Interactive classes in CSS provide you the ability to handle specific events that occur on HTML elements without needing to add specific classes to your HTML code. These tools are incredibly valuable for web developers because they minimize dependency on HTML code while enhancing usability and functionality.
Interactive classes include :hover, :focus, :active, and :visited. The :hover class is used when a user hovers over an element. This class is typically used for buttons and links to create beautiful visual effects.
The :focus class is widely used for interacting with form elements. With this class, you can highlight fields that the user is currently interacting with.
The content typically includes descriptions demonstrating how you can utilize these classes in real-world projects. Below is a sample code that demonstrates this better.
<style>
a:hover {
color: red;
}
input:focus {
background-color: yellow;
}
button:active {
transform: scale(0.98);
}
a:visited {
color: purple;
}
</style>
a:hover: When a user moves their mouse over a link, its color changes to red.
input:focus: Whenever an input is focused, its background color will change to yellow.
button:active: When a button is clicked, a small decrease in size is applied to simulate being pressed.
a:visited: When a link has been previously visited, its color changes to purple.
