Hey there, I need some help with hiding the header div while scrolling in Drupal.
<header class="header<?php print theme_get_setting('header_top_menu') && !$one_page ? '' : ' header-two'; ?>">
<div class = "header-wrapper">
<div class="container">
<div class="row">
<div class="col-xs-6 col-md-4 col-lg-4 logo-box">
<div class="logo">
<a href="<?php print url('<front>'); ?>">
<img src="" class="logo-img" alt="">
</a>
</div>
</div><!-- .logo-box -->
