Create tooltips with ease, without JavaScript.

First, include the stylesheet at the top of your page.

<link rel="stylesheet" href="path/to/tippy.min.css">

For the simplest case, add the property data-tippy to an element with your tooltip text as the value. You can do this to links, spans, divs, and even buttons. (Well, in most browsers. We'll get to that.)

<button data-tippy="I am a tooltip!">...</button>
<a href="http://www.google.com" data-tippy="Link to Google">...</a>
<span data-tippy="Hello world">...</span>
<div data-tippy="Full width element">...</div>

By default, tooltips appear below the element to which they belong. By including the data-tippy-pos property, you can control how they appear. There are four potential values: "up", "down", "left", and "right".

<button data-tippy="I am a tooltip!" data-tippy-pos="up">
<button data-tippy="I am a tooltip!" data-tippy-pos="down">
<button data-tippy="I am a tooltip!" data-tippy-pos="left">
<button data-tippy="I am a tooltip!" data-tippy-pos="right">

The tooltips don't have much by way of default animation. They fade in, but that's it. There are two optional animation types, however. Include the data-tippy-animate property and one of two values, "slide" or "bubble".

Tippy.css has been tested in Internet Explorer 9-11 and the latest versions of Chrome, Firefox, Edge (yay Windows 10 Insider program), Vivaldi (my browser of choice), and Safari.

• Tooltips are created by using the ::before and ::after pseudo-elements, so tooltips on any element that doesn't have those, like images or input fields, won't appear.

You can work around this by wrapping the element in a span or a div, though, like this:

<div data-tippy="Super awesome picture">
   <img src="cats-rule.jpg">
</div>

• If your stylesheet is using pseudo-elements on certain elements, you will run into conflicts. This will result in weird behavior or non-working tooltips.

• HTML inside tooltips will not work, so don't even try.

• Tooltips don't work on <button> elements in Internet Explorer. I don't know why. :/

• The bubble animation uses the clip-path property, and (as of this writing) only works in Chrome, Vivaldi, and Safari.

• Tooltips on links that underline on hover get underlined in Edge.

• Tooltips on buttons get included in the focus outline.
  You can override this behavior with this code:

  button[data-tippy]:focus {
    outline: none;
  }

  I won't include this code in the stylesheet, however. Removing the button's outline will remove its accessibility, so think carefully before you implement this.
