Step 3 Edit Web Forms
Sometimes you may want to edit a web form. A web form is when you have to "submit" something to a server, usually in logins or forgotten password forms. Let's say we have a forgot password form for some website, and this is the HTML code they used:
<form action="http://www.website.com/forgotpassword.php" method="post"> <input type="hidden" name="to" value="email@example.com">
This is basically saying "Void the documents first form, skip (to) and go to the value (value) and make it equal to my email".
