Flash of unstyled content
open-in-new
<p>A flash of unstyled content (FOUC, or flash of unstyled text) is an instance where a <a href="/facts/Web_page/5JK7xQLe">web page</a> appears briefly with the browser's default styles prior to loading an external <a href="/facts/CSS_stylesheet/tA90XBQo">CSS stylesheet</a>, due to the <a href="/facts/Web_browser_engine/wLna3ate">web browser engine</a> rendering the page before all information is retrieved. The page corrects itself as soon as the style rules are loaded and applied; however, the shift may be distracting. Related problems include flash of invisible text and flash of faux text. </p>
