CSS Day started out in 2013 as a single-day, laser-focused, advanced CSS conference, and we started intertwining design sessions a few years ago. Our attendees and speakers are a mix of CSS designers, developers, spec writers and browser vendors, who take pride in what they know and do. We're a conference with an informal vibe and plenty of breaks, where each person can approach one another.
