CSS Horizontal Navigation Bar (Dropdown Menu)

We will use CSS styles to create a Horizontal Navigation Bar with Dropdown Menu.

Horizontal Menu (With Dropdown)

This example uses HTML <div> element to create a Dropdown Menu.

The <div> element is added to the <li> item in the <ul> element.

The <div> element is hidden by default with display:none;.

When the mouse gets over the <li> item, the Dropdown menu gets visible, with display:block;.
