Code of conduct

CSS Day is an informal though professional, inclusive event that respects all individuals regardless of gender, sexual orientation, age, disability, ethnicity, or religion or lack thereof. So please don’t be nasty or mean to yourself or others. Be nice. Be considerate. Be civil. It’s easy.

“‘First of all, we have a CoC’. Nice way to start a conf” — We expect high standards from our speakers and attendees, on various levels

If you are being harassed, notice that someone else is being harassed, or have any other concerns, please contact a member of the event staff at the registration desk or wherever else you spot them. If you cannot immediately find any event staff, please find a member of the venue staff and ask them to get in touch with us quickly. If you can't or prefer not to immediately notify a person, you can always contact us via the other options noted above.

If you want clarification of this code of conduct (adapted from the An Event Apart code of conduct), please contact us in any way you prefer.
