Answer 1

You can use get_the_post_thumbnail_url() to get post thumbnail url.

<div class="col-lg-3 col-md-3 col-sm-6 col-xs-12">
        <div class="single_service_item">
            <div class="service_icon transition3s">
                <div class="icon_border">
                    <span style="background-image: url('<?php echo get_the_post_thumbnail_url(get_the_ID(), 'full'); ?>');"></span>
                </div>
            </div>
            <div class="service_text">
                <h5><?php the_title(); ?></h5>
                <p><?php the_content(); ?></p>
            </div>
        </div>
    </div>
