one page slider jump

I created one page slider from Roots Wordpress theme.
That the slider jumps from bottom to top when I reach the point.
- the issue is that there is a small jump between the header and full-widthbanner-container

this is my code for the jump in _main.js

common: {
init: function() {
$('#nav').affix({
offset: {
top: $('.fullwidthbanner-container').height()
}
});
}

 

Sounds like a CSS issue with .fullwidthbanner-container

Check to make sure the margin and padding is set the way you need it for both .fullwidthbanner-container and whatever is containing it (probably #nav needs to be margin-top: 0px; padding-top: 0px; but I can't say for sure without seeing the full code )

 

sorry here is the site http://projects.qbf.ie/sticky-navbar/

and also issue with shortcodes. when i add shortcode lie [gallery id=1] it shows on front end gallery [gallery id=1] . using this on front-page.php


<div id="container">
<a name="top"></a>
<?php
$args = array(
'sort_order' => 'ASC',
'sort_column' => 'menu_order', //post_title
'hierarchical' => 1,
'exclude' => '',
'child_of' => 0,
'parent' => -1,
'exclude_tree' => '',
'number' => '',
'offset' => 0,
'post_type' => 'page',
'post_status' => 'publish'
);
$pages = get_pages($args);
//start loop
foreach ($pages as $page_data) {
$content = apply_filters('slider', $page_data->post_content);
$title = $page_data->post_title;
$slug = $page_data->post_name;
?>
<div class='<?php echo "$slug" ?>'><a name='<?php echo "$slug" ?>'></a>

<?php echo "$content" ?>
</div>




<?php
}
get_footer();
?>
