It's ashame. Such a good responsive slider and it makes a approx. 30px gap between the slider and the main navigation.
Placed the code directly above the navigation in the header.php:
<?php do_shortcode( '[responsive_slider]' ); ?> <nav id="access" role="navigation"> <h3 class="assistive-text"><?php _e( 'Main menu', 'twentyeleven' ); ?></h3>
Used the 2011 standard size for the slider pictures: 1000x288px
What am I doing wrong? How do I avoid the gap?
