Example

element.

Use a container element (like ) to create the dropdown menu and add the dropdown links inside it.

Wrap a element around the button and the to position the dropdown menu correctly with CSS.

Step 2) Add CSS:

Example

/* Navbar container */
.navbar overflow: hidden;
background-color: #333;
font-family: Arial;
>

/* Links inside the navbar */
.navbar a float: left;
font-size: 16px;
color: white;
text-align: center;
padding: 14px 16px;
text-decoration: none;
>

/* The dropdown container */
.dropdown float: left;
overflow: hidden;
>

/* Dropdown button */
.dropdown .dropbtn font-size: 16px;
border: none;
outline: none;
color: white;
padding: 14px 16px;
background-color: inherit;
font-family: inherit; /* Important for vertical align on mobile phones */
margin: 0; /* Important for vertical align on mobile phones */
>

/* Add a red background color to navbar links on hover */
.navbar a:hover, .dropdown:hover .dropbtn background-color: red;
>

/* 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 float: none;
color: black;
padding: 12px 16px;
text-decoration: none;
display: block;
text-align: left;
>

/* Add a grey background color to dropdown links on hover */
.dropdown-content a:hover background-color: #ddd;
>

/* Show the dropdown menu on hover */
.dropdown:hover .dropdown-content display: block;
>

Example Explained

We have styled the navigation bar and the navbar links with a background-color, padding, etc.

We have styled the dropdown button with a background-color, padding, etc.

The .dropdown class is the container for .dropdown-content . Since this is a element, and not an element, we have to float it to make sure that it stays next to the links.

The .dropdown-content class holds the actual dropdown menu. It is hidden by default, and will be displayed on hover (see below). Note the min-width is set to 160px. Feel free to change this.

Instead of using a border, we have used the box-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.

Example Explained

We have styled the dropdown button with a background-color, padding, etc.

The .dropdown class uses position:relative , which is needed when we want the dropdown content to be placed right below the dropdown button (using position:absolute ).

The .dropdown-content class holds the actual dropdown menu. It is hidden by default, and will be displayed on hover (see below). Note the min-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 the width to 100% (and overflow:auto to enable scroll on small screens).

Instead of using a border, we have used the box-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.
