Div tag does not contain content

I've created a form that enters comments onto my blog posts but when the comments are displayed on the webpage the background color that I added to the div is either to big or to small. I've provided the code below. Any help is appreciated!

    <h2 id="comments-title">Comments</h2>
 <div id="comment-list">
    <?php

}
$commenttimestamp = strtotime("now");

$sql = "SELECT * FROM php_blog_comments WHERE entry='$id' ORDER BY timestamp";
$result = mysql_query ($sql) or print ("Can't select comments from table php_blog_comments.<br />" . $sql . "<br />" . mysql_error());
while($row = mysql_fetch_array($result)) {
    $timestamp = date("l F d Y", $row['timestamp']);
      printf("<div class='comment-ind'><p id='comments'><a id='username' href=\"%s\">%s</a> %s</p>", stripslashes($row['url']), stripslashes($row['name']), $timestamp);
    print("<p class='comments'>" . stripslashes($row['comment']) . "</p><div class='clr'><br></div></div>");

  }
?>

<form id="commentform" method="post" action="process.php">

<p><input type="hidden" name="entry" id="entry" value="<?php echo $id; ?>" />开发者_StackOverflow中文版

<input type="hidden" name="timestamp" id="timestamp" value="<?php echo $commenttimestamp; ?>">

<input type="text" name="name" id="name" title="Name (required)" /><br />

<input type="text" name="email" id="email" title="Mail (will not be published) (required)" /><br />

<input type="text" name="url" id="url" title="Website" value="http://" /><br />

<br />
<textarea  title="Your Comment Goes Here" name="comment" id="comment"></textarea></p>

<p><input type="submit" name="submit_comment" id="submit_comment" value="Add Comment" /></p>

</form>
</div>

CSS:

    #comments-title {
    background-color: #282828;
    width: 567px;
    height: 30px;
    font-size: 25px;
    font-family: arial;
    color: #ffffff;
    padding: 5px;
    padding-top: 6px;
    padding-bottom: 4px;
}


#comment-list{
    border:1px solid #dadada;
    width: 565px;
    padding: 5px;
    font-family: Helvetica;
    font-size: 18px;
}

#comments {
    width: 480px;
    font-size: 12px;
    color: #444444;
}

.comments {
    width: 480px;
    height: 20px;
}
.comment-ind {
    background-color: #eeeeee;
    width: 548px;
    position: relative;
    min-height: 10px;
    margin: 5px;
    padding: 8px;
}

Your problem is with height: 20px;. You can change it to min-height: 20px; and then it will be at least that height, but the way you have it, it will always be 20px tall regardless of the content.

Are we seeing the whole css that applies to this div. Looking at the screen shot I would guess that the paragraph of text is floated left and the containing div is not wrapping. Try removing the height and adding overflow:hidden to the containing .comments div. That way the height will adjust with the size of the contain.
