Create a dropdown menu that appears when the user moves the mouse over an element.
Step 1) Add HTML:
Example
<button>Dropdown</button>
<div>
<a href="#">Link 1</a>
<a href="#">Link 2</a>
<a href="#">Link 3</a>
</div>
</div>
Example Explained
Use any element to open the dropdown menu, e.g. a <button>, <a> or <p> element.
Use a container element (like <div>) to create the dropdown menu and add the dropdown links inside it.
Wrap a <div> element around the button and the <div> to position the dropdown menu correctly with CSS.
Step 2) Add CSS:
Example
.dropbtn {
background-color: #04AA6D;
color: white;
padding: 16px;
font-size: 16px;
border: none;
}
/* 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: #f1f1f1;
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: #ddd;}
/* 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;}
Example Explained
We have styled the dropdown button with a background-color, padding, etc.
The.dropdown class usesposition:relative, which is needed when we want the dropdown content to be placed right below the dropdown button (usingposition:absolute).
The.dropdown-content class holds the actual dropdown menu. It is hidden by default, and will be displayed on hover (see below). Note themin-width is set to 160px. Feel free to change this.Tip: If you want the width of the dropdown content to be as wide as the dropdown button, set thewidth to 100% (andoverflow:auto to enable scroll on small screens).
Instead of using a border, we have used thebox-shadow property to make the dropdown menu look like a "card". We also use z-index to place the dropdown in front of other elements.
The:hover selector is used to show the dropdown menu when the user moves the mouse over the dropdown button.
