Browser Tax

Definitions

1. The extra time, code, and testing effort required because browsers behave differently or impose awkward constraints. In frontend slang, browser tax is the price teams pay for shipping real software to the messy web rather than to a single ideal runtime.

   In plain English: The extra effort required to deal with browser quirks and compatibility issues.

   Example: "The feature looked done in local Chrome testing, but the browser tax arrived later in the form of Safari layout bugs and mobile input edge cases."
