From devs: JS code changes cause the page to flicker: If visitors use only the operations supported by the visual editor, ABT should know the exact elements modified and hide them until a variation change is loaded. But if you add a JavaScript code snippet to change some elements on the web page, you might notice a flicker-original content will flash before the change is applied—on the live site. To minimize the

flicker, add a code snippet to your editor to allow ABT to keep the body hidden while the changes are being applied.

Example from a previous testing platform: vwo_$("body").vwoCss({"visibility":"visible !important"});
