What you're building
Build a rounded, padded container with a subtle shadow. Cards are the lego piece of modern web design — once you can make one, you can make a feed, a dashboard, a portfolio.
How the editor knows you're done
The code mentions card as a class name, or uses border-radius anywhere in CSS.
A starting point
Drop this into the HTML panel:
<div class="card">
<h3>A tidy card</h3>
<p>It has padding, a border, and a shadow.</p>
</div>And this into the CSS panel:
.card {
padding: 20px;
border: 1px solid #e2e8f0;
border-radius: 12px;
box-shadow: 0 4px 12px rgba(0,0,0,0.08);
}Now duplicate the <div class="card"> a few times. Congratulations — that's a feed.
