Browser Rendering

Definitions

1. The process by which a browser parses HTML, CSS, and scripts, constructs rendering structures, computes layout, and paints visual output to the screen. Understanding browser rendering helps frontend engineers improve performance and avoid layout thrash, excessive reflow, and blocking resource patterns.

   In plain English: How a browser turns code and resources into visible page content on the screen.

   Example: "The page felt slow not because of the API but because browser rendering was blocked by a huge synchronous script in the head."
