Edit the pad on the right to build your HTML page (click the Create Pad button if necessary). Here's a simple page you can copy-and-paste into the pad to get started:

<!DOCTYPE html>
<meta charset="utf-8">
<title>My First Web Page</title>
<p>Here is my first Web page!</p>

Once you've written something, you can view your page at htmlpad.org/oh-newsletter-201501/.

Saving happens automatically, so don't worry about that.

Keep switching back and forth between the editor and the view to rapidly iterate on your design. Give the editor link to a friend if you'd like to collaborate in real-time!
