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.
To our Design Patterns page, we just added: Accordions, Menu Icons, Grids, Star Ratings, Breadcrumbs, Progress Bars, Toggles, and Sliders to the already robust collection of patterns. Pretty big family now! Useful for when you're needing to look around quick for examples of common website-buildin' components.
Feel free to let us know of another good Pen that you think should be in one of these Collections.
