The Zen Garden aims to excite, inspire, and encourage participation.

To begin, view some of the existing designs in the list. Clicking on any one will load the style sheet into this very page. Yes, really. CSS allows complete and total control over the style of a hypertext document. The only way this can be illustrated in a way that gets people excited is by demonstrating what it can truly be, once the reins are placed in the hands of those able to create beauty from structure.

Designers and coders alike have contributed to the beauty of the web; we can always push it further. Strong visual design has always been our focus. You are modifying this page, so strong CSS skills are necessary too, but the example files are commented well enough that even CSS novices can use them as starting points.

You may modify the style sheet in any way you wish, but not the HTML. Send us a link to an archive of that file and all associated assets, and if we choose to use it we will download it and place it on our server. Why participate? For recognition, inspiration, and a resource we can all refer to showing people how amazing CSS really can be. It means that you can have a slow-motion or time-lapse effect with a javascript one-liner:.

Even though some aging browsers do not support custom properties, Animate. The provided delays are from 1 to 5 seconds. You can customize them setting the --animate-delay property to a longer or a shorter duration:.

You can also customize the animations duration through the --animate-duration property, globally or locally. This will affect both the animations and the utility classes. Notice that some animations have a duration of less than 1 second. As we used the CSS calc function, setting the duration through the --animation-duration property will respect these ratios.

So, when you change the global duration, all the animations will respond to that change! You can customize them by setting the --animate-repeat property to a longer or a shorter value:.

Don't forget to read the best practices section to make the best use of repeating animations. Animations can greatly improve an interface's UX, but it's important to follow some guidelines to not overdo it and deteriorate the user experience on your web-things. Following the following rules should provide a good start. You should avoid animating an element just for the sake of it. Keep in mind that animations should make an intention clear. Animations like attention seekers bounce, flash, pulse, etc should be used to bring the user's attention to something special in your interface and not only as a way to bring "flashiness" to it.

Entrances and exit animations should be used to orientate what is happening in the interface, clearly signaling that it's transitioning into a new state. It doesn't mean that you should avoid adding playfulness to the interface, just be sure that the animations are not getting in the way of your user and that the page's performance is not affected by an exaggerated use of animations.

Avoid it as it won't bring much value to the user and will probably only cause confusion. Besides that, there is a good chance that the animations will be junky, culminating in bad UX. There were some reports pointing out that this could trigger some weird browser bugs. Besides, making the whole page bounce would hardly provide good value to your UX.

If you indeed need this sort of effect, wrap your page in an element and animate it, like this:. Even though Animate. It will just distract your users and might annoy a good slice of them. So, use it wisely! All the Animate. You can read more about it here. Since version 3. This is a critical accessibility feature and should never be disabled!

This is built into browsers to help people with vestibular and seizure disorders. If your web-thing needs the animations to function, warn users, but don't disable the feature.
