How can I validate form inputs using CSS?

You can use CSS to style invalid inputs by utilizing the :invalid pseudo-class. For example, you can change the border color of an input when it's invalid.

Can you show me an example of that?

Sure! Here's a simple example:

input:invalid {
    border: 2px solid red;
}

This will make the border red for any invalid input.

What about showing a message when the input is invalid?

CSS alone can't display messages, but you can use HTML5 attributes like title or aria-describedby to provide feedback.

Is there a way to combine CSS with JavaScript for better validation?

Absolutely! You can use JavaScript to check the input value and then apply CSS classes based on the validation result.
