The correct answer is B) A brief moment where a page is rendered with browser default styles before the author's CSS finishes loading and applying, often caused by render-blocking CSS loaded late, @import chains, or certain font-loading strategies
B
Correct Answer
A brief moment where a page is rendered with browser default styles before the author's CSS finishes loading and applying, often caused by render-blocking CSS loaded late, @import chains, or certain font-loading strategies
Explanation
FOUC occurs when the browser renders content before stylesheets are applied, briefly showing unstyled (default) content; placing CSS links early in <head> and avoiding render-blocking delays helps prevent it.
