Email Validation in HTML CSS & JavaScript

Hey friends, today in this blog you’ll learn how to do Email Validation in HTML CSS & JavaScript. Earlier I have shared many Login Form Designs but there are no features of the Email Validation. So, it’s time to do Simple Email Validation in HTML & JavaScript.

Email Validation is a method that verifies if the user entered email address is valid or not. If an email is not valid then we can show an error message to inform the user about it.

In this small project (Email Validation in HTML), as you can in the image preview, there are two boxes with input. In the first box input, I have entered an invalid email address so there is shown a tooltip with an error message and in the second box input, I have entered a valid email address so there is shown the submit button with the green background.


You may know, the red color indicates an error and the green color indicates success. So I used these colors to inform the user about their entered email. You can also watch a demo video or tutorial of this Email Validation in HTML.

Video Tutorial of Email Validation in HTML

 
In the video, you have seen the demo of this Email Validation in HTML & JavaScript and also how I did validation using only HTML CSS & JavaScript. To validate the user-entered email address first I written a regex pattern for validation and match the user entered inputs with this pattern.

If the user entered email address is matched with the given pattern that means the user has entered a valid email else entered email is not valid. I hope you like this Email Validation in HTML CSS & JavaScript and want to get the source codes of this small project. But don’t worry I have given all codes to the bottom of this page and you can copy-paste.
