Simple tooltips made of pure CSS

Balloon.css lets you add tooltips to elements without JavaScript and in just a few lines of CSS.

Demo & Playground

You can play with Balloon.css here: https://jsfiddle.net/9fboea3u/

You also can check more examples at the website: http://kazzkiq.github.io/balloon.css/

Usage

Installation

Using npm:

npm install balloon-css

CDN version (provided by cdnjs):

<link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/balloon-css/0.5.0/balloon.min.css">

Manually: Simply download balloon.min.css from this repo and add it to your HTML. e.g.

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

Positioning

For positioning, use data-balloon-pos attribute with one of the values: up, down, left, right, up-left, up-right, down-left or down-right:

<button data-balloon="Whats up!" data-balloon-pos="up">Hover me!</button>
<button data-balloon="Whats up!" data-balloon-pos="left">Hover me!</button>
<button data-balloon="Whats up!" data-balloon-pos="right">Hover me!</button>
<button data-balloon="Whats up!" data-balloon-pos="down">Hover me!</button>

<button data-balloon="Whats up!" data-balloon-pos="up-left">Hover me!</button>
<button data-balloon="Whats up!" data-balloon-pos="up-right">Hover me!</button>
<button data-balloon="Whats up!" data-balloon-pos="down-left">Hover me!</button>
<button data-balloon="Whats up!" data-balloon-pos="down-right">Hover me!</button>

Showing tooltips programatically

If you want to show tooltips even when user interaction isn't happening, you can simply use the data-balloon-visible attribute:

<button data-balloon="Whats up!" data-balloon-pos="up" id="show-tip">Hover me!</button>
<script>
  const btn = document.getElementById('show-tip')
  btn.setAttribute('data-balloon-visible', '')
</script>

Glyphs and Icon Fonts

You can also add any HTML special character to your tooltips, or even use third-party Icon fonts:

<button data-balloon="HTML special characters: &#9787; &#9986; &#9820;" data-balloon-pos="up">Hover me!</button>
<button data-balloon="Emojis: 😀 😬 😁 😂 😃 😄 😅 😆" data-balloon-pos="up">Hover me!</button>

Example using Font Awesome:

<button class="fa" data-balloon="Font Awesome: &#xf030; &#xf133; &#xf1fc; &#xf03e; &#xf1f8;" data-balloon-pos="up">Hover me!</button>

Contributing

Balloon.css is mantained in SASS and LESS. To contribute with bugfixes and enchancements you must follow this steps:

Clone repo. E.g. git clone https://github.com/kazzkiq/balloon.css.git
Run npm install
Edit SASS/LESS files and run npm run build-all to generate the production CSS files. (alternatively you can run build-sass or build-less for specific compiling).
Make sure to test the production files over the website (branch gh-pages) before submitting a Pull Request.

Note 1: Remember to update both SASS and LESS files after your changes (both must always be in sync).

Note 2: You're not obligated to use the built-in tasks from the above steps. If you're using your own build, just make sure to update production and source files before submitting a PR.
