This snippet of code showcases a unique two-column layout, utilizing both bootstrap and flexbox. The left column is dedicated to displaying video descriptions, while the right column houses the embedded video.
<div class="d-flex flex-row flex-wrap">
<div class="col-md-5 col-12 pe-md-2 order-md-first order-last">
placeholder
</div>
<div class="col-md-7 col-12 ps-md-2 ratio ratio-16x9">
<iframe width="100%" src="https://www.youtube.com/embed/WUgvvPRH7Oc?controls=0" frameborder="0" allowfullscreen></iframe>
</div>
</div>
