Wix has created 2 header tutorials / codes since I first created my tutorial. (So in total 3 different methods have been tried)
Since then, Wix made some changes to their system / code that, for whatever reason, caused different things to stop working as they did before.
Of course, sometime in between them creating their own tutorial and breaking the code, Wix released native header settings so that you can add a few types of header animation.
And yes, I have seen their solution fix, I actually reference Wix’s official post regarding the topic in my article as well.
But as you mentioned … sometimes people don’t really search for their answers … they prefer to ask and be told. So … that is why I wrote the article and blasted it out to my followers …
