The Escape Button is a simple floating action button that allows users to quickly and safely exit your website in case of emergency. We originally developed this tool to support survivors of sexual and domestic violence and hope it can be useful for the community as well.
The Escape Button is built to handle both situations where the user or browser does not have Javascript enabled and when it does.
It is possible to override the styling of the Escape Button in your own stylesheet.
