Gecko (Rendering Engine)

Gecko is a web rendering engine developed by Mozilla, responsible for displaying web pages in browsers like Firefox. It takes the code and content of a website—such as text, images, and styles—and interprets it to produce the visual layout you see on screen. Think of Gecko as the behind-the-scenes translator that converts web code into a readable, interactive page. It handles tasks like rendering text, images, and links, ensuring that websites appear consistent and functional across different devices and platforms. Its design emphasizes security, standards compliance, and performance, making browsing safe and reliable.
