I have a fixed element on my site. And there is a interaction on the menu button witch move the whole site to the left.
After that the element is no longer fixed. In the inspector in the browser its always position:fixed but it moves with the site after the interaction.
I had a look at your website, and I don’t see what the issue is?
I imagine you’re referring to the fixed navigation menu appearing at the top when scrolling down, right? What’s your expectation? For it to stay visible when you click the hamburger button?
