# ♎️ Libra.js
A lightweight, focused, vanilla JavaScript image lightbox library, only around ✨**3KB** after minified.
_*GIF might appear slower than actual._
## Usage
Grab [libra.min.js](https://github.com/BigCoke233/libra/blob/master/dist/libra.min.js) and put it in your project.
Then import it as a module:
```html
<script type="module">
import LightBox from '/dist/libra.min.js';
new LightBox();
</script>
```
Make sure your images all have their `data-libra` attribute, or any other selector you may specify in configuration.
```html
<div class="libra">
<img data-libra src="1.jpg" />
<img data-libra src="2.jpg" />
<!-- ... -->
</div>
```
Also, include [libra.css](https://github.com/BigCoke233/libra/blob/master/src/libra.css).
```html
<link rel="stylesheet" href="/src/libra.css" />
```
## Configuration
You can configure Libra.js by passing an object to the constructor. The defaults are:
```js
new LightBox({
selector: '[data-libra]', // Selector for images to be lightboxed
margin: 50, // Margin around the lightbox
offset: { x: 0, y: 0 } // Offset for the lightbox position
});
```
## Development
```
npm install
npm run build
```
## Philosophy
### Why I made Libra.js
I've been using [Fancybox](https://fancyapps.com/fancybox/) on my blog for a long time. While it is an excellent library, it also includes lots of features I don't need, which can slow down performance and increase the bundle size. After searching available alternatives, I found most of them either not well maintained or just as heavy. So I developed Libra.js for my own use, and I hope you find it useful, too!
### Things I won't do with Libra.js
- I won't support IE or older browsers. Please use a modern browser and make sure it's up to date.
- I won't add too many features or configurations for customization. You just click on an image and see the zoomed-in and centered version. That's all.
### Why it's called Libra.js
It's a light-box plugin that focuses on simplicity, so I called it "libo" at first, which is a combination of the first 2 letters of "light" and "box". Then I realized that "libo" sounds a lot like "libra", which is a zodiac sign. I decided to keep the name "libra" because it's a more recognizable and memorable name.
