This example is from a site that has nine categories going across the top. Blog post grid has drop shadow so I put drop shadow in for these as well.

CSS

<style>

.blog-header-shadow { 
	margin-top: 30px;
		margin-bottom: 30px;
	   box-shadow: 0 4px 8px 0 rgba(0, 0, 0, 0.2), 0 6px 20px 0 rgba(0, 0, 0, 0.19);
	   min-height: 225px;
}
.blog-header-title {
	padding-left: 5px;
		padding-right: 5px;
	font-weight: bold; 
	margin-top: 15px;
}
.blog-header-img { 
	max-width: 150px; 
}
</style>

HTML

I used u-grids-9 here because we have 9 elements and without u-grids-9 they drop into two rows. Auto grids are great ways to force odd number of grids into one row.

<div class="o-layout u-hidden u-shown--s u-grids-9" style="display: flex !important;">
<div class="o-layout__item u-text-center">
	<div class="blog-header-shadow">
	<a href=/some-link.html" title="some title">
		   <img class="blog-header-img" loading="lazy" src="/some-image.jpg" alt="some alt text" title="some title">
		   <div class="blog-header-title">some title</div>
	</a>
	</div>
</div>
