Gecko

Gecko is a web rendering engine developed by Mozilla, responsible for displaying web pages in browsers like Firefox. It interprets HTML, CSS, and JavaScript to turn code into the visual content you see online. Gecko ensures web pages look consistent across different platforms and devices by following web standards. It also manages secure browsing features and supports emerging web technologies. Essentially, Gecko serves as the core software that translates web code into the interactive, graphical experience users expect when browsing the internet.
