    I think change your pattern to this:

    <input type="text" id="mobno" name="mobno" pattern="03[0-9]{2}-[0-9]{8}" maxlength="13" required>

    The pattern you’re using enforces a mobile number starting with "09" and followed by exactly 9 digits. However, this doesn’t match the format you want (e.g., 0300-12345678), and it doesn’t allow for the inclusion of a – after the first four digits

    You need to use this pattern instead 03[0-9]{2}-[0-9]{8}

    • 03: Specifies that the mobile number should start with "03".
    • [0-9]{2}: Matches exactly two digits after "03".
    • "-": Requires a hyphen after the first four digits.
    • [0-9]{8}: Matches exactly eight digits after the hyphen.

    And you should increase the maxlenght to 13

    <form action="action.php" method="post">
    <label for="mobno">Mobile No</label>
    <input type="text" id="mobno" name="mobno" pattern="03[0-9]{2}-[0-9]{8}" maxlength="13" required>
    <br><br>
    <input type="submit" value="Submit">
</form>
