CSS Dropdowns

CSS Dropdowns

What a dropdown menu provides is a hierarchical overview of the subsections contained within the menu item that spawned it. Basically, it lists all the subsections within a section of a site when you hover your mouse cursor over it.

Dropdown Examples:

1) Dropdown Text

A dropdown box that appears when the user moves the mouse over an element.

Example:

    <!DOCTYPE html>
<html>
<head>
<style>
.dropdown {
    position: relative;
    display: inline-block;
}
.dropdown-content {
    display: none;
    position: absolute;
    background-color: #f9f9f9;
    min-width: 160px;
    box-shadow: 0px 8px 16px 0px rgba(0,0,0,0.2);
    padding: 12px 16px;
    z-index: 1;
}
.dropdown:hover .dropdown-content {
    display: block;
}
</style>
</head>
<body>
<h2>Hoverable Dropdown</h2>
<p>Move the mouse over the text below to open the dropdown content.</p>
<div class="dropdown">
 <span>Mouse over me</span>
 <div class="dropdown-content">
  <p>Hello World!</p>
 </div>
