In this article, we will see how can we create a contact form with the help of HTML, CSS, and JavaScript. In a contact form there are basically two sections one is the input fields and the other is the submit button section.

PrerequisitesApproach- Create a HTML structure for the contact form component having proper id and classes for the styles.
- Add a CSS file which contains all the styles related to the contact form component.
- Add a JavaScript file having all the logic for validation and boundary checks.
- Form Validations Conditions
- Length of name should be 5 or more.
- Length of subject should be 10 or more.
- Length of number should be 10.
- Email must include @ and length more than 6.
- Message length must be 40 characters.
Then, link the JavaScript and CSS file to the HTML file.
