In this topic,

We are going to see how to keep an active menu on one page when redirect to the section with a sticky header.

1. Create the HTML page.

<header>
<nav class="">
<div id="brand">
<div id="logo"></div>
</div>
<div id="menu">
<ul>
<li><a href="#hero-section">Home</a></li>
<li><a href="#aboutus">About US</a></li>
<li><a href="#gallary">Gallary</a></li>
<li><a href="#reservation">Reservation</a></li>
</ul>
</div>
</nav>
<div id="hero-section">
<h1>Home</h1>
</div>
</header>
<section id="aboutus">
<h1>About US</h1>
</section>
<section id="gallary">
<h1>Gallary</h1>
</section>
<section id="reservation">
<h1>Reservation</h1>
</section>

Step: 2 Add CSS

* {
    box-sizing: border-box;
    margin: 0;
    padding: 0;
}
li a {
    color: #fff;
    background: #000;
}
.active {
   width: 100px;
   height: 20px;
   background: #fff;
   color: red;
   display: block;
   border-radius: 90px;
   text-align: center;
}
body {
   overflow-x: hidden;
   overflow-y: scroll;
}
header {
   width: 100%;
   height: 100%;
   background: #878eef;
   display: flex;
}
nav {
   width: 100%;
   height: 160px;
   background: #000000;
   display: block;
   position: absolute;
   transition: all 0.3s;
}
nav.stickyheader {
   position: fixed;
   box-shadow: 0 4px 30px -5px rgba(0, 0, 0, 0.2);
   height: 100px;
}
#brand, #menu, ul {
   display: flex;
   align-items: center;
   list-style-type: none;
}
#brand {
   padding-left: 40px;
}
#logo {
    width: 55px;
    height: 55px;
    background: #fff;
    border-radius: 50%;
    cursor: pointer;
}
#menu {
    justify-content: flex-end;
    padding-right: 40px;
}
li {
    margin-left: 20px;
}
#hero-section, #aboutus, #reservation, #gallary  {
    margin: 0 auto;
    display: flex;
    justify-content: center;
    align-items: center;
}
section {
    width: 100%;
    height:100%; 
    display: flex;
    justify-content: center;
}
#aboutus{
     background: #fa6c98;
}
#reservation{
     background: #70d09f6b;
}
#gallary {
     background: #ca1bd640;
}
#heading {
     width: 120px;
     height: 20px;
     background: #fff;
     border-radius: 90px;
     margin-top: 40px;
}

step:3 Add jQuery

$(document).ready(function () {
   $(window).scroll(function() {
  var windowTop = $(window).scrollTop();
  if( windowTop >= 100 ){
    $( "nav" ).addClass( "stickyheader" );
  }else{
    $( "nav" ).removeClass( "stickyheader" );
  }
  if(windowTop > 100){	
    $('ul').css('top', '100px')
  }else{
    $('ul').css('top', '160px');
  }
   });
   $('#menu a[href*="#"]').on('click', function (e) {
  $('html,body').animate({
       scrollTop: $($(this).attr('href')).offset().top - 100 },
       500);
      e.preventDefault();
   });
   $('#menu ul li a').click(function(){
  $('#menu li a').removeClass("active");
  $(this).addClass("active");
   });
});
