See The Posts and Collections You’ve Hearted

You’ve been able to heart Posts and Collections for a little while now, but it was just kind of a gesture as not much was being done with that heart. Our bad – but that’s been our development style – don’t hold up releasing a feature just because you could make it better later. Now […]

Awwwards Conference

The Awwwards conference is coming up this February 24-25 in Barcelona, Spain. If you’re a code artist, you can win 2 tickets to the conference (hotel included).

Flexy Flexy Editors!

The code editors are manually resizeable now! Plus you can collapse them all the way down, maximizing space for the others! Pretty cool eh? It took us a while to get here because this kind of thing is actually pretty tough! I blogged about all the design decisions behind it over on my personal CodePen […]

Adjusting CodeMirror Settings In The Editor

The idea is that we grow as a business as more people sign up. As we create new and valuable features, more people will sign up! […]

Comment Spam Checking via Akismet

In the last few months we’ve had a couple of comment spammers come through so we decided to do the work needed to fight it. Email verification should catch a bunch of them, but we’re doing even more now. We’re now running all comments (for Pens and Posts) through Akismet, the spam-checking service from Automattic. […]

AniJS

Dariel Noel has created a neat little JavaScript library for interface animations. It’s not the animations themselves that are interesting, it’s the syntax of how you apply them.
