## Demo & Playground

You can play with Balloon.css here: https://jsfiddle.net/kuzmd942/

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

## Usage

### Installation

**Using npm:**
```
npm install balloon-css
```

You can then import the CSS file directly into your JS (using Webpack, etc):

```js
// Your index.js file, etc.
import 'balloon-css';
```

or import the source file if using SASS/SCSS:

```sass
/* Your main.scss file, etc. */
@import "~balloon-css/src/balloon"
```

**CDN version:**

If you don't want to use npm, there is a CDN option:

```html
<!-- This link will always fetch the latest version of Balloon.css -->
<link rel="stylesheet" href="https://unpkg.com/balloon-css/balloon.min.css">
```

**Manually:**
Simply download [`balloon.min.css`](https://raw.githubusercontent.com/kazzkiq/balloon.css/master/balloon.min.css) from this repo and add it to your HTML. e.g.

```html
<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`:

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

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

```html
<button aria-label="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>
```

### Disabling animation

If for some reason you do not want animations in your tooltips, you can use the `data-balloon-blunt` attribute for that.

```html
<button data-balloon-blunt aria-label="No animation!" data-balloon-pos="up">No animation!</button>
```

### Customizing Tooltips

Balloon.css exposes CSS variables to make it easier to customize tooltips:

- `--balloon-border-radius`
- `--balloon-color`
- `--balloon-font-size`
- `--balloon-move`

This way, you can use custom CSS to make your own tooltip styles:

```css
/* Add this to your CSS */
.tooltip-red {
  --balloon-color: red;
}

.tooltip-big-text {
  --balloon-font-size: 20px;
}

.tooltip-slide {
  --balloon-move: 30px;
}
```

If you want to customize tooltips globally, use the `:root` selector:

```css
/* All tooltips would now be square and blue */
:root {
  --balloon-border-radius: 0;
  --balloon-color: blue;
}
```

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

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

Example using [Font Awesome](https://fortawesome.github.io/Font-Awesome/):

```html
<button class="fa" aria-label="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:

1. Clone repo. E.g. `git clone https://github.com/kazzkiq/balloon.css.git`
2. Run `npm install`
3. Edit SASS file and run `npm run build` to generate the production CSS files.
4. Make sure to test the production files over the website (branch `gh-pages`) before submitting a Pull Request.

Note 1: Remember to update **the SASS file** instead of the generated ones (`balloon.css` and `balloon.min.css` are generated on every build from SASS file).
