Tips for creating a fixed top navbar

I recently created a one-page website and wanted to make my navbar fixed. Currently, it looks like the image linked below:

In order to achieve this, I floated the logo to the left, the navbar to the right, and set the position to absolute so that the right and bottom could be set to zero.

Here is my HTML and some of the CSS:

<div class="navigation">
    <nav id="site-navigation" class="main-navigation" role="navigation">
        <div class="menu-menu-1-container">
            <ul id="primary-menu" class="menu">
                <li id="menu-item-55" class="menu-item menu-item-type-post_type menu-item-object-page current-menu-item page_item page-item-5 current_page_item menu-item-55"><a href="http://localhost/scentology/">Home</a></li>
                <li id="menu-item-107" class="menu-item menu-item-type-custom menu-item-object-custom menu-item-107"><a href="#about">About</a></li>
                <li id="menu-item-144" class="menu-item menu-item-type-custom menu-item-object-custom menu-item-144"><a href="#products-and-services">Products &#038; Services</a></li>
                <li id="menu-item-142" class="menu-item menu-item-type-custom menu-item-object-custom menu-item-142"><a href="#scent-marketing">Scent Marketing</a></li>
                <li id="menu-item-145" class="menu-item menu-item-type-custom menu-item-object-custom menu-item-145"><a href="#clients-and-industries">Clients &#038; Industries</a></li>
                <li id="menu-item-143" class="menu-item menu-item-type-custom menu-item-object-custom menu-item-143"><a href="#contact">Contact Us</a></li>
            </ul>
        </div>      
    </nav>  
</div>

.navigation{
    height:40px; line-height:40px;
}
nav#site-navigation {
    position: absolute;
    right: 0;
    bottom: 0;
}

Although I am not very familiar with scripting yet, I attempted to adjust this code snippet:

<script>
// Create a clone of the menu, right next to original.
$('.navigation').addClass('original').clone().insertAfter('.navigation').addClass('cloned').css('position','fixed').css('top','0').css('margin-top','0').css('z-index','500').removeClass('original').hide();
scrollIntervalID = setInterval(stickIt, 10);
function stickIt() {
    var orgElementPos = $('.original').offset();
    orgElementTop = orgElementPos.top;               
    if ($(window).scrollTop() >= (orgElementTop)) {
        // scrolled past the original position; now only show the cloned, sticky element.
        // Cloned element should always have same left position and width as original element.     
        orgElement = $('.original');
        coordsOrgElement = orgElement.offset();
        leftOrgElement = coordsOrgElement.left;  
        widthOrgElement = orgElement.css('width');
        $('.cloned').css('left',leftOrgElement+'px').css('top',0).css('width',widthOrgElement).show();
        $('.original').css('visibility','hidden');
    } else {
        // not scrolled past the menu; only show the original menu.
        $('.cloned').hide();
        $('.original').css('visibility','visible');
    }
}
</script>

The menu became fixed, but the issue is that I can't see it properly due to the position properties. I had to adjust the bottom value to make it visible. This means it will only work when I scroll to the bottom. When I try to scroll back to the top, the menu disappears.

Is there a way to keep the navbar fixed at the top when scrolling down and return it to its default position when scrolling up?

Answer №1

Try to keep your code concise and straightforward.

Swap out your current scripting with the given jQuery code that checks for the scrolling position offset:

(function( $ ){     
   var navOffset = jQuery("nav").offset().top; 
   jQuery(window).scroll(function() {
       var scrollPos = jQuery(window).scrollTop();
        if (scrollPos >= navOffset) {
            jQuery("nav").addClass("fixed");
        } else {
            jQuery("nav").removeClass("fixed");
        }
    });
})(jQuery);

Any styling adjustments should be made within the .fixed class. Note that this class will be removed each time you scroll back to the top.

Below is the provided CSS for reference:

.fixed{
    position: fixed !important;
    z-index: 9999;
    top: 4%;
    width: 100%;
    text-align: center;
}

Depending on your specific content, some tweaking of the top percentage may be necessary.

Answer №2

To enhance your website's appearance, include the following CSS:

.navigation{
height:40px; 
line-height:40px;
position:fixed;

After defining the navigation class, enclose the elements within a div named content
For example:

<div id='content'>
<!--Insert main content here!-->
</div>

The corresponding CSS for content:

#content {
padding-top: someValueInPixel;
}

Determine the height of your navigation bar and substitute someValueInPixel with that measurement.

This method eliminates the need for JavaScript to keep your navbar fixed at the top and renders the nav#site-navigation css unnecessary.

Reasons for using position:fixed;
Referencing w3schools.com:

    This property fixes the element in relation to the browser window

Thus, your designated element remains at the top even as you scroll through the page.
