Div doesn't appear on hover - html

Question

the div doesn't appear when I hover on a button, but I've used the specified code in w3schools.com. What's wrong?
Here's my code:
html {

As I've said before, this dropdown is made as said in the w3schools.com site.

Answer 1

If you adjust your HTML to place the hidden dropdown directly after the nav item you want it to interact with, then you can add the CSS rule:
/* show the dropdown when hovering on the nav item */
.navbar a:hover + .dropdown,
/* show the dropdown when hovering on the hidden items */
.dropdown:hover {
display: initial;
}
to display the hidden dropdown when you hover over the nav item.
Note that this currently doesn't have keyboard/accessibility support, this is just a slightly modified version of the code you're currently working with that does work correctly with a mouse.
