Thanks for your interest in contributing to Animate.css! Before contributing, please make sure you understand the guidelines provided here. Animate.css is widely used, so it’s important to maintain a high level of quality and to contribute with the interests of the community in mind.
Animations, like many facets of visual and interaction design, can be highly subjective. Maintaining a consistent library of animations in an active community can be difficult; these design guidelines are designed to help encourage thoughtful criticism of new animations that are proposed for Animate.css.
The animations in Animate.css should follow a few key principles:
- Animations should be subtle. Avoid creating animations that involve large translations, or span a natural duration of longer than 1 second.
- Animations should be tolerable. Related to subtlety, animations should be tolerable—seeing them repeatedly should not become too annoying or overbearing.
- Animations should not interfere with document flow or control/input availability. In other words, the absence of an animation should never reduce usability of a product: they should be non-critical and seen as “progressive enhancements”. Avoid animations that change properties such as
position
ordisplay
. - Animations should be helpful. They should be designed to guide users to a point of interest, ease natural reading order, or to communicate relationships between elements.
- Animations should feel familial. Avoid introducing animations that feel out-of-place compared to the existing set.
- Animations should feel natural. Animations should reflect, as much as is reasonable, motion that occurs in natural physics. Avoid extreme timing functions, and model animations on real-world events.
- Match the naming convention (camelCase, categorized [fades, bounces, etc])
- Indent with two spaces
- End each file with a blank line
