CSS Dropdowns
CSS-Dropdowns:
Dropdown menus in CSS are commonly used in navigation bars or forms to provide a list of options when a user interacts with a specific element (usually a button or link). Creating a basic CSS dropdown menu involves using CSS to hide and show a list of items when the user hovers over or clicks on a trigger element. Here's a step-by-step guide on how to create a simple CSS dropdown menu:
HTML Structure:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<link rel="stylesheet" href="styles.css">
<title>Dropdown Menu</title>
</head>
<body>
<div class="dropdown">
<button class="dropbtn">Dropdown</button>
<div class="dropdown-content">
<a href="#">Option 1</a>
<a href="#">Option 2</a>
<a href="#">Option 3</a>
</div>
</div>
</body>
</html>
CSS (styles.css):
<style>
/* Style the dropdown container */
.dropdown {
position: relative;
display: inline-block;
}
/* Style the dropdown button */
.dropbtn {
background-color: #4CAF50;
color: white;
padding: 10px;
border: none;
cursor: pointer;
}
/* Style the 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;
}
/* Style the dropdown links */
.dropdown-content a {
color: black;
padding: 12px 16px;
text-decoration: none;
display: block;
}
/* Change link color on hover */
.dropdown-content a:hover {
background-color: #ddd;
}
/* Show the dropdown content when hovering over the dropdown container */
.dropdown:hover .dropdown-content {
display: block;
}
</style>
In this example:
We have a simple HTML structure with a div container for the dropdown, a button as the trigger element, and a div for the dropdown content.
CSS is used to style the dropdown container, button, and dropdown content. The dropdown content is initially hidden (display: none;).
When a user hovers over the dropdown container (.dropdown:hover), we change the display property of the dropdown content to block, making it visible.
We style the links inside the dropdown content, and they change color on hover.
