What you're building
Type a <button> element directly into the code editor. Give it your own text. Then style it in CSS so it feels clickable — padding, rounded corners, maybe a colour that matches your page.
How the editor knows you're done
The code contains the string <button anywhere. That's it. Styling is optional, but the experience is much better if you try.
A starting point
Drop this into the HTML panel:
<button class="my-btn">Click me!</button>And this into the CSS panel:
.my-btn {
padding: 10px 20px;
border-radius: 8px;
background: #2563eb;
color: white;
border: none;
cursor: pointer;
}Then change the text, the colour, the padding — make it yours.
