Katsushi Kawamori

<ul>
<li>Enter page breaks and before/after descriptions. Values are used in pagination.</li>
<li>Do not mix this block with the Page Break block, as it may cause the comment to be misaligned.</li>
</ul>
<h4>How it works</h4>
<span class="embed-youtube" style="text-align:center; display: block;"><iframe loading="lazy" class="youtube-player" width="750" height="422" src="https://www.youtube.com/embed/4WNGiGnnjbc?version=3&rel=1&showsearch=0&showinfo=1&iv_load_policy=1&fs=1&hl=en-US&autohide=2&wmode=transparent" allowfullscreen="true" style="border:0;" sandbox="allow-scripts allow-same-origin allow-popups allow-presentation allow-popups-to-escape-sandbox"></iframe></span>
<h4>Filter hooks</h4>
<pre><code>/** ==================================================
 * Filter for CSS URL.
 * Default CSS -> /pagebreak-description/css/style.css
 */
add_filter(
    'pagebreak_description_css', 
    function() {

        /* If you put mydesign.css in wp-content/uploads */
        $wp_uploads = wp_upload_dir();
        $upload_url = $wp_uploads['baseurl'];
        if ( is_ssl() ) {
            $upload_url = str_replace( 'http:', 'https:', $upload_url );
        }
        $upload_url = untrailingslashit( $upload_url );
        $url = $upload_url . '/mydesign.css';

        return $url;
    },
    10,
    1
);
