  <p>The modal structure is very simple:</p>
  <ul>
    <li>
      <code>modal</code>: the main container
      <ul>
        <li><code>modal-background</code>: a transparent overlay that can act as a click target to close the modal</li>
        <li>
          <code>modal-content</code>: a horizontally and vertically centered container, with a maximum width of 640px,
          in which you can include <em>any</em> content
        </li>
        <li><code>modal-close</code>: a simple cross located in the top right corner</li>
      </ul>
    </li>
  </ul>
  <p>
    <button class="button is-primary is-large modal-button js-modal-trigger" data-target="modal" aria-haspopup="true">
      Launch example modal
    </button>
  </p>
</div>

{% highlight html -%}
{{- modal -}}
{%- endhighlight %}

<div class="content">
  <p>
    To <strong>activate</strong> the modal, just add the <code>is-active</code> modifier on the
    <code>.modal</code> container. You may also want to add <code>is-clipped</code> modifier to a containing element
    (usually <code>html</code>) to stop scroll overflow.
  </p>

    Because a modal can contain <strong>anything you want</strong>, you can very simply use it to build an image gallery
    for example:

    use the <code>modal-card</code>.

    <button
      class="button is-primary is-large modal-button js-modal-trigger"
      data-target="modal-ter"

<div class="content">
  <p>
    The Bulma package <strong>does not come with any JavaScript</strong>. Here is however an implementation example,
    which sets the <code>click</code> handlers for custom elements, in vanilla JavaScript.
  </p>

  <p>There are 3 parts to this implementation:</p>

  <ul>
    <li>add the HTML for the <strong>modal</strong> (this modal is hidden by default)</li>
    <li>
      add the HTML for a button to <strong>trigger</strong> the modal (you can style this button however you want)
    </li>
    <li>
      add the JS code to add the <code>click</code> event on the <strong>trigger</strong> to open the
      <strong>modal</strong>
    </li>
  </ul>
</div>

<div class="content">
  <h4>1. Add the HTML for the modal</h4>

  <p>At the end of your page, before the closing <code>&lt;/body&gt;</code> tag, at the following HTML snippet:</p>
</div>

{% highlight html -%}
{{- modal_js_html -}}
{%- endhighlight %}

<div class="content">
  <p>The <code>id</code> attribute's value must be <strong>unique</strong>.</p>
</div>

<div class="content">
  <h4>2. Add the HTML for the trigger</h4>

  <p>Somewhere on your page, add the following HTML button:</p>
</div>

<div class="block">
  {{ modal_js_trigger }}
</div>

{% highlight html -%}
{{- modal_js_trigger -}}
{%- endhighlight %}

<div class="content">
  <p>
    You can style it however you want, as long as it has the <code>js-modal-trigger</code> CSS class and the appropriate
    <code>data-target</code> value. For example, you can add the <code>button is-primary</code> Bulma classes:
  </p>
</div>

<div class="block">
  {{ modal_js_trigger_bulma }}
</div>

<div class="content">
  <h4>3. Add the JS for the trigger</h4>

  <p>In a <code>script</code> element (or in a separate <code>.js</code> file), add the following JS code:</p>
</div>

{% highlight javascript -%}
{{- modal_js_code -}}
{%- endhighlight %}

<div class="content">
  <p>
    As long as you can toggle the <code>is-active</code> modifier class on the <code>modal</code> element, you can
    choose how you want to implement it.
  </p>
</div>



<script type="text/javascript">
  {
    {
      modal_js_code;
    }
  }
