What is the best way to achieve a seamless CSS transition for my sticky navigation bar?

Question

What is the best way to achieve a seamless CSS transition for my sticky navigation bar?

Looking to create a sticky bar with a smooth CSS transition instead of the current rough effect. Any tips or hints would be greatly appreciated! For reference, I found the exact animation I'm aiming for on this website: https://css-tricks.com/

Here is the CSS code:

#bar {  
    display:inline-block;
    width: 100%;
    height: 50px;
    max-height:50px;
    background-color: #595959;
    box-shadow: 0px 2px 2px #888888;
}
.bar-fixed {
    top: 0;
    z-index: 9999;
    position: fixed;
    width: 100%;
}

And here is the jQuery responsible for adding the necessary classes:

$(document).ready(function() {

    $(window).scroll(function () {
        console.log($(window).scrollTop());
        if ($(window).scrollTop() > 59) {
            $('#bar').addClass('bar-fixed');
        }
        if ($(window).scrollTop() < 60) {
            $('#bar').removeClass('bar-fixed');
        }
     });
});

I've attempted to achieve this using CSS transitions without success. It seems like jQuery might be the way to go, but I could use some guidance or resources such as tutorials or courses to help me learn and make informed decisions. Thank you!

One alternative approach is to utilize JQuery for animation and then adjust the class to include position: fixed

$( "#bar" ).animate({top: "0", otherStyle: "option"}, "slow");
$(".bar-not-fixed").attr("class", "bar-fixed");

By doing this, you can keep the animation separate from the code responsible for keeping the bar fixed at the top of the page.

Refer to attr and animate for more information.

To achieve a smooth transition effect, ensure the element is hidden before applying the transition.

JS:

$(document).ready(function() {

    $(window).scroll(function () {
        console.log($(window).scrollTop());
        if ($(window).scrollTop() > 59) {
            $('#bar').addClass('bar-fixed').slideDown();
        }
        if ($(window).scrollTop() < 60) {
            $('#bar').removeClass('bar-fixed');
        }
     });
});

CSS:

#bar {  
    display:inline-block;
    width: 100%;
    height: 50px;
    max-height:50px;
    background-color: #595959;
    box-shadow: 0px 2px 2px #888888;
}
#bar.bar-fixed {
    display: none;
    top: 0;
    z-index: 9999;
    position: fixed;
    width: 100%;
}

It seems like there might be some confusion with this question, as css-tricks doesn't currently feature a sticky navigation bar.

If the transition is not smooth, it could be due to removing the bar from the document flow without replacing it, causing the page to jump upwards.

One solution could be to use a library such as StickyJs. Alternatively, if you prefer to code it yourself, you can create an empty bar object that transitions between 0 height when not sticky and 50px height when sticky.

#bar-fake
{
    display:inline-block;
    width: 100%;
    height: 0;
    max-height: 0;
    background-color: #595959;
}
#bar-fake.active
{
     height: 50px;
     max-height: 50px;
}

$(document).ready(function() {

    $(window).scroll(function () 
    {
        console.log($(window).scrollTop());
        if ($(window).scrollTop() > 59) 
        {
            $('#bar').addClass('bar-fixed');
            $('#bar-fake').addClass('active');
        }
        if ($(window).scrollTop() < 60) 
        {
            $('#bar').removeClass('bar-fixed');
            $('#bar-fake').removeClass('active');
        }
    });
});

To implement this solution in your JavaScript code, you can use the following JQuery snippet:

 $('#foo').wrap('<div class="foo-container"></div>');
  $('.foo-container').height($('#foo').outerHeight());

This method is incredibly straightforward. Take a look at the live demonstration on CodePen.
