I modified the template (template.css, templateDetails.xml and index.php) for adding a new position I called slideshow2. When I view the page in the browser between modules slideshow2 and "home cl / cr" there's a transparent strip in which I see the contents of the footer. How can I fix the problem?
Here is the modified code
template.css
#jf-slideshow2 {
    background-clip: border-box;
    background-color: #00446D;
    background-image: url(../images/banner_ORIG.jpg);
    background-origin: padding-box;
    background-position: center center;
    background-repeat: no-repeat;
    background-size: cover;
	background-attachment: fixed;
    position: relative;
    z-index: 50;
}
 
index.php
<?php
	if ($menu->getActive() == $menu->getDefault()) : ?>
    <div id="jf-slideshow">
		<div class="main clearfix">
 
		</div>
	</div>
	<div id="jf-slideshow2">
		<div class="main clearfix">
 
		</div>
	</div>
	<?php endif; ?>
Thanks in advance
