I’m calling these pseudo‐custom events because they serve the same purpose as standard browser events: they report on certain occurrences in the UI. Here we’re using custom events to act as uniform façades to inconsistently‐implemented events. Together we’ll write some code to generate mouse:wheel events. At the end of this article, you’ll know enough to be able to write code to generate mouse:enter and mouse:leave events document‐wide.
Just in case anybody needs instructions, contact the NCAA and its Division I‐FCS, Division II and III football teams. They’ve had an actual playoff system for decades.
