I’m not sure how widespread this is, or if it’s a combination of elements on the page that triggers it, but since the last update to UIkit3 I’ve noticed that the transparency setting in Navbar is no longer getting applied to “Hover”.
That means, if you set the Navbar stack to transparent it will appear as such until the mouse hovers over it, then the specified colour for Hover in the settings kicks in.
The simple fix is to simply remove the transparency option and set both the regular and hover background colours to 0% opacity.
So far I’ve picked this up on two of my sites, it might be isolated to those two or more widespread. Not sure, I need to do some checking. But figured worth a post here for others who might experience the same.
