    <div class="c-moodal__overlay" data-moodal-close></div>
    <div class="c-moodal__inner">

Minimum

<div class="c-moodal" tabindex="-1" aria-hidden="true">
  <div class="c-moodal__container">
    <div class="c-moodal__inner">
      <div class="c-moodal__body">
        <div
          class="c-moodal__content"
          role="dialog"
          aria-modal="true"
          data-moodal-container
        ></div>
      </div>
    </div>
  </div>
</div>

3. Initialize Core

new Moodal( wrapperElement: string|HTMLElement, <options>);

// Init Core
const myModal = new Moodal('.c-moodal'); // selector or HTMLElement

// Init Core with options
const myModal = new Moodal('.c-moodal', {
  noBackgroundScroll: true,
  backgroundElement: document.querySelector('.page-wrapper'),
  waitContentLoaded: true,
  stateClasses: {
    isVissible: 'is-vissible',
    isLoading: 'is-loading',
  },
});

4. Add Controller

moodal.addController(<params>)

• Example 1: Get content from DOM element in the page.

<!-- controller -->
<button type="button" data-moodal-anchor="myContent">
  Show Modal of `myContent`
</button>
<!-- template for content -->
<template id="myContent" style="display:none;">
  <p>Lorem ipsum dolor sit amet, consectetur adipisicing elit,...</p>
</template>

const modalCtrl = myModal.addController({
  controllerAttr: 'data-moodal-anchor',
  getContent: (trigger) => {
    // `trigger` is value of attribute `data-moodal-anchor`.
    const targetEl = document.getElementById(trigger);
    if (!targetEl) return;
    const content = document.createElement('div');
    content.innerHTML = targetEl.innerHTML;
    // Must return a HTMLElement
    return content;
  },
});

// You can show/hide modal by JavaScript
modalCtrl.show('myContent');
modalCtrl.hide();

• Example 2: Get content from page by fetch

<!-- controller -->
<button data-moodal-ajax="target.html">Show Modal of `target.html`</button>

const modalCtrlAjax = myModal.addController({
  controllerAttr: 'data-moodal-ajax',
  getContent: async (trigger) => {
    const response = await fetch(trigger, {
      method: 'GET',
    });
    const data = await response.text();
    const wrapper = document.createElement('div');
    wrapper.innerHTML = data;
    const content = wrapper.querySelector('article');
    if (!content) {
      throw new Error('No Content!');
    }
    return content;
  },
});

5. Styling

No theme styles is included in this library.
You need to add the theme css yourself.

.c-moodal__bg {
  background-color: rgba(0, 0, 0, 0.7);
}
.c-moodal__inner {
  padding-top: 60px;
  padding-bottom: 60px;
}
.c-moodal__body {
  border-radius: 6px;
  padding: 40px;
  background-color: #fff;
}

Controller Params

myModal.addController({

    // ...some code
    return content; // return HTMLElement
  },
  controllerAttr: 'data-modal-control',
});

Lifecycle Hooks

myModal.addController({
    getContent: (target)=> {
        ...
    },
    beforeAppend: (context) => {
        // context argment is object  { content: HTMLElement, trigger:string }
        console.log('on before append:',context);
    },
    afterAppend: ({content,trigger}) => {
        // if this return `Promise`, proccess wait for resolve.
       return new Promise((resolve, rejects) => {
           console.log('content:',content,'trigger:',trigger);
            setTimeout(() => {
                console.log('1000ms later after appending');
                resolve();
            }, 1000);
        });
