Adjust the color of the navigation bar as you scroll

Question

Adjust the color of the navigation bar as you scroll

I recently used pure JavaScript to change the color of my navbar after scrolling. Surprisingly, it worked perfectly fine on Google Chrome without any issues. However, when I decided to test it on Firefox, the feature stopped working altogether.

Can anyone provide me with some advice on how to fix this problem? Thank you in advance.

var myNav = document.getElementById("nav");

window.onscroll = function () {
    "use strict";
    if (document.body.scrollTop >= 280) {
        myNav.classList.add("scroll");
    } else {
        myNav.classList.remove("scroll");
    }
};

body {
  margin:0;
  padding:0;
  height:4000px;
}
.nav {
  position:fixed;
  width:100%;
  height:60px;
  background-color:#111;
  transition:all .5s ease-in-out;
}
.scroll {
  background-color:transparent;
}

Answer №1

In case you are utilizing pure JavaScript:

When it comes to overflow, Firefox and IE have it at the html level, while Chrome, Safari, and Opera place it at the body level:

For additional information, refer to this link:

var body = document.body; // For Chrome, Safari, and Opera

var html = document.documentElement; // Firefox and IE have the overflow at this level by default. To accommodate these browsers, we use the documentElement property

To ensure cross-browser functionality, use the following snippet:

if (document.body.scrollTop >= 280 || document.documentElement.scrollTop >= 280) {

Cheers!

var myNav = document.getElementById("nav");

window.onscroll = function() {
  "use strict";
  if (document.body.scrollTop >= 280 || document.documentElement.scrollTop >= 280) {
    myNav.classList.add("scroll");
  } else {
    myNav.classList.remove("scroll");
  }
};

body {
  margin: 0;
  padding: 0;
  height: 4000px;
}
.nav {
  position: fixed;
  width: 100%;
  height: 60px;
  background-color: #111;
  transition: all .5s ease-in-out;
}
.scroll {
  background-color: transparent;
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

<div id="nav" class="nav"></div>

If jquery is your choice:

var myNav = $("#nav");

$(window).on('scroll', function() {
  "use strict";
  if ($(window).scrollTop() >= 280) {
    myNav.addClass("scroll");
  } else {
    myNav.removeClass("scroll");
  }
});

body {
  margin: 0;
  padding: 0;
  height: 4000px;
}
.nav {
  position: fixed;
  width: 100%;
  height: 60px;
  background-color: #111;
  transition: all .5s ease-in-out;
}
.scroll {
  background-color: transparent;

$(window).scroll(function() {
if ($(this).scrollTop() > 20){  
  $('#navBar').css({attribute: "value"});
    } else {
        $('#navBar').css({attribute: "value"});
    }
});

While not a direct answer, I have found this code to work effectively across various browsers like IE, Edge, Safari, Chrome, and Firefox.

Here's a tip to customize your website. Just replace the "280" with the number of pixels you prefer for the scroll distance before the navbar background color turns transparent.

HTML:

<div id="navbar"></div>

JavaScript:

$(function() {
 $(window).on("scroll", function() {
    if($(window).scrollTop() > 280) {
        //background on scroll
        $("#navbar").addClass("scroll");
    } else {
        //background at top
       $("#navbar").removeClass("scroll");
    }
  });
});

CSS:

#navbar {
background-color:#111;
transition:all .5s ease-in-out;
}
.scroll {
background-color:transparent;
}
