ceri-tooltip

a mobile-friendly tooltip.

Features:

• plain JS - no dependencies
• 28kB unzipped with animations - even smaller when using multiple ceri components
• themeable
• use in your markup - easy to reason about
• aware of the viewport - automatically changes opening direction to be visible
• use css margin to position tooltip

Demo

Positioning

There are two ways of positioning. The default is in-place, the other possibility is on body.

• The in-place positioning can be problematic when you have an overflow:hidden combined with a position:absolute|relative|fixed element in the parent chain and the tooltip is overflowing.
• the body positioning can be problematic when the parent is moving relative to body or when you depend on inheritance of styles.

Themes

• ceri-materialize

<button class=btn>hover or touch-hold</button>
<ceri-tooltip class=materialize>Information</ceri-tooltip>

Custom animation

• read the documentation of the animate mixin.
• read and understand the default enter and leave animation in src/tooltip.coffee
• you can provide a custom animation like this:

# application wide
CETT = require("ceri-tooltip")
CETT.prototype.enter = (o) -> # your new enter animation
CETT.prototype.leave = (o) -> # your new leave animation
window.customElements.define("ceri-tooltip", CETT)

# single instance
# get a ref to your instance of ceri-tooltip somehow
# then overwrite the animations directly
ceTT.enter = (o) -> # your new enter animation
ceTT.leave = (o) -> # your new leave animation
