We do a special type of refreshing of your demo when you are just making CSS changes. It’s called CSS injection. Rather than refreshing the entire page with your changes, we just kinda rip out the old CSS and put in the new CSS. Not only is it faster, it can be mighty convenient when […]

We just made a few changes to how the Details View and Comments Popup (inside the Editor) look on Pens. Details View We’ve moved your Pen’s stats up in line with your avatar and follow button. This means we had more room to show you all your Pen’s lovers by default! If you’re really clever, […]
