displaying a hint box when input field is in focus

Hi,

I found some code (html and javascript) on the internet which displays a hint box alongside an input field when it is in focus. When I put the code in a normal html page it works but when I incorporates it into wordpress it doesn’t. There is no error but the hint box just doesn’t appear. Can someone tell me if anything else is needed in the wordpress environment? Thanks!

I put the css and javascript in the header.php and the html in the template file. The html in the template file is as follows:

<?php get_header(); ?>

<?php
  echo '<dl>';
  echo '<dt>';
  echo '<label for="firstname">First Name:</label>';
  echo '</dt>';
  echo '<dd>';
  echo '<input name="firstname" id="firstname" type="text" />';
  echo '<span class="hint">Name in French<span class="hint-pointer">&nbsp;</span></span>';
  echo '</dd>';
  echo '</dl>';
?>

<?php get_footer(); ?>

Here is the long css and javascript code in the header.php

<style type="text/css">

/* All form elements are within the definition list for this example */
dl {
	font:normal 12px/15px Arial;
    position: relative;
    width: 350px;
}
dt {
    clear: both;
    float:left;
    width: 130px;
    padding: 4px 0 2px 0;
    text-align: left;
}
dd {
    float: left;
    width: 200px;
    margin: 0 0 8px 0;
    padding-left: 6px;
}

/* The hint to Hide and Show */
.hint {
   	display: none;
    position: absolute;
    right: -250px;
    width: 200px;
    margin-top: -4px;
    border: 1px solid #c93;
    padding: 10px 12px;
    /* to fix IE6, I can't just declare a background-color,
    I must do a bg image, too!  So I'm duplicating the pointer.gif
    image, and positioning it so that it doesn't show up
    within the box */
    background: #ffc url(pointer.gif) no-repeat -10px 5px;
}

/* The pointer image is hadded by using another span */
.hint .hint-pointer {
    position: absolute;
    left: -10px;
    top: 5px;
    width: 10px;
    height: 19px;
    background: url(pointer.gif) left top no-repeat;
}
labelx {
float: left;
width: 19em;
margin-right: 0em;
padding-right:5em;
text-align: right;
}
</style>
