why doesn't this simple html code work? (pattern)

could somebody tell me why this simple code doesn't work? I type a random email address with .com at the end and I receive an error that this address doesn't have the right format.

<!DOCTYPE html>

<form action="demo_form.asp">
  E-mail: <input type="email" name="email" pattern="\.com$">
  <input type="submit">



Maybe it works

<form action="demo_form.asp">
E-mail: <input type="email" name="email" pattern="+\.com$">
<input type="submit">

Try this pattern. It will validate only .com emails.


There's a problem with your pattern, try using this instead pattern="[a-z0-9._%+-]+@[a-z0-9.-]+\.[a-z]{2,3}$"
