I was experiencing this issue as well. The way that I resolved this was by adding CSS within the Contact Form. For example..
<div style=”float: left; height: 500px; width:500px; padding:15px;”>
<p>Your Name (required)
[text* your-name] </p>
<p>Your Email (required)
[email* your-email] </p>
<p>Subject
[text your-subject] </p>
<p>Your Message
[textarea your-message] </p>
<p>[submit “Send”]</p>
</div>
