Creating a Bubble Point Tooltips with CSS3 and jQuery
Chris Coyier shares a tutorial that creates a bubble point tooltips with CSS3 and jQuery. Note that its demo will not work on Opera.
To start with, here’s the HTML:
<a href="#" title="Hi, I'm a tooltip thingy.">link</a>
Givje the link a title attribute.
jQuery:
$("article a[title]").tooltips();
The plugin will do the following: loop through each link; make div.tooltip for each, text inside that matches it links the title attribute; remove links title attribute; when link is hovered on, it positions the tooltip accordingly and slides it to be visible; when link is hovered off, it slides the link out of visibility.
Here’s the massive code dump:
// IIFE to ensure safe use of $
(function( $ ) {
// Create plugin
$.fn.tooltips = function(el) {
var $tooltip,
$body = $('body'),
$el;
// Ensure chaining works
return this.each(function(i, el) {
$el = $(el).attr("data-tooltip", i);
// Make DIV and append to page
var $tooltip = $('<div data-tooltip="' + i + '">' + $el.attr('title') + '<div></div></div>').appendTo("body");
// Position right away, so first appearance is smooth
var linkPosition = $el.position();
$tooltip.css({
top: linkPosition.top - $tooltip.outerHeight() - 13,
left: linkPosition.left - ($tooltip.width()/2)
});
$el
// Get rid of yellow box popup
.removeAttr("title")
// Mouseenter
.hover(function() {
$el = $(this);
$tooltip = $('div[data-tooltip=' + $el.data('tooltip') + ']');
// Reposition tooltip, in case of page movement e.g. screen resize
var linkPosition = $el.position();
$tooltip.css({
top: linkPosition.top - $tooltip.outerHeight() - 13,
left: linkPosition.left - ($tooltip.width()/2)
});
// Adding class handles animation through CSS
$tooltip.addClass("active");
// Mouseleave
}, function() {
$el = $(this);
// Temporary class for same-direction fadeout
$tooltip = $('div[data-tooltip=' + $el.data('tooltip') + ']').addClass("out");
// Remove all classes
setTimeout(function() {
$tooltip.removeClass("active").removeClass("out");
}, 300);
});
});
}
})(jQuery);
