Customize “the_posts_pagination” and put list instead div

Hello everybody, I need help with my custom wordpress pagination.

I’m looking to get this :

This is what I did :

in the functions.php, I’ve add this code :

function wp_custom_pagination($args = [], $class="pagination") {
    if ($GLOBALS['wp_query']->max_num_pages <= 1) return;

    $args = wp_parse_args( $args, [
            'mid_size'                   => 2,
            'prev_next'                  => false,
            'prev_text'                  => __('Older posts', 'textdomain'),
            'next_text'                  => __('Newer posts', 'textdomain'),
            'screen_reader_text' => __('Posts navigation', 'textdomain'),
    ]);

    $links       = paginate_links($args);
    $next_link = get_previous_posts_link($args['next_text']);
    $prev_link = get_next_posts_link($args['prev_text']);
    $template    = apply_filters( 'navigation_markup_template', '
    <div class="col-auto">
        <a href="" class="btn btn-outline-white text-dark">%3$s</a>
    </div>
    <div class="col-auto">
        <nav class="navigation %1$s" role="navigation">
                <h2 class="screen-reader-text">%2$s</h2>
                <ul class="nav-links pagination mb-0 text-dark">
                    <li class="page-item">%4$s</li>
                </ul>
        </nav>
    </div>
    <div class="col-auto">
        <a href="" class="btn btn-outline-white text-dark">%5$s</a>
    </div>', $args, $class);

    echo sprintf($template, $class, $args['screen_reader_text'], $prev_link, $links, $next_link);}

After, I’ve add this code in my home.php

<?php wp_custom_pagination(); ?>

But, the result is really not what I want!

Here is the html structure code that I would need for this wp_custom_pagination :

            <div class="row justify-content-between align-items-center">
              <div class="col-auto">
                <a href="#" class="btn btn-outline-white text-dark">Previous</a>
              </div>
              <div class="col-auto">
                <nav>
                  <ul class="pagination mb-0 text-dark">
                    <li class="page-item active"><a class="page-link" href="#">1</a></li>
                    <li class="page-item"><a class="page-link" href="#">2</a></li>
                    <li class="page-item"><a class="page-link" href="#">3</a></li>
                  </ul>
                </nav>
              </div>
              <div class="col-auto">
                <a href="#" class="btn btn-outline-white text-dark">Next</a>
              </div>
            </div>

If anyone could help me and tell me and show me my mistakes and how to get what I want please.

Thanks a lot

At this time, this is the result that I obtain :

This is the generated code of my custom pagination page :

<div class="row justify-content-between align-items-center">
    <div class="col-auto">
        <a href="" class="btn btn-outline-white text-dark"></a>
        <a href="http://192.168.1.87/wordpress/blog/page/2">Older posts</a>
    </div>
    <div class="col-auto">
        <nav class="navigation pagination" role="navigation">
            <h2 class="screen-reader-text">Posts navigation</h2>
            <ul class="nav-links pagination mb-0 text-dark">
                <li class="page-item">
                    <span aria-current="page" class="page-numbers current">1</span>
                    <a class="page-numbers" href="http://192.168.1.87/wordpress/blog/page/2">2</a>
                </li>
            </ul>
        </nav>
    </div>
    <div class="col-auto">
        <a href="" class="btn btn-outline-white text-dark"></a>
    </div>
</div>

So, if you give a look at the result :

1 – You will see that the first link (Older post = %3$s) need to be enclosed with the good css class!

2 – And you’ll see that the “1, 2, 3” links need to be inside each one “li” not inside one “li”

Making your Custom Pagination design In Demo According Your Need .

below function Replace Your Function:

function wp_custom_pagination($args = [], $class="pagination") {

if ($GLOBALS['wp_query']->max_num_pages <= 1) return;

$args = wp_parse_args( $args, [
        'mid_size'                   => 2,
        'prev_next'                  => false,
        'prev_text'                  => __('Previous', 'textdomain'),
        'next_text'                  => __('Next', 'textdomain'),
        'screen_reader_text' => __('Posts navigation', 'textdomain'),
]);

$links       = paginate_links($args);
$next_link = get_previous_posts_link($args['next_text']);
$prev_link = get_next_posts_link($args['prev_text']);
$check_prev = (!empty($prev_link))?$prev_link:'Previous';
$check_next = (!empty($next_link))?$next_link:'Next';
$template    = apply_filters( 'navigation_markup_template', '
<div class="container"><div class= "row"><div style="display: flex;justify-content: space-around; align-items: center;" class="paginatin d-flex justify-content-between align-items-center"><div class="col-auto">
    <button type="button" class="btn btn-outline-info" >%3$s</button>
</div>
<div class="col-auto">
    <nav class="navigation %1$s" role="navigation">
            <h2 class="screen-reader-text">%2$s</h2>
            <ul class="pagination mb-0 text-dark">
                <li class="page-item">%4$s</li>
            </ul>
    </nav>
</div>
<div class="col-auto">
   <button type="button" class="btn btn-outline-info">%5$s</button>
</div></div></div><div>', $args, $class);

echo sprintf($template, $class, $args['screen_reader_text'], $check_next, $links, $check_prev);

}

Add Some Css In Your Header :

function add_css_pagination(){
?>  
    <style type="text/css">
        span.page-numbers.current {
            background: #a8307c;
            color: white;
        }
        button.btn a {
            color: #f4f4f4;
            text-decoration: none;
        }
        button.btn.btn-outline-info a {
            color: darkslategrey;
            font-weight: 600;
        }
        button.btn.btn-outline-info {
            background: unset;
            border: 1px solid turquoise;
            color: darkslategrey;
            font-weight: 600;
        }
    </style>

 <?php
 }
 add_action('wp_head','add_css_pagination');
