How to stop A/B testing flickering?

A/B testing flicker is a phenomenon where users see a sudden change in the appearance of a web page or application as a result of A/B testing. This happens when the A/B testing tool is making changes to the page or application in real time, causing the page to flicker or flash between the different versions being tested. This can be confusing and disruptive for users, and can potentially affect the accuracy of the A/B test results.

To stop A/B testing from flickering, you can include the following code in your website right before Howuku tracking code:

<!-- anti-flicker -->
<style>.abhide { opacity: 0 !important} </style>
<script>(function(h,i,d,e){
i.className+=' '+d;h.d = function(){i.className = i.className.replace(RegExp(' ?'+d),'')};
setTimeout(function() {h.d();}, e.timeout);})
(window,document.documentElement,'abhide',{ timeout: 3000 });
</script>

And, it should look like this.

<!-- anti-flicker -->
<style>.abhide { opacity: 0 !important} </style>
<script>(function(h,i,d,e){
i.className+=' '+d;h.d = function(){i.className = i.className.replace(RegExp(' ?'+d),'')};
setTimeout(function() {h.d();}, e.timeout);})
(window,document.documentElement,'abhide',{ timeout: 3000 });
</script>

<script>
(function(t,r,a,c,k){
  c=['track','identify','converted'],t.o=t._init||{},
  c.map(function(n){return t.o[n]=t.o[n]||function(){(t.o[n].q=t.o[n].q||[]).push(arguments);};}),t._init=t.o,
  k=r.createElement("script"),k.type="text/javascript",k.async=true,k.src="https://cdn.howuku.com/js/track.js",k.setAttribute("key",a),
  r.getElementsByTagName("head")[0].appendChild(k);
})(window, document, "YOUR-UNIQUE-CODE");
