I tried putting the following code in the custom css section and removing it from the main.css.tpl to test and see if the custom css section was working. When I did that the search box did not have the css. Why isn’t the custom css section working for the sticky header?

.tb_sticky_container .tb_widget_site_search.tbCloned {
min-width: 180px;
<?php if ($lang_dir == ‘ltr’): ?>
padding-right: 10px;
<?php else: ?>
padding-left: 10px;
<?php endif; ?>
}
