Sorry if this question has already been asked. I've searched online but haven't come across a satisfactory solution. On my website, I have different background colors - blue and white. The text color in my navigation is mostly white, but I want it to change to black when hovering over a div with a white background.
Initially, I tried using this JavaScript code:
$(document).ready(function(){
$(window).scroll(function(){
var lightPos = $('#light').offset().top;
var lightHeight = $('#light').height();
var menuPos = $('.desktop-menu').offset().top;
var menuHeight = $('.desktop-menu').height();
var scroll = $(window).scrollTop();
if(menuPos > lightPos && menuPos < (lightPos + lightHeight)) {
$('.desktop-menu').addClass('menu-secondary');
$('.desktop-menu').removeClass('menu-primary');
}
else {
$('.desktop-menu').removeClass('menu-secondary');
$('.desktop-menu').addClass('menu-primary');
}
})
})
However, it seems to stop working after 3 containers. If I keep scrolling to other divs, regardless of the id I assign to a div (#light or #dark), the text no longer changes after the first 3 div containers on the page.
Appreciate any assistance!
EDIT: Struggled to get CodePen to function properly, so here's an example below.
Example HTML:
<div class="container">
<header>
<nav>
<ul class="menu">
<li><a href="#" class="menu-btn light-color">Page 1</a></li>
<li><a href="#" class="menu-btn light-color">Page 2</a></li>
<li><a href="#" class="menu-btn light-color">Page 3</a></li>
</ul>
</nav>
</header>
<div class="hero-container dark-background">
</div>
<div class="content-container light-background" id="light">
</div>
<div class="content-container dark-background">
</div>
<div class="content-container light-background" id="light">
</div>
<div class="content-container dark-background">
</div>
<div class="content-container light-background" id="light">
</div>
<div class="content-container dark-background">
</div>
</div>
Example CSS:
body {
margin: 0;
font-family: 'Poppins', sans-serif;
}
ul {
list-style-type: none;
margin: 0;
padding: 0;
}
header {
display: flex;
}
.container {
text-align: center;
}
/*-------------------- COLORS */
.dark-background {
background: #313747;
}
.light-background {
background: #f4f4f4;
}
.dark-color {

}
.light-color {

}
/*-------------------- NAVIGATION */
nav {

height: auto;
width: 100%;
margin: auto;
z-index: 10;
}
.menu {

text-align: left;

}
.menu li a {
margin-right: 2em;
font-size: 1.2em;
font-weight: 700;
text-decoration: none;
}
/*-------------------- HERO CONTAINER */
.hero-container {

}
/*-------------------- CONTENT CONTAINER */
.content-container {

Example JS:
$(document).ready(function(){
$(window).scroll(function(){
var lightPos = $('#light').offset().top;
var lightHeight = $('#light').height();
var menuPos = $('.menu-btn').offset().top;

if(menuPos > lightPos && menuPos < (lightPos + lightHeight)) {
$('.menu-btn').addClass('dark-color');
$('.menu-btn').removeClass('light-color');
}
else {
$('.menu-btn').removeClass('dark-color');
$('.menu-btn').addClass('light-color');
}
})
