Layer elements with z-index using CSS
When elements overlap each other on a web page, the z-index-property can be used to specify which element should appear on top. The z-index property is a CSS property that sets the stack order of an element.
Elements with higher z-index values display in front of those with lower z-index values.
Syntax:
The syntax for using the z-index property is as follows:
selector {
z-index: value;
}
The value can be any integer value, positive or negative. The default value for z-index is 0.
Usage Examples:
Here are some examples of how to use z-index in HTML with CSS:
1. Set an image on top of another element:
HTML:
<pre>
<div class="container">
<img src="image.jpg" alt="Image" />
<div class="content">
<h1>Title</h1>
Content
</div>
</div>
CSS:
.container {
position: relative;
}
img {
position: absolute;
z-index: 1;
}
.content {
position: relative;
z-index: 2;
}
2. Set a dropdown menu on top of other content:
HTML:
<nav> <ul> <li style="list-style-type: none;"> <ul> <li><a href="#">Home</a></li> </ul> </li> </ul> <ul> <li style="list-style-type: none;"> <ul> <li><a href="#">About</a></li> </ul> </li> </ul> <ul> <li style="list-style-type: none;"> <ul> <li class="dropdown"><a href="#">Products</a> <ul class="dropdown-menu"> <li style="list-style-type: none;"> <ul class="dropdown-menu"> <li><a href="#">Product 1</a></li> </ul> </li> </ul> <ul class="dropdown-menu"> <li style="list-style-type: none;"> <ul class="dropdown-menu"> <li><a href="#">Product 2</a></li> </ul> </li> </ul> <ul class="dropdown-menu"> <li style="list-style-type: none;"> <ul class="dropdown-menu"> <li><a href="#">Product 3</a></li> </ul> </li> </ul> </li> </ul> </li> </ul> <ul> <li style="list-style-type: none;"> <ul> <li><a href="#">Contact</a></li> </ul> </li> </ul> </nav>
CSS:
.dropdown-menu {
position: absolute;
z-index: 1;
}
