CSS Dropdowns
Basic Dropdown
Create a dropdown box that appears when the user moves the mouse over an element.
See this example:
<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>
<div class="dropdown">
<span>Mouse over me</span>
<div class="dropdown-content">
<p>Hello World!</p>
</div>
</div>
Dropdown Menu
Create a dropdown menu that allows the user to choose an option from a list
This example is similar to the previous one, except that we add links inside the dropdown box and style them to fit a styled dropdown button
See this example:
<style>
/* Style The Dropdown Button */
.dropbtn {
background-color: #4CAF50;
color: white;
padding: 16px;
font-size: 16px;
border: none;
cursor: pointer;
}
/* The
container <div> - needed to position the dropdown content */
.dropdown {
position: relative;
display:
inline-block;
}
/* Dropdown Content (Hidden by Default) */
.dropdown-content {
display: none;
position:
absolute;
background-color: #f9f9f9;
min-width: 160px;
box-shadow:
0px 8px 16px 0px rgba(0,0,0,0.2);
z-index: 1;
}
/* Links inside the dropdown */
.dropdown-content a {
color: black;
padding: 12px 16px;
text-decoration: none;
display: block;
}
/* Change color of dropdown links on hover */
.dropdown-content a:hover {background-color: #f1f1f1}
/* Show the
dropdown menu on hover */
.dropdown:hover .dropdown-content {
display: block;
}
/* Change the background color of the dropdown
button when the dropdown content is shown */
.dropdown:hover .dropbtn {
background-color: #3e8e41;
}
</style>
<div class="dropdown">
<button class="dropbtn">Dropdown</button>
<div class="dropdown-content">
<a href="#">Link
1</a>
<a href="#">Link 2</a>
<a href="#">Link 3</a>
</div>
</div>
