Styling your notifications is essential for maintaining a cohesive user experience in your React application. Toastify offers several ways for you to customize the appearance of your toasts so they blend seamlessly with your app's design. You can use built-in props to adjust the look of individual toasts, or apply custom CSS classes for more advanced styling.

To start, you can use the className and bodyClassName props when displaying a toast. The className prop applies a custom CSS class to the toast container, while bodyClassName targets the body of the toast. This allows you to control margins, padding, background colors, fonts, and more. You can define your custom styles in your app's CSS file, then reference those class names in the toast props.

Another method involves using the style prop, which accepts a JavaScript object of inline styles. This is useful for making quick, one-off style changes to a specific toast.

Toastify also includes theme options that let you quickly switch between light and dark designs. The theme prop accepts values like "light", "dark", or "colored". When you set the theme prop on the Toastify container, all toasts will use that theme by default. You can also override the theme for individual toasts by passing the theme prop directly when calling the toast function.

For example, to apply a dark theme to all notifications, set theme="dark" on your Toastify container. If you want only certain toasts to use a different theme, pass theme="colored" when you show that toast.

Combining these methods, you can achieve a notification style that matches your application's branding and user interface standards.

Theme options in Toastify provide a quick way to align notifications with your application's color scheme. The main themes are "light", "dark", and "colored". The "light" theme uses a white background with dark text, which is suitable for most standard interfaces. The "dark" theme inverts those colors, making the notification blend with dark-mode layouts. The "colored" theme uses a colored background based on the notification type, such as green for success or red for error.

To apply a theme, you can set the theme prop on the Toastify container component. This will make all notifications use the selected theme by default. If you want to override the theme for a specific toast, pass the theme prop when calling the toast function. This flexibility lets you mix and match themes as needed throughout your app.

Using themes, along with custom CSS classes and inline styles, gives you full control over the appearance of your Toastify notifications.
