Sometimes find it useful to embed the jss/enroll form into other pages, so thought I'd share:
<body>
<form name="login_form" method="post" action="https://JSS:8443/enroll">
<input type="text" name="username" placeholder="Username" value="">
<input type="password" name="password" placeholder="Password">
<input class="submit" type="submit" name="submit" value="Enroll">
</form>
</body>
