To solve the issue, I recommend adjusting the padding-top of the body element.
Since the navigation block is fixed in its position, it does not physically obstruct any content on the page.
Given that you are utilizing jQuery, we can leverage its capabilities:
<script type="text/javascript">
$(document).ready(function() {
var navHeight = $('#nav').height();
$('body').css("padding-top", navHeight);
});
</script>
By dynamically setting the padding-top of the body based on the height of the navigation bar after the page has loaded, your content will seamlessly flow beneath it even if the menu items span multiple rows.
In order for this solution to function effectively, it is important to remove any fixed heights set in the following CSS rules:
#nav, .fixed-nav-bar {
height: auto;
}
Allowing the elements to adjust their heights automatically will ensure smooth functionality.
