Table Cell Spacing Issues - css

Question

Hi Guys I am using a table: cell-spacing layout for my website and I need some help. I have a two column website, one being the sidebar and the other containing the content. However, if I add any margins within one of the table-cell divs it moves the side bar spacing with it. I need the spacing on these two cells to be different, and I am not sure how to do so.
My code is as follows:
The CSS:
content {
width : 100%;
display : table;
margin : 0 auto;
height : 100%;
}
#side_bar, #main {
display : table-cell;
}
#side_bar {
border: 1px solid #111;
width: 13%;
background: linear-gradient(#444, #111);
}
#main {
width: 65%;
}
#contact_box {
margin-left: 30%;
margin-top: 7%;
background-color: #111;
opacity: 0.3;
width: 500px;
height: 500px;
}
The HTML:
<div id="content">
<div id="main">
<div id="contact_box">
<form method="post" id="contact_form" action="contact.php">
<p>Full Name:</p> <input type="text" size="40" id="fullname" name="fullname"><br/>
<p>Email Address:</p> <input type="text" size="40" id="email" name="email"><br/>
<p>Type of Inquiry:</p> <input type="text" size="40" id="question" name="question"><br/>
<p>Message:</p> <textarea rows="20" cols="45"></textarea><br/>
<input type="submit" style="float:right; text-transform: uppercase;" value="Send">
</form>
</div>
</div>
<div id="side_bar">
<div id="divider"><h1>News Blurb</h1></div>
<div id="news"><?php //print_news(); ?></div>
<div id="divider"><h1>Featured Games</h1></div>
<div id="featured"><?php //echo $games ?></div>
</div>
</div>
Thank you for any and all help.
