In the phrase "The King is dead, long live the King", the first instance refers to the departing King, and the second instance refers to his successor.
So in this case the title doesn't really make sense, because hover hasn't been replaced by another thing called hover.
I hate this phrase. It's so overused.
Don't let logic get in the way of a great clickbait medium.com title.
It really wasn't a clickbait title, and the article was pretty good. In the article he establishes a better way to use :hover state now that so many laptops have touch screen. So, the logical equivalence would be more "The typical use for hover is dead, long live a better use for hover". It's not a brilliant title, but I read the title with some expectation for the content and the article was well reasoned and wasn't another typical "i've seen this same medium post a thousand times" type article.
Had an unreasonable panic that hover.com was dead or bought by godaddy when I read this headline.
