How can I make multiple on scroll fixed headers/navbars that stick at the very top of the page?

Demo:

Explanation:

position: sticky with correct markup will do the work

PS: I know there is already an answer using position: sticky but in that solution the previous header doesn't stop but overlaps with the next one. In my solution is stops before the next sticking.


Without your javascript code, i can suggest you use position:sticky which achieves what you want.

It is pretty well supported in modern browsers caniuse position sticky

html, body {
  margin: 0;
  padding: 0;
  width: 100%;
  height: 100%;
  font-family: 'Roboto', sans-serif;
  position:relative;
}

@import url("https://fonts.googleapis.com/css?family=Roboto:100");

h1 {
  letter-spacing: 3px;
  margin: 0;
  padding-left: 10px;
  padding-top: 10px;
  color: #fff;
  font-weight: 100;


}

.header {
  width: 100%;
  height: 50px;
  position: sticky;
top: 0px;
}

.header:nth-of-type(1){
   background-color: dodgerblue;

}

.header:nth-of-type(2){
   background-color: rebeccapurple;
}

.header:nth-of-type(3){
   background-color: chartreuse;
}

.content {
  width: 100vw;
  height: 100vh;
  background: linear-gradient(70deg, orange, crimson);
  padding-top: 50px;
    
}
<section>
<header class="header"><h1>HEADER 1</h1></header>
<div class="content"><h1>CONTENT</h1></div>
<header class="header"><h1>HEADER 2</h1></header>
<div class="content"><h1>CONTENT</h1></div>
<header class="header"><h1>HEADER 3</h1></header>
<div class="content"><h1>CONTENT</h1></div>
</section>


If you want header 2 and header 3 to be sticky, but show below the next add top with padding to each header (here header-2 has top: 50px; so it will not override the first, and the third has top: 100px;).

html, body {
  margin: 0;
  padding: 0;
  width: 100%;
  height: 100%;
  font-family: 'Roboto', sans-serif;
  position:relative;
}

@import url("https://fonts.googleapis.com/css?family=Roboto:100");

h1 {
  letter-spacing: 3px;
  margin: 0;
  padding-left: 10px;
  padding-top: 10px;
  color: #fff;
  font-weight: 100;
}

.header {
  width: 100%;
  height: 50px;
  position: sticky;
  top: 0px;
}

.header:nth-of-type(1){
   background-color: dodgerblue;

}

.header:nth-of-type(2){
   background-color: rebeccapurple;
}

.header:nth-of-type(3){
   background-color: chartreuse;
}

.content {
  width: 100vw;
  height: 100vh;
  background: linear-gradient(70deg, orange, crimson);
  padding-top: 50px;
    
}

.header-2{
  top: 50px;
}

.header-3{
  top: 100px;
}
<section>
<header class="header"><h1>HEADER 1</h1></header>
<div class="content"><h1>CONTENT</h1></div>
<header class="header header-2"><h1>HEADER 2</h1></header>
<div class="content"><h1>CONTENT</h1></div>
<header class="header header-3"><h1>HEADER 3</h1></header>
