Style latest post WordPress differently - php

Question

My current blog page shows all my blog posts in a grid of 3 by 'x'. However at the top I want to display the latest blog post as some sort of a featured post and thus style it a bit different (i.e full width). I tried doing it through css with :first-child but that didn't really work well. So now I'm trying the php approach. I however have no clue how to approach this. Can anyone show me where to start? This is my current code.
<section id="blogs" class="cards-list">
<div class="container cards">
<div class="row center-xs">
<?php
if(get_post_type() == 'post') {
$currentBlog = get_the_ID();
} else {
$currentBlog = '';
}
$loopBlog = new WP_Query(array(
'post_type' => 'post',
'posts_per_page' => -1,
'post__not_in' => array($currentBlog)
));
while ( $loopBlog->have_posts() ) : $loopBlog->the_post();
$blogIntro = get_field('blog_intro');
$blogImage = get_field('blog_image');
$blogImageUrl = $blogImage['sizes']['large'];
?>
<div class="col col-xs-12 col-md-4">
<a href="<?php the_permalink(); ?>" title="<?php the_title(); ?>" class="card card-event">
<figure style="<?php if($blogImageUrl != '') { echo "background-image:url('".$blogImageUrl."');"; } ?>"></figure>
<div class="content">
<span class="tag"><?php the_time('M d Y'); ?></span>
<div class="link"><h3><span><?php the_title(); ?></span></h3></div>
</div>
</a>
</div>
<?php
endwhile; wp_reset_query();
?>
</div>
</div>

You should be able to use current_post inside the loop and output different markup for the first post:
while ( $loopBlog->have_posts() ) : $loopBlog->the_post();
$blogIntro = get_field('blog_intro');
$blogImage = get_field('blog_image');
$blogImageUrl = $blogImage['sizes']['large'];
?>
<?php if ($loopBlog->current_post == 0): ?>
<!-- Output some other markup for the first post here -->
<div class="container-fluid">
</div>
<?php else: ?>
<div class="col col-xs-12 col-md-4">
<a href="<?php the_permalink(); ?>" title="<?php the_title(); ?>" class="card card-event">
<figure style="<?php if($blogImageUrl != '') { echo "background-image:url('".$blogImageUrl."');"; } ?>"></figure>
<div class="content">
<span class="tag"><?php the_time('M d Y'); ?></span>
<div class="link"><h3><span><?php the_title(); ?></span></h3></div>
</div>
</a>
</div>
<?php endif; ?>
<?php endwhile; wp_reset_query(); ?>
