Heads up! This blog post hasn't been updated in over 2 years. CodePen is an ever changing place, so if this post references features, you're probably better off checking the docs. Get in touch with support if you have further questions.

This week Ana Tudor will be your guest picker! Perhaps you know Ana from here mathematical artistic explorations like three-dimensional CSS polyhedra or her deep dive into the UI styling of range input sliders.

Ana is one of our earliest users. She’s been constantly building incredible demos for years. She used every nook and cranny feature of CodePen and has been amazing at helping us figure out bugs. She’s also great at finding and sharing other people’s interesting work, which makes her perfect for this gig.

Please welcome her as she does all the Picked Pens this week!
