Answer 1

FOUC stands for 'Flash of Unstyled Content' and occurs when a web page displays unstyled content due to delays in loading external stylesheets.

Step-by-step explanation:

In the context of HTML, FOUC stands for "Flash of Unstyled Content," which typically occurs when a web page suddenly displays unstyled content, such as raw text and unformatted features, before the correct style is applied. This problem is often caused by delays in loading external stylesheets, usually when the CSS is loaded asynchronously with JavaScript or if there's heavy network latency. The flash is the period during which the page's content is visible, but not styled according to the designs defined in the external stylesheets.
