Answer 1

use a simple if... then... else condition and make use of your $_SESSION variable to switch those conditions. Create a new variable to hold your current style e.g. $tdStyle = "visibility: hidden;" or $tdStyle = "visibility: visible;" for hiding/showing your td, respectively.

HTML/PHP CODE: [EDIT]

<?php
  ...
  if ($_SESSION['Validation'] == "on") {
     $tdStyle = "visibility: visible;";
  } else  {
     $tdStyle = "visibility: hidden;";
  }
  ...
?>
...
<tr><td style="<?php echo $tdStyle; ?>">Wrong username or Password</td></tr>
...

EDIT: Use index.php not index.html when embedding PHP codes in HTML or your php code will be treated as plain text/html

header("Location: index.php");

NOT

header("Location: index.html");
