Render-blocking
Render-blocking refers to any part of the process of loading a website that blocks the rendering of the user interface. Render-blocking is bad for web performance because it increases the length of time until users can interact with the site — for example, viewing content or interacting with controls. The most common causes of render-blocking are initially-loaded CSS or JavaScript files.
