move div class under another div

RESPONSIVE THEME : front-page template. Off localhost so no link availible. (code in backquotes)
html code:

<div id="featured" class="grid col-940">

		<div class="grid col-460">

			<h1 class="featured-title">
				<?php
				if ( isset( $responsive_options['home_headline'] ) && $db && $empty )
					echo $responsive_options['home_headline'];
				else
					_e( 'Hello, World!', 'responsive' );
				?>
			</h1>

			<h2 class="featured-subtitle">
				<?php
				if ( isset( $responsive_options['home_subheadline'] ) && $db && $empty )
					echo $responsive_options['home_subheadline'];
				else
					_e( 'Your H2 subheadline here', 'responsive' );
				?>
			</h2>

			<p>
				<?php
				if ( isset( $responsive_options['home_content_area'] ) && $db && $empty )
					echo do_shortcode( $responsive_options['home_content_area'] );
				else
					_e( 'Your title, subtitle and this very content is editable from Theme Option. Call to Action button and its destination link as well. Image on your right can be an image or even YouTube video if you like.','responsive' );
				?>
			</p>

			<strong><?php if ($responsive_options['cta_button'] == 0): ?>  

				<div class="call-to-action"></strong>
					<a>" class="blue button">
						<?php
						if( isset( $responsive_options['cta_text'] ) && $db && $empty )
							echo $responsive_options['cta_text'];
						else
							_e('Call to Action','responsive');
						?>
					</a>

				</div><!-- end of .call-to-action -->

			<?php endif; ?>         

		<strong></div><!-- end of .col-460 -->

		<div id="featured-image" class="grid col-460 fit">

		  <?php $featured_content = ( !empty( $responsive_options['featured_content'] ) )</strong> ? $responsive_options['featured_content'] : '<img class="aligncenter" src="' . get_template_directory_uri() . '/images/featured-image.png" width="440" height="300" alt="" />'; ?>

			<?php echo do_shortcode( $featured_content ); ?>

		</div><!-- end of #featured-image --> 

	</div><!-- end of #featured -->

	<?php

I want to move the call to action div to below the feature image div.
tried float with margins but can’t seem to get it centered and about 20px below the feature image.
