How to make dropdown in html overlap another div

css, html

Solution

You can use z-index attribute as it specifies the stack order of an element.

An element with greater stack order is always in front of an element with a lower stack order.

Note: z-index only works on positioned elements (position:absolute, position:relative, or position:fixed).

Example:

<!DOCTYPE html>
<html>
<head>
<style>
img {
    position: absolute;
    left: 0px;
    top: 0px;
    z-index: -1;
}
</style>
</head>
<body>

<h1>This is a heading</h1>

<img src="w3css.gif" width="100" height="140">

<p>Because the image has a z-index of -1, it will be placed behind the text.</p>

</body>
</html>

Problem

So I got a navigation bar and some of the items there are having a dropdown menu when you hover over them. Right below the nav bar, there is a slideshow of images. The problem is that everytime I hover on the dropdowns, The slideshow div gets in the way so the dropdown menu cant be seen. i have the ff html code ``` <div class="dropdown"> <li class="dropbtn">About Us</li> <div class="dropdown-content"> <a href="#"> Overview and History</a> <a href="#">Vision</a> <a href="#">Objectives</a> <a href="#">Organization</a> <a href="#">About NEU</a> </div> </div> ``` and the css ``` .dropbtn { background-color: inherit; color: black; padding: 12px; font-size: 20px; border: none; cursor: pointer; } .dropdown { position: relative; display: inline-block; margin: 0; padding: 0px; } .dropdown-content { display: none; position: absolute; background-color: #f9f9f9; min-width: 160px; box-shadow: 0px 8px 16px 0px rgba(0,0,0,0.2); } .dropdown-content a { color: black; padding: 12px 16px; text-decoration: none; display: block; } .dropdown-content a:hover {background-color: #f1f1f1} .dropdown:hover .dropdown-content { display: block; } .dropdown:hover .dropbtn { background-color: #0099ff; } ```
