3. Adding CSS Styles

Now comes the exciting part – adding CSS styles to our “alert” button. We will cover various aspects of styling, including basic styling, hover effects, focus effects, and more.

3.1. Basic Button Styling

To start, we’ll define the basic styles for the “alert” button, such as background color, text color, and padding.

3.4. Active State Styling

When the user clicks on the button, it enters the active state. We can add a darker shade to indicate the button’s activation.

3.5. Customizing Alert Icons

You can also include an alert icon to further emphasize the button’s importance. Use a font icon or an SVG image for better scalability.
