Set a rounded active and hover button with CSS
The CSS :hover pseudo-class allows you to add interactive effects when users hover over elements, while the border-radius property creates rounded corners. Combining these with the .active class creates visually appealing navigation buttons with distinct states.
Syntax
/* Hover effect */
selector:hover {
property: value;
}
/* Active state */
selector.active {
property: value;
}
/* Rounded corners */
selector {
border-radius: value;
}
Example: Rounded Active and Hover Buttons
The following example creates a navigation menu with rounded buttons that have different styles for normal, active, and hover states −
<!DOCTYPE html>
<html>
<head>
<style>
.demo {
display: inline-block;
margin: 20px;
}
.demo a {
color: #333;
padding: 10px 20px;
text-decoration: none;
border-radius: 25px;
margin: 0 5px;
background-color: #f0f0f0;
border: 2px solid #ddd;
transition: all 0.3s ease;
}
.demo a.active {
background-color: #007bff;
color: white;
border-color: #007bff;
}
.demo a:hover:not(.active) {
background-color: #e9ecef;
border-color: #007bff;
color: #007bff;
}
</style>
</head>
<body>
<h2>Navigation Menu</h2>
<div class="demo">
<a href="/home">Home</a>
<a href="/about">About</a>
<a href="/services" class="active">Services</a>
<a href="/portfolio">Portfolio</a>
<a href="/contact">Contact</a>
</div>
</body>
</html>
A horizontal navigation menu with rounded buttons appears. The "Services" button is highlighted in blue (active state). When hovering over other buttons, they change to a light blue border and text color with a smooth transition effect.
