Believe it or not, it’s possible to create pure CSS alerts. So, if you want a simple and elegant solution, there are a few alert modals that you can use.
In this article, we’ll be providing some beautiful CSS alerts and some CSS styles that you can copy to create a beautiful alert, and perhaps animate it with JavaScript or just render it on the server after form submission or similar.
What Are CSS Alerts?
CSS alerts are a kind of text message that provides the visitor with certain information. They can appear as overlay notifications, dialog modals, inline, etc. CSS alerts are classified into 4 main categories:
- Danger/Error (Red)
- Warning (Yellow/orange)
- Information (Blue)
- Success (Green)
Best 28 CSS Alerts
Whether you are looking for CSS-only alerts, JavaScript-animated ones, or just some beautiful styles, check our list below:
1. Closable Pure CSS Alerts
These light-themed alerts are using only CSS.
If you pay attention, you’ll notice how they can be closed when clicking over them or on the “x” icon.
This kind of alert can come in handy when rendered server-side. For example, when submitting a form via PHP or node.
2. Beautiful & Basic CSS Only Alert
Here’s a gorgeous alert built with CSS and no javascript at all.
The examples display a basic modal once the “button” is focused.
It uses the :target pseudoelement to toggle the visibility of the popup with the alert.
3. Modal Alert Overlay In Pure CSS
This alert makes use of CSS to conditionally display a modal dialog message.
It makes use of a checkbox input and the :checked CSS property to determine when to show/hide the alert.
It’s a technique used for many CSS elements with 2 states, such as hamburger menus or CSS toggles switches.
4. Material Design Multi-color CSS Alerts
This is a great example of some beautiful and modern alert notifications.
They make use of strong and vivid colors in combination with Material Design Icons to create such a beautiful design.
5. Basic Pure CSS Alerts
If you are looking for simplicity, then these alerts are for you.
They don’t make use of any external vendor. No framework, no JS, and no icons.
Just some plain CSS to give some basic style to your alert messages.
6. Light Alerts In Pure CSS
If you are looking for some pretty alerts for your light-themed page, these are definitely for you!
I especially like the error and the success alert.
They use a minimal approach to create some beautiful styles for your alert components.
They won’t even use icons but it won’t prevent them from serving their purpose perfectly.
7. Tailwind CSS Alerts
If you use TailwindCSS as your CSS framework, then you want to make use of it to also display alerts.
This example shows how to display multiple alerts at the bottom of the page.
These alerts come with multiple colors and icons depending on the kind of alert it is: Error, success, info, or warning alert.
8. Modal Dialog Alert Message With CSS
Another CSS only solution to create a stylish alert modal.
The modals show a box with some content and a closing button.
To close the modal you can click on the dark overlay or the closing button.
This example uses the same technique as other two-state components. It uses a checkbox to track the state with CSS.
9. Timed Vanilla JS and CSS Alert
A truly modern alert that displays a notification on the top right corner of the page.
The alert times out and displays an animated progress bar to show the remaining time.
Talking about progress bars… check out these amazing CSS progress bars.
The design looks super modern and, best of all, it doesn’t use any external components! Pure CSS and Vanilla JS make the magic.

If you are looking for a big notification with some personality, these might be for you.
They don’t use any external vendor library and make use of SVG icons.
jQuery is fully optional. It only adds the closing feature, but that can be replaced if necessary for plain JS or even pure CSS.
12. Timed jQuery Text Alerts
If you are ok with using a bit of JS (or jQuery), these are some beautiful alerts.
Unlike others, these alerts get stacked underneath each other at the very top of the page.
I personally think it looks great and I like it more than the side notifications, especially for important messages or errors.
There’s a bit of jQuery involved, but you can easily turn it into Vanilla JS.

For those who are into flat design and make use of TailwindCSS, these alerts can be for you.
I personally like the selection of colors, the modern feel, and the simplicity of their design.

It’s big, it’s very original and it’s done entirely with CSS.
15. Bottom Right Tailwind + Alpine Alerts
For those who like using the latest trends and make use of TailwindCSS and Alpine.js.
Simple use of alert notifications that get displayed on the bottom right.
Each type of alert has its icon and they replace each other when clicked continuously.

The alert message accepts a title and a body, so it comes in handy for that kind of alert that requires a bit more context.

In this case, there’s no JavaScript involved and the alerts only get animated on page load.

They are made with CSS and the only external component they use is FontAwesome for the icons.
They use a white background for the alert message and add a touch of color on the icon background to define the type of alert it is.

They time out after some time and can get stacked on top of each other when triggered continuously.

For those who are still using Bootstrap 3.
These alerts will stack on top of each other with a small and cute animation.

Whether you use Tailwind CSS or not, you can take the alert styles and apply them to any other alert to step up their design.
