```

## Documentation

A full documentation is available [here](https://popup-js.rtfd.io).

## Usage/Examples

Create a popup by instantiating the Popup class with customization parameters.

```javascript
const myPopup = new Popup({
    id: "my-popup",
    title: "My First Popup",
    content: `
        An example popup.

});
```

Display the popup by calling the `.show()` method.

```javascript
myPopup.show();
```

Examples of a more complex popup:

```javascript
