Required
The HTML required attribute specifies that filling out an input field is mandatory before a form can be submitted.
If the user does not fill in the input field, the form will not submit and it will give a message asking the user to fill out the field.
The required attribute is applicable to <input>, <select>, and <textarea>.
<input> example:
<!DOCTYPE html>
<html>
