How to Validate Email in HTML CSS & JavaScript?

In HTML, you can use the "email" input type to prompt the user to enter a valid email address. This will show the appropriate keyboard on mobile devices and also provide some basic validation on the client-side.

However, client-side validation alone is not enough, as it can be bypassed by malicious users or bots. Therefore, you should also perform server-side validation to ensure that the email address is valid and not fake or spam.

In CSS, you can use pseudo-classes to style the input element based on its validity. For example, you can set the border color to red if the email input is invalid.

In JavaScript, you can use regular expressions (regex) to validate the email address format. Regex is a powerful tool for matching patterns in strings, and there are many regex patterns available for validating email addresses.

When validating an email address with JavaScript, you can use the "test" method of the regex object to check if the email address matches the pattern. You can also use the "match" method to extract specific parts of the email address, such as the username and domain.

Overall, validating email addresses is an important step in ensuring the security and integrity of your web application. By using HTML, CSS, and JavaScript together, you can provide a seamless user experience while also protecting your website from spam and other malicious activity.
