade highlights the new addition. The shade fades after some time as the thing gets to be less new, so center can be given to new actions if necessary. 

Similar animations give signs when evacuating a thing, making the interaction easier to take after and strengthening what has happened. In a more unpredictable rundown interaction—say, one where you can unreservedly drag and reorder things as you please—animation could help indicate where you can drop a thing, which things are active, and so on. 

As interactions get to be more than an arrangement of click, wait for new page, click on next thing, giving prompts and signs like this gets to be considerably more important. We're manipulating data, getting (and expecting) near real-time updates, and accomplishing more intricate tasks on the web. The touch screens in our pockets have adapted us to expect more keen and sophisticated interactions from all our screens. Besides, the nature of your animations pass on more personality than any static interaction could. There is a ton of potential force to be harnessed here! 
And yes, only for the sake of entertainment 

Talking about animation in a genuine light feels a bit bizarre at times because, well, animation should be fun, too. Keep in mind the impact of adding amaze and enjoyment. 

Animating UI’s like an ace 

Distinguishing the places where animation has utility is just half the battle. In case we're going to use animations in our outlines, we would be advised to make them great. Not very many web fashioners are also trained movement creators, however, in the event that we avoid these regular faux pas, we'll be well on our way to mastering UI animation. 

On the off chance that we were to animate each and every snippet of change in a given experience, we'd wind up creating intolerable wreckage. Yet there's a ton of room between no animation and all the animation. We have a considerable measure of space to examination. 

Animation ought to never hinder finishing a task. Indeed beautifully executed animation gets to be annoying fast in the event that it’s backing you off. The late Square update puts the site's navigation in a modal that animates into place. With a specific end goal to use the navigation, you have to wait for the modal to animate open, and then wait again for the menu alternatives to fade into place. 

10 Simple Animations that Improve UX and Why? 

How about we take a glance at some straightforward animations you can incorporate into your outline at this time that will decidedly affect user experience. 

1. Drift 
Drift is a delightful animation decision. Users are often liable to float over images. Capitalize on this by giving an animation that gives more information, for example, a site connection or add to cart button. 

2. Shake for void fields 
Animate.css allows you to delicately rouse action. It goes from the unobtrusive fade, to the unequivocal attention-grabbing wobble. This sort of animation suite is best used sparingly, and just when you require immediate attention. It shouldn't go unchecked out of sight, because it can be too distracting.
